Description

200815875 IX. Description of the Invention: [Technical Field] The present invention relates to an optical compensation film, a polarizing plate, and a liquid crystal display device. In particular, the present invention relates to a vertical alignment type liquid crystal display device, and an optical compensation film and a polarizing plate used in the liquid crystal display device. [Prior Art] A wide viewing angle liquid crystal display device using the VA mode has been put into practical use, and the demand for liquid crystal display devices has been rapidly increasing in the market for high-quality images such as televisions. The VA mode liquid crystal display device generally has the advantage of so-called high contrast compared with other liquid crystal display modes, but there is a problem that the contrast and the color odor change with the viewing angle. In this regard, for example, a method of using two types of retardation films having different optical characteristics has been disclosed, thereby providing a clear and achromatic VA mode liquid crystal display device even when viewed from an oblique direction in black display (for example, refer to International Publication No. 2003/032060 manual). However, when the two types of retardation films are actually incorporated in a liquid crystal display device, most of them are incorporated in a liquid crystal display device integrally with a polarizing plate. However, in this case, after the polarizing plate is produced, it is necessary to have Two pieces of phase difference film showing predetermined optical characteristics are bonded together. Therefore, there are problems in that the manufacturing process becomes complicated, the productivity is lowered, the manufacturing cost is improved, and the like, and improvement is sought. In this regard, for example, an optical compensation film having a transparent support and an optical 200815875 anisotropic layer formed of a discotic liquid crystalline molecule has been proposed as the VA mode in Japanese Laid-Open Patent Publication No. 2000-304931. An optical compensation film for a liquid crystal display device. By using a deuterated cellulose film as a transparent support, the deuterated cellulose film can be utilized as a protective film for a polarizing plate, and the above-mentioned productivity problem can be solved. However, in order to obtain the optical characteristics necessary for optical compensation of the liquid crystal display device of the VA mode, it is necessary to make the thickness of the optically anisotropic layer somewhat thicker when the optical anisotropic layer is formed by coating. There will be problems with uneven coating. Further, Japanese Laid-Open Patent Publication No. 2005-128050 proposes a phase difference plate which can be used as an optical compensation for a liquid crystal display device or the like of a VA mode, and which has optically negative refractive index anisotropy and The absolute value of the refractive index optical anisotropy is 〇· 060 or more and 0.085 or less, and Re 値 is 10 to 10 nm, and the disk is substantially horizontally aligned with respect to the plate surface of the phase difference plate. A phase difference plate of a liquid crystal compound. Further, the retardation of the phase difference plate formed of a polymer film or the like is not the same with respect to any wavelength, but varies to some extent with the wavelength of the incident light (hereinafter, this property is called "Wavelength dispersion"). Among the polymer films, those having a wavelength dispersion which exhibits an increase in hysteresis when the wavelength of incident light is shortened (hereinafter referred to as "paradispersivity") and a wavelength at which hysteresis is decreased when the wavelength of incident light becomes shorter Dispersibility (hereinafter referred to as "reverse dispersion"). On the other hand, the liquid crystal cell also has wavelength dispersion in terms of birefringence, and in order to obtain more favorable optical compensation of the liquid crystal cell, the wavelength dispersion of the hysteresis of the phase difference plate may need to be similarly adjusted. For example, it is proposed to use a negative C plate for optical compensation in the black display of the VA mode liquid crystal cell. However, when the thickness of the negative C plate is retarded (Rth), the wavelength of 200815875 is not dispersed with the wavelength dispersion of the VA mode liquid crystal cell. When similar, it will produce a change in color with the viewing angle (some cases called "color shift"). However, the polymer film which has been used as a phase difference plate of a VA mode liquid crystal cell is difficult to control the wavelength dispersion of hysteresis, and a phase difference plate which exhibits an ideal wavelength dispersion similar to the birefringence of a liquid crystal cell is produced. difficult. In particular, in the case of a polymer film, it is difficult to find an Rth which exhibits a certain absolute enthalpy size, and the wavelength dispersion of the Rth is an optical property of dispersibility, and therefore, even if an additive or the like is added for control, There is a problem that wavelength dispersion and Rth cannot be controlled at the same time. Further, when an optically anisotropic layer is formed on a polymer film to form an optical compensation film, the wavelength dispersibility of the optical anisotropic layer is inevitably lowered due to the wavelength dispersion of the polymer film, so that it is difficult to obtain Overall predetermined wavelength dispersion. Under such circumstances, it is required to provide an optical compensation film having excellent optical compensation thinning ability for liquid crystal cells of various modes, particularly VA mode. In addition, in order to eliminate the fact that the polarizing plate of the vertical Nicol state which is mainly viewed from the oblique direction is not the appearance of the vertical state, Yu is proposed to use one on the pages 525 to 527 of the IWD 02 table. A negative C plate is added along with a method of using a reverse dispersion of the positive A plate. The positive a plate of the reverse dispersion like this is sold under the trade name of the pure auxiliary W R (Teijin Chemical Co., Ltd.). SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] An object of the present invention is to provide a novel optical compensation film useful for optical compensation of a VA mode liquid crystal display device, and a polarizing plate, and having improved viewing angle characteristics VA mode liquid crystal display device. 200815875 'By the results of the inventors' research, it is understood that in the case of using the reverse dispersion of the positive A plate and the negative C plate to optically compensate the liquid crystal cell of the VA mode, in the case of the negative C plate, the thickness direction is required. The hysteresis is a smooth dispersion of steeper slope than the wavelength dispersion of the liquid crystal used for the liquid crystal cell. Thus, the first aspect of the present invention provides an optical compensation film which is highly productive, has no or less optical characteristics and uneven film thickness, and can optically compensate liquid crystal cells, particularly VA mode liquid crystal cells, as The subject, as well as to provide a polarizing plate using it. Further, the first aspect of the present invention provides a display device which has no or little display unevenness due to an optical compensation film and which has excellent optical display compensation characteristics, and particularly provides a VA mode liquid crystal. The display device is a problem. Moreover, as a result of the study by the present inventors, it is understood that a polymer film which has been used as a phase difference plate of a liquid crystal cell of a VA mode is difficult to control the wavelength dispersion of hysteresis, thereby producing a birefringence which exhibits a liquid crystal cell. A wavelength difference plate having a wavelength dispersibility (usually a dispersibility) of equal or steeper slope dispersibility is difficult, especially in the case of a polymer film, which is difficult to find to exhibit a certain degree of absolute 値 size. Rth and the wavelength dispersibility of the Rth are optical properties of cis-dispersibility; therefore, even if an additive or the like is added for control, there is a problem that wavelength dispersion and Rth cannot be simultaneously controlled. Accordingly, the second aspect of the present invention provides a sufficient Rth on a liquid crystal cell in optical compensation (for example, optical compensation in black display of a liquid crystal cell of a VA mode), and its wavelength dispersion is a smooth display. An optical compensation film that functions as a C-plate function, which is dispersible and can be stably manufactured, is a problem. Further, the second aspect of the present invention is also provided in the liquid crystal display device as a problem of 200815875, and in particular, an optical compensation film which is useful for optical compensation of a liquid crystal display device of the VA mode and which is excellent in productivity and A polarizing plate is a problem. Further, the second aspect of the present invention provides a liquid crystal display device which has a reduced viewing angle characteristic and particularly a change in color chromaticity depending on the viewing angle, and in particular, a liquid crystal display device which provides a VA mode as a subject. Further, as a result of the inventors' research, it is understood that when an optically anisotropic layer is continuously formed on a long support using a discotic liquid crystal, in order to obtain desired optical characteristics (especially high Rth値), coating is performed. The greenness of the film thickness becomes thick, and thus the problem of uneven coating occurs. Therefore, the third aspect of the present invention provides an optical compensation film which is not uneven and can optically compensate the liquid crystal cell correctly, and provides a polarizing plate and a liquid crystal display device using the optical compensation film.

[Polymer film] The polymer film of the optical compensation film of the first aspect of the present invention satisfies the following formula (1 - 1) to (1 - 3) ° - 50 nm ^ Rth (590) ^ 1 50 nm · · • (1 - 1) -5 nm^Rth(450)- Rth(550) · · · (1 - 2) 0^Re(590)^10 nm · •• (1- 3 In the formula (1 - 1), Rth (590) is preferably - 20 nm or more 'more than 〇 nanometer or more, more preferably 20 nm or more, and particularly preferably 40 nm or more. Further, Rth (590) is preferably 120 nm or less, more preferably 100 nm or less, and particularly preferably 90 nm or less.

In the formula (1 - 3), Re (590) is preferably 0 to 5 nm. Further, when Rth (590) is 20 nm or more, it is preferable to satisfy the following formula (1 to 5). 1.0<Rth(450)/Rth(550)<4.0 Equation (1-5)

Rth (4 50) / Rth (550) is preferably 1.03 or more, more preferably 1.06 or more, and particularly preferably 1.09 or more. Further, Rth (450) / Rth (550) is preferably 3.0 or less, more preferably 2.0 or less, and particularly preferably 1.5 or less. The material of the polymer film described above is not particularly limited, and a polymer -23 - 200815875 film formed of various materials satisfying the above optical characteristics can be used. Among them, from the viewpoint of inexpensive raw materials and suitability of polarizing plate processing, it is preferred to use a cellulose-based film. In addition, in the present specification, the "deuterated cellulose-based film" means a cellulose which is a main component contained in a polymer composition constituting a film, and specifically, is contained in relation to the total weight of the film. It is 70% by mass or more, and more preferably 80% by mass or more of deuterated cellulose. In the present specification, the following "mainly included" and "principal component" mean the same meaning. Deuterated cellulose means that a part or all of the hydroxyl group in the cellulose is substituted with a mercapto group. The degree of substitution of deuterated cellulose means the ratio of the three hydroxyl groups present in the constituent units of cellulose ((/3) 1,4-glycidically bonded glucose). The degree of substitution (degree of deuteration) can be calculated by measuring the amount of bound fatty acid per unit mass of the cellulose. The measurement method was carried out based on "ASTM D 817-91". Other preferred cellulose fibers used in the raw material of the above polymer film are mixed fatty acid esters having a total thiol substitution degree of 2.70 to 30.00. More preferably, it is a mixed fatty acid ester having a mercapto group having a total thiol substitution degree of 2.80 to 3.00 and a carbon number of 3 to 4. The degree of thiol substitution of the above mixed fatty acid ester is more preferably 2.85 to 2.97. Further, the degree of substitution of the thiol group having a carbon number of 3 to 4 is preferably from 0.1 to 2.0, more preferably from 0.3 to 1.5. The deuterated cellulose used in the first aspect of the invention preferably has a mass average degree of polymerization of from 350 to 800, more preferably from 370 to 600. Further, the deuterated cellulose used in the first aspect of the present invention preferably has a number average molecular weight of 70,000 to 230,000, more preferably has an average molecular weight of 75,000 to 230,000, and preferably has -24 to 200815875. The average molecular weight of 78,000~1 20,000. The deuterated cellulose used in the first aspect of the present invention can be synthesized by using phthalic anhydride and acid chloride as a deuteration agent. In the case where the above-mentioned deuteration agent is an acid anhydride, an organic acid (e.g., acetic acid) and dichloromethane are used as a reaction solvent. Further, a protic catalyst such as sulfuric acid can be used as a catalyst. In the case where the oximation agent is an acid chloride, an alkaline compound can be used as a catalyst. The most common synthetic method in the industry, which consists of an organic acid (acetic acid, propionic acid, butyric acid) or an anhydride (acetic anhydride, propionic anhydride, butyric anhydride) containing an ethyl hydrazide group and other sulfhydryl groups. The organic acid component is mixed, and cellulose is esterified to synthesize cellulose. Among the methods, such as cellulose, such as 花i nte r and wood pulp, most of the cases are activated by an organic acid such as acetic acid, and then present in the sulfuric acid catalyst. Next, esterification is carried out using a mixture of organic acid components as described above. The organic acid anhydride component is generally used in excess relative to the amount of hydroxyl groups present in the cellulose. In this esterification treatment, in addition to the esterification reaction, a hydrolysis reaction (depolymerization reaction) of a cellulose main chain ((/3) 1,4-glycidyl bond) is carried out. When the hydrolysis reaction of the main chain is carried out, the degree of polymerization of the cellulose ester is lowered, and the physical properties of the produced cellulose ester film are lowered. Therefore, the reaction conditions such as the reaction temperature are preferably determined in consideration of the polymerization degree and molecular weight of the obtained cellulose ester. In order to obtain a cellulose ester having a degree of polymerization (large molecular weight), it is important to adjust the maximum temperature in the esterification reaction step to 5 (the following is important. The maximum temperature is preferably adjusted to 35 to 50 ° C, preferably It is adjusted to 37 to 47 ° C. If the reaction temperature is 3 5 C or more, it is preferable because the esterification reaction proceeds smoothly from -25 to 200815875. Further, if the reaction temperature is 50 ° C or lower. It is preferable because the polymerization degree of the cellulose ester is not lowered, which is not preferable, and when the reaction is stopped while suppressing the temperature rise after the esterification reaction, the decrease in the degree of polymerization can be further suppressed. And it is possible to synthesize a cellulose ester having a high degree of polymerization. That is, when a reaction stopping agent (for example, water, acetic acid) is added after the end of the reaction, an excess amount of an acid anhydride which is not related to the esterification reaction may be accompanied by hydrolysis to produce an organic Acid. This hydrolysis reaction causes the temperature inside the reaction device to rise with intense heat generation. If the rate of addition of the reaction stop agent is not excessive, it will not occur beyond the reaction device. The cooling ability is rapidly generated, the hydrolysis reaction of the cellulose main chain proceeds remarkably, and the degree of polymerization of the obtained cellulose ester is lowered. Further, in the esterification reaction, a part of the catalyst is bonded to cellulose. Most of them are dissociated from the cellulose in the addition of the reaction stopping agent. At this time, if the rate of addition of the reaction stopping agent is not excessively large, the sufficient reaction time required for dissociation of the catalyst can be ensured, and thus it is difficult to occur. The problem that the catalyst is bonded to the cellulose state remains, etc. The cellulose ester which is partially bonded with a strong acid catalyst has a very poor stability. It is easily decomposed by heat during drying of the product to cause a decrease in polymerization degree. For these reasons, after the esterification reaction, it is preferred to add the reaction stopper at a time of 4 minutes or longer, more preferably 4 to 3 minutes, and it is desirable to stop the reaction. Further, the addition time of the reaction stopper is 3 When it is less than 0 minutes, it is preferable because it does not cause a problem of decline in industrial productivity, etc. As a reaction stop agent, water and alcohol which decompose an anhydride can be used normally. In order not to precipitate the triester having low solubility in various organic solvents, it is preferred to use -26-200815875 as a reaction stop agent using a mixture of water and an organic acid. When the esterification reaction is carried out under the above conditions In the case where a high molecular weight cellulose ester having a mass average degree of polymerization of 500 or more can be easily synthesized.

The solution may be taken out from the container while being cooled, or may be extracted by a container, cooled by a heat exchanger or the like, and supplied to the container. Although the cooling temperature at this time can be cooled to room temperature, it is cooled to a temperature of 5 to 10 t lower and the flow rate is delayed at such a temperature, which is preferable because the viscosity of the coating liquid is lowered.

In addition, the "horizontal alignment" in the first aspect of the present invention means that the long axis direction of the molecules of the discotic liquid crystalline compound (ie, the disk surface of the core) is parallel to the horizontal plane of the liquid crystal layer ( For example, in the case where the liquid crystal layer is formed on the support, it is the surface of the support; however, it is not required to be strictly parallel.

The hydrocarbon radical having 8 or less atoms other than hydrogen may be a hydrocarbon radical having a substituent such as a halogenated hydrocarbon radical, and for example, 'for example, it may be a methyl radical, an ethyl radical, or a C. a radical, a butyl radical, a phenyl radical, a tolyl radical, a chlorophenyl radical, a bromophenyl radical, a benzinyl radical, or the like. The matching of the sensitization wavelength and the light source is necessary for high sensitivity. A photopolymerization initiator with a photosensitive area of 330 nm to 450 nm, which has good compatibility with UV lamps such as metal halide lamps and high-pressure mercury lamps. It can not only promote the polymerization of low-power UV light. Moreover, the obtained optical compensation film has the advantage of less coloration. Further, as described above, when the bulkiness of the radical of the photopolymerization initiator is small, the degree of adhesion between the optical anisotropic layer and the alignment film becomes good. It is presumed that this is due to the fact that the polymerizable radical of the optically anisotropic layer having a small bulkiness is diffused into the alignment film, so that a chemical bond is formed on the surface of the alignment film, and hardening occurs in the vicinity of the alignment film. Improved adhesion. Further, the photopolymerization initiator is preferably one which can decompose more than 30% by the energy of 100 mJ / c m2. The example of the photopolymerization initiator which can be used in the first aspect of the present invention is described below, but it is not limited to these. -76- 200815875 _ Q, p〇k N CCI3 A-l

The amount of the photopolymerization initiator to be used is preferably 0.01 to 20% by mass, more preferably 0.5 to 5% by mass, based on the composition (solid content in the case of preparing a coating liquid). It is preferred to use ultraviolet light for light irradiation of the molecular polymer of the liquid crystalline compound. The irradiation energy is preferably from 20 mJ/cm 2 to 50 J/cm 2 , more preferably from 1 〇〇 to 800 mJ/cm 2 . In order to promote the photopolymerization reaction, light irradiation may also be carried out under heating. The thickness of the optically anisotropic layer formed is preferably from 0.1 to 10 μm, more preferably from 0.5 to 5 μm. When the optically anisotropic layer is formed of a polymerizable composition containing a liquid crystal compound, it is preferable to achieve good adhesion between the optically anisotropic layer and the lower layer (alignment film or the like). It is such that the above composition contains a polyfunctional monomer. In the case where the aforementioned optically anisotropic layer is required to exhibit a high Rth, the film thickness of the layer is required to be relatively thick. When the film thickness of the directional layer of light is thick, the adhesion to the alignment film tends to deteriorate. By having a polyfunctional monomer having two or more functional groups in the optically isotropic layer-forming composition described above, it is preferable because the adhesion can be improved. A polyfunctional monomer having 2 or more polymerizable groups in the molecule, for example, may be an ester of a polyhydric alcohol and (meth)acrylic acid (for example, ethylene glycol di(meth)acrylate, butanediol Di(meth)acrylate, hexanediol di(meth)acrylate, 1,4-cyclohexanedi(meth)acrylate, pentaerythritol tetra(meth)acrylate], pentaerythritol tris(methyl) Acrylate, trimethylolpropane tri(meth)acrylate, trimethylolethane tri(meth)acrylate, dipentaerythritol tetra(meth)acrylate, dipentaerythritol penta(meth)acrylate, two Pentaerythritol hexa(meth) acrylate, pentaerythritol hexa(meth) acrylate, 1,2,3-cyclohexane tetramethacrylate, polyurethane acrylate, polyester acrylate, The above ethylene oxide modified body, ethyl benzene and its derivatives (for example, 1,4 -divinylbenzene, 4-vinylbenzoic acid-2-propenylethyl ester, 1,4-divinyl Cyclohexanone), vinyl hydrazine (eg, divinyl fluorene), acrylamide (e.g., methylenebis acrylamide) and methacrylamide. The above monomers may be used in combination of two or more kinds. It is particularly preferable to use a polyfunctional monomer having a double bond of 4 or more in the molecule. The double bond is preferably an ethylenic (aliphatic) unsaturated double bond. The number of intramolecular double bonds is preferably 4 to 20, more preferably 5 to 15, and most preferably 6 to 10. The polyfunctional monomer is preferably a polyol having four or more hydroxyl groups in the molecule, and an ester of an unsaturated fatty acid. Examples of the unsaturated fatty acid include acrylic acid, methacrylic acid, maleic acid, and itaconic acid. More preferably, it is acrylic acid and methacrylic acid. -79 - 200815875 A polyol having four or more hydroxyl groups in the molecule is preferably a tetravalent or higher alcohol or an oligomer of a trivalent or higher alcohol. The oligomer is a molecular structure having a linkage with a polyvalent alcohol by an ether bond, an ester bond or a urethane bond. Preferably, it is an oligomer having a molecular structure in which a polyvalent alcohol is bonded by an ether bond. An ester of a polyol and a (meth)acrylic acid, which comprises pentaerythritol tetra(meth)acrylate, dipentaerythritol penta(meth)acrylate, dipentaerythritol hexa(meth)acrylate, polyether polyol ( A poly(meth)acrylate of a methyl (meth)acrylate, a poly(meth)acrylate of a polyester-based polyol, and a polyurethane-based polyol. Commercial products of polyfunctional monomers can also be used. The monomer composed of the ester of polyol and acrylic acid is Mitsubishi Rayon Co., Ltd. (trade name: Da Yabim UK -41 54), East Asia Synthetic (stock) company (trade name · Aronicus M450 ), and Nippon Kayaku Co., Ltd. (trade name: KYARAD·DPHA, SR355) are commercially available. It is also possible to use two or more kinds of polyfunctional monomers. It is also possible to use a polyfunctional monomer having 4 or more double bonds in the molecule and a monomer having 1 to 3 double bonds in the molecule. The use of the monomer is effective for the adjustment between viscosity and strength. That is to say, as the number of double bonds in the monomer increases, the intermolecular interaction becomes large and the viscosity increases. When the viscosity is raised, the alignment of molecules of the liquid crystalline compound takes time. On the other hand, if the number of double bonds is large, the strength of the obtained optical compensation film becomes high. By using two or more types of monomers, an appropriate viscosity and an appropriate strength can be easily achieved. The polyfunctional monomer having 4 or more double bonds in the molecule is preferably 20 to 80% by mass, more preferably 30 to 70% by mass based on the total amount of the monomers. A polyfunctional single system is added to the optically anisotropic layer together with the liquid crystalline molecules. The amount of the polyfunctional monomer to be added is preferably -80 to 200815875 0.1 to 50% by mass, more preferably 彳~2 〇 by mass relative to the liquid crystalline molecule. /〇. The composition for forming an optically anisotropic layer may contain at least one of a liquid crystal compound and, if desired, a photopolymerization initiator, a polymerizable monomer, and other additives as described above. The foregoing composition can also be prepared as a coating liquid. The solvent used in the preparation of the coating liquid is preferably an organic solvent. As the organic solvent, for example, (for example, hydrazine, hydrazine-dimethylformamide), argon (for example, dimethyl hydrazine), a heterocyclic compound (for example, pyridine), or a hydrocarbon (for example, Benzene, hexane), alkyl halides (eg, chloroform, dichloromethane), esters (eg, methyl acetate, butyl acetate), ketones (eg, acetone, methyl ethyl ketone), ethers (eg, Tetrahydrofuran, 1,2-dimethoxyethane). Among these, alkyl halides and ketones are preferred. Further, two or more organic solvents may be used. The coating liquid can be applied by a widely known method (for example, an extrusion coating method, a direct gravure coating method, a reverse gravure coating method, or a die coating method). It is preferred to use an alignment film in the formation of the aforementioned optically anisotropic layer. The alignment film has a function of orienting molecules of the liquid crystal compound in the above composition in a predetermined direction. It is common to use a polymer layer and a rubbed polymer layer on its surface. Also, an alignment film which produces an alignment function by providing an electric field, providing a magnetic field or light irradiation is known. The type of polymer used in the alignment film is determined by the alignment of the liquid crystal compound (especially the average tilt angle). For example, in order to horizontally align liquid crystallinity, a polymer (general alignment polymer) which does not lower the surface energy of the alignment film β is used. Regarding the specific poly-% 2 Μ _ ’, the matters described in the well-known literature on the liquid crystal cell or the optical compensation film can be widely used. In particular, in the case where the liquid crystal compound is formulated to be in a direction perpendicular to the rubbing treatment direction, for example, it is preferred to use the modification described in JP-A-2002-62427. Polyvinyl alcohol, the acrylic copolymer described in JP-A-2002-98836, and the polyimine and polylysine described in JP-A-2002-268068. Further, in order to further improve the adhesion between the alignment film and the optically anisotropic layer, it is preferred to use a polymer having a polymerizable group as a polymer for use in formation of an alignment film. The polymerizable group may be introduced by introducing a repeating unit having a polymerizable group or a substituent as a cyclic group into a side chain. It is more preferable to use an alignment film which forms a liquid crystal compound and a chemical bond at the interface, and such an alignment film can be, for example, those described in JP-A-9-52509. The thickness of the alignment film is preferably 0.01 to 5 μm, more preferably 0.05 to 2 μm. Further, after the molecules of the liquid crystal compound are aligned by using the alignment film, the molecules of the liquid crystal compound may be immobilized as they are in the alignment state to form an optically anisotropic layer, and only the optical anisotropic layer may be transferred. Printed on a polymer film. <<Optical anisotropic layer formed using a polymer material>> Further, the optically anisotropic layer may be a polymer layer formed by coating a polymer material. When a predetermined polymer material is used to prepare a coating liquid containing the same and applied to a surface of a polymer film or the like, the polymer is surface-aligned to exhibit a negative refractive index anisotropy and formed on the normal side of the film surface. An optically anisotropic layer having an optical axis in the direction. Specific examples of the polymer having such a property include -82 - 200815875, which is described in JP-A-2000-190385. A polymer material having at least one aromatic ring (polyamido' polyimine) , various polymers such as polyamine, polyester or polyester decylamine). In addition, in the process of forming the optically anisotropic layer by coating and drying, a polymerizable low molecular compound capable of providing such a polymer can be used to form a polymer. The optical compensation film according to the first aspect of the present invention may be incorporated in a liquid crystal display device as described above, or may be integrated with a polarizing film to form a polarizing plate as described below. It is incorporated in a liquid crystal display device. In the second aspect of the present invention, the in-plane hysteresis Re of the wavelength λ nm of the predetermined member X and the hysteresis Rth in the thickness direction are expressed as "Re; t (X)". And "Rth λ (X)". [Optical Compensation Film of Second Aspect] The second aspect of the present invention relates to an optical compensation film C of a C plate. The optical compensation film C of the second aspect of the present invention is preferably a negative C plate. Re55Q (C) is preferably 〇 ~ 10 nm, more preferably 〇 ~ 5 nm, more ideally 〇 ~ 3 nm. Further, Rth55G (C) is preferably 100 nm or more, more preferably 12 〇 to 28 〇 nanometer, and more preferably 160 to 220 nm. The optical compensation film C according to the second aspect of the present invention has a transparent support C1 and an optically anisotropic layer C2 supported by the transparent support C1. The transparent support C1 and the optically anisotropic layer C2 described above satisfy the following formulas (2 - 1) to (2-3), respectively. (2—1) 〇^ Re63〇(C1) ^ 1 0 -83- 200815875 (2—2) 0 SR e 5 5 ο (C 2) S 1 〇(2—3) 100^ Rth55〇(C2)- Rth55〇(C1) Since the transparent support C1 and the optically anisotropic layer C2 satisfy the above formulas (2 to 1) and (2-2), respectively, they do not substantially have an optical axis in the plane. On the other hand, since the transparent support C1 and the optically anisotropic layer C2 satisfy the above relationship (2 - 3), at least one of the optically isotropic layer C2 and the transparent support C1 is A positive or negative C plate holding the optical axis in the thickness direction. The optically anisotropic layer C2 and/or the transparent support C1 is preferably a negative C plate, and is desirably a negative C plate in which both the optically anisotropic layer C2 and the transparent support C1 are negative. Furthermore, the optical compensation film C of the second aspect of the present invention satisfies the following formula (2-4). (2—4) | Rth45〇(C2)/ Rth55〇(C2)- Rth45〇(C)/ Rth55〇(C) | ^0.1 Ratio of Rth at a wavelength of 450 nm and 550 nm (Rth45Q/Rth 5 5 0) is an indicator of the wavelength dispersion of the member. The Rth45Q/Rth55Q system of the component of the dispersibility is more than 1, and the Rth45Q/Rth550 of the member of the reverse dispersion is less than 1. Since the optical compensation film C and the optically anisotropic layer C2 of the second aspect of the present invention satisfy the above formula (2-4), the wavelength dispersion of the optical compensation film C is almost equal to the optical anisotropic layer C2. Wavelength dispersion. In the aspect of the C plate in which the transparent support C1 and the optically anisotropic layer C2 have substantially only a phase difference in the thickness direction, the Rth of the optical compensation film C of the laminate can be approximated by the sum of both Rths. Similarly, the wavelength dispersion (Rth45Q/Rth55〇) of the Rth of the optical compensation film C is also close to -84-200815875, which is similar to the wavelength dispersion calculated by the sum of Rths at both wavelengths, which is equivalent to considering C1. And the average load 値 of Rth55Q from the sign of the wavelength dispersion of C2 (Rth45Q/Rth55Q). That is, the contribution rates of C1 and C2 are almost determined by the individual Rth. In the case where the absolute 値 of the Rth of the transparent support C 1 is sufficiently small, the Rth of the optical compensation film C becomes almost equal to the optical by using the optical anisotropic layer C2 satisfying the above formula (2 - 3). Rth of the unidirectional layer C2. Therefore, in this aspect, the wavelength dispersion of the Rth of the optical compensation film C becomes a wavelength dispersion which is almost similar to the optical anisotropic layer C2 which accounts for more than half of the contribution of Rth. A negative C plate showing a high Rth ,, for example, can be produced by transferring a polymerizable liquid crystal composition into a predetermined liquid crystal phase and fixing the state. Further, it can be produced by coating and drying a coating liquid containing a predetermined polymer such as polyimine. The optically anisotropic layer produced by such a method becomes a negative C plate exhibiting a high Rth ,, and the wavelength dispersion of Rth exhibiting such an optically anisotropic layer is cis-dispersibility. In the second aspect of the present invention, the Rth of the optical compensation film and its contribution to the wavelength dispersibility are particularly large in comparison with the transparent support C1 due to the optical anisotropic layer C2. Therefore, a high Rth is exhibited, and a high Rth is exhibited by using the C plate in which the wavelength dispersion of Rth is dispersive as the optically anisotropic layer C2, and the wavelength dispersion of the Rth can be easily obtained. For the smooth dispersion of the C board. As described above, in the second aspect of the present invention, the polymer film used as the transparent support is used to produce a high refractive index, and the wavelength dispersion of -85 - 200815875 which exhibits the Rth is dispersive. The C plate is a difficult fact. In order to solve this problem, the optical compensation film is formed into a laminate of a transparent support C 1 composed of a polymer film and an optically anisotropic layer C2, so that a transparent support C1 can be obtained. The Rth of the page is also high, and the wavelength dispersion of the Rth is further increased by the Rth of the optically anisotropic layer C2 of the optical property of the dispersion. The optical compensation film according to the second aspect of the present invention is used in a liquid crystal display device, and particularly when used for optical compensation of a liquid crystal display device of a VA mode, color change and light generated with a viewing angle in black display can be reduced. leak. Further, in the second aspect of the present invention, since the contribution of the wavelength dispersibility of the Rth of the transparent support C1 is small, for example, even if Rth is used, the cellulose having a tendency to exhibit reverse dispersion tends to be deuterated or the like. It is also possible to provide an optical compensation film in which the wavelength dispersion of Rth is a display of dispersibility. Hereinafter, a better range of the optical characteristics of each member and a material used for production will be described in detail. [Optical Characteristics of Transparent Support C1 and Optically Isotropic Layer C2] The in-plane retardation Re of the transparent support C1 is preferably 0 to 10 nm, more preferably 0 to 5 nm, and more preferably 〇~3 Nai Meter. Further, the retardation Rth in the thickness direction is preferably from 25 to 100 nm, more preferably from -25 to 50 nm, and more preferably from 25 to 25 nm. The in-plane retardation Re of the optically isotropic layer C2 is preferably 0 to 10 nm, more preferably 〇 5 5 nm, more preferably 〇 3 3 nm. Further, the retardation Rth in the thickness direction is preferably from 100 to 300 nm, more preferably from 120 to 240 nm, and more preferably from 150 to 210 nm. In the second aspect of the present invention, it is preferable that both the transparent support C1 and the optically anisotropic layer C2 - 86 - 200815875 are negative C plates. Further, the wavelength dispersibility of Rth of the transparent support C1 may be either a cis-dispersibility or a reverse dispersion property. However, in the case of reverse dispersion, it is preferable that the degree of wavelength dispersibility is small. By. In fact, Rth4Q〇(C1) — Rth7〇Q(C1) is preferably -35 to 50, more preferably -25 to 25. On the other hand, the wavelength dispersion of the Rth of the optically anisotropic layer C2 is almost equal to the wavelength dispersion of the optical compensation film C, so that its preferable properties may follow the use of the optical compensation film (becoming an optical compensation film). The mode of the liquid crystal display device of the object is different, but generally it is preferably a disperser. For the optical compensation of the VA mode liquid crystal display device, Rth45Q(C2)/Rth55() (C2 It is preferably 1.04 to 1.30, more preferably 1.10 to 1.25. [Transparent Support C1] In the second aspect of the present invention, the transparent support C1 is preferably composed of a high molecular weight film. The material is not particularly limited as long as the optical characteristics required for the transparent support C1 are satisfied. For example, when the optical compensation film of the second aspect of the present invention is bonded to the polarizing film to perform polarizing plate processing, the polarizing plate is processed. Next, it is also necessary to have a function as a protective film for protecting the polarizing film. In this aspect, it is preferred to use a deuterated cellulose film, a cycloolefin polymer, a norbornene-based polymer, a lactone ring. Contains a polymer resin film or polycarbonate. In the second aspect of the present invention, as described above, since it is desired to obtain a transparent support having a sufficiently slanted dispersion, it is preferable to select a localized molecular film of R th which is a small seal. For the transparent support c1, the contribution of -87 - 200815875 to the Rth of the optical interpolation film C is suppressed as small as possible. The C plate having a small Rth値 is, for example, a deuterated cellulose film described in the column of 0043 to 0250 of JP-A-2002-3001, and the special opening 2002. - The polycarbonate-based film described in the publication No. 22,954, and the lactone ring described in the manual of WO 2006-1121, which is developed in recent years, contains a polymer-based resin film or the like. Polymer film. Among these, from the viewpoint of processing suitability of the polarizing plate, it is preferable to use a cellulose-based film, and the polymer resin film of the lactone ring has a low photoelastic coefficient, especially as a C plate. When the transparent support C1 is used, it is difficult to find excess in-plane retardation, which is preferable. [Optical anisotropic layer C2] The optically anisotropic layer C2 is preferably a C plate having a high Rth (at least Rth which is higher than the transparent support C1). The material is not particularly limited as long as it satisfies the optical characteristics required for the optically anisotropic layer C2, and may be an optically anisotropic layer composed of a polymerizable liquid crystal composition, or may be composed of a polymer. Optically anisotropic layer. The optically anisotropic layer of the C plate having a high Rth and a wavelength of Rth which is negative in dispersibility can be easily formed by using a polymerizable liquid crystal composition.

Not only a low molecular liquid crystalline compound as described above, but also a high molecular liquid crystalline compound can be used. As the rod-like liquid crystal compound capable of being fixed by polymerization, it is suitable to use a structure having a partial structure which can cause polymerization and crosslinking reaction by active light, electron beam, heat or the like. The number of structures in this portion is preferably 1 to 6, more preferably 1 to 3.

The polymerizable liquid crystalline compound and the polymerizable optically active (chi "a I" agent (disc liquid crystal compound) described in the column can be used for the formation of the optically isotropic layer C2. A benzene derivative described by Destrade et al. (Mol. Cryst, vol. 71, p. 111 (1981)) by C. Destrade et al. (Mol.

The aggregate of molecules or molecules is preferably a compound having rotational symmetry and capable of imparting a certain alignment. A preferred example is described in Japanese Laid-Open Patent Publication No. Hei 08-205-90-90-200815875. Further, the polymerization of a discotic liquid crystalline compound is described in JP-A-8-27284. The same is true for the rod-like liquid crystal compound. However, the optically anisotropic layer formed of the liquid crystalline composition containing the discotic liquid crystalline compound does not have to be a liquid crystalline compound in the optically anisotropic layer. For example, When a low-molecular liquid crystalline compound has a group that reacts with heat or light, the result is polymerization or crosslinking due to heat or photoreaction, and high molecular weight, thereby losing liquid crystallinity. In the process of producing the optically anisotropic layer C2, in order to make the direction in which the molecules of the rod-like liquid crystalline compound are directed substantially parallel (Re is substantially ◦ nanometer) on the layer, or in order to make the liquid crystalline compound The molecules are horizontally aligned, that is, the direction in which the disc-shaped molecules are directed is substantially perpendicular (Re is substantially 〇 nanometer) at the level, and it is preferable to have a repeating unit represented by the general formula (a) below.

The film thickness of the optically anisotropic layer C2 differs depending on the hysteresis of the object. However, in order to exhibit a certain degree of Rth値, it is preferably 〇5 μm or more. When a layer of 〇·5 μm or more is formed of the polymerizable liquid crystal composition, the adhesion to the transparent support C1 may be remarkably lowered. When the above-mentioned liquid crystal composition contains a polyfunctional monomer having a functional group of 2 or more, the adhesion between the optically anisotropic layer C2 and the transparent support C1 can be improved, which is preferable. The polyfunctional single system which can be used in the second aspect of the present invention is the same as the polyfunctional monomer which can be used in the above first aspect. The optically anisotropic layer C2 can prepare a polymerizable liquid crystal composition into a coating liquid, apply the coating liquid to the transparent support C1, dry it, and transfer it to a desired liquid crystal phase, and then, in the alignment state, The polymerization is fixed to form. The conditions which can be used for the preparation of the coating liquid, the polymerization initiator which can be added to the polymerizable liquid crystal composition, and the intensity of the UV light to be irradiated during polymerization can be referred to various materials and methods known in the art. The conditions and the like (for example, the materials and conditions described in JP-A-2005-173567, etc.) can be referred to. Further, in the formation of the optically anisotropic layer C2, an alignment film can be used to transfer the cholesterol phase and an alignment film which can be used in a vertical alignment direction. For example, it may be The alignment film described in the column of 0. 156 of JP-A-2005-49866. [Polymer for Optically Isotropic Layer C2] -93- 200815875 The optically anisotropic layer C2 serving as a C plate can also be formed by a polymer composition. For example, in the case where the polymer composition is formed into a film-like material to exhibit predetermined optical characteristics required for the optical anisotropic layer C2, it can be used as it is as the optically anisotropic layer C2.

For the polymerization of the discotic liquid crystalline compound, for example, the method described in JP-A-8-2728 84 can be employed. -97 - 200815875 The disc-like or liquid crystalline compound is preferably a polymerizable group which can be fixed by polymerization. For example, a structure in which a polymerizable group as a substituent is bonded to a disk-shaped core of a discotic liquid crystalline compound can be considered. Further, it is more preferable to have a structure in which a disc-shaped core and a polymerizable group have a linking group.

(D1) to (D15), (L1) to (L25), (Ρ1) to (Ρ1 8) ° exemplified, in the case of a discotic liquid crystalline compound having a polymerizable group, it is also obtained in the same manner as described above. It is essentially horizontally aligned. Specific examples of the discotic liquid crystalline compound in this case are, for example, more preferably disclosed on page 58 of the International Publication No. WO 08/8 857 4Α1, line 6 to page 65, line 8.

[Horizontal alignment agent] The composition for forming the optically anisotropic layer is preferably a "horizontal alignment agent" in addition to a dish-like liquid crystal compound. By including at least one "horizontal alignment agent" in the composition, the dish-shaped structural unit in the formed optically anisotropic layer can be substantially horizontally aligned with respect to the polymer film. In addition, the "horizontal alignment" in the present specification does not require that the long-axis direction of the disk-shaped liquid crystalline compound (that is, the disk surface of the core) be strictly parallel to the horizontal plane of the liquid crystal layer (for example, the liquid crystal layer is formed on the support body). In the case of the upper case, it is the surface of the support. In the present specification, the angle between the disk of the core and the horizontal plane is less than 10 degrees. The inclination angle is preferably 5 degrees or less, more preferably 3 degrees or less, more preferably 2 degrees or less, and most preferably 1 degree or less.

General formula (a) R2 R1

The definition of the general formula (a) and its preferred examples are the same as those of the first aspect described above. In the third aspect of the present invention, the amount of the "horizontal alignment agent" to be added is preferably from 0.01 to 20% by mass, more preferably from 0.05 to 10% by mass, based on the mass of the discotic liquid crystalline compound. Particularly preferred is 1.1 to 5 mass%. Further, the above-mentioned "horizontal alignment agent" may be used singly or in combination of two or more. [Immobilization of the alignment state of the liquid crystal compound] When the optically anisotropic layer is formed of a composition containing a liquid crystal compound, it is preferred to fix the aligned liquid crystal compound in an aligned state. The immobilization is preferably carried out by a polymerization reaction of a polymerizable group introduced into the liquid crystalline compound. The polymerization reaction is a photopolymerization reaction including a thermal polymerization reaction using a thermal polymerization initiator and a photopolymerization initiator, and more preferably a photopolymerization initiator. [Photopolymerization initiator] The photopolymerization initiator may, for example, be an α-carbonyl compound (the one described in the specification of US Pat. No. 2, 036, 670, No. 2,367, 670, US Pat. An ether (a substance described in the specification of U.S. Patent No. 24,488,828), an α-hydrocarbon-substituted aromatic aryl compound (the one described in the specification of U.S. Patent No. 272,251, 2), a polynuclear quinoline compound U.S. Patent No. 3,046, 127, U.S. Patent No. 2,951, 758, each of which is incorporated herein by reference in its entirety, the disclosure of the disclosure of the disclosure of U.S. Patent No. 3,354, s. (Athlete described in the above), acridine and phenanthridine compounds (the contents described in the specification of Japanese Patent No. 4,210, 856, U.S. Patent No. 4,239,850), and oxadiazole compounds (in U.S. Patent No. 4,221,970) The contents described in the specification). The optical compensation film according to the third aspect of the present invention is preferably produced by adding or subtracting the amount of ultraviolet light. However, in this case, a portion where light cannot be obtained in the thickness direction of the optically anisotropic layer may not be obtained. The polymerization for forming the optically anisotropic layer is performed uniformly. Therefore, in order to maintain uniform polymerizability in the thickness direction, the photopolymerization initiator is preferably one in which light absorption is in a long wavelength region and the diffusivity of the generated radical is high; more specifically, it is preferably A hydrocarbon radical having a photoreceptor range of from 330 nm to 450 nm and having a halogen radical or a number of atoms other than a hydrogen atom of 8 or less is used as a polymerization starting radical. The halogen radical, for example, may be a radical of fluorine, chlorine, bromine or iodine, and is preferably a chlorine radical. The hydrocarbon radical having 8 or less atoms other than the hydrogen atom may be a hydrocarbon radical having a substituent such as a halogenated hydrocarbon radical, and examples thereof are, for example, a methyl radical, an ethyl radical, Propyl radical, butyl radical, phenyl radical, tolyl radical, chlorophenyl free-101 - 200815875, bromophenyl radical, benzinyl radical, and the like. The matching of the light-sensing wavelength and the light source is necessary for high sensitivity. The photopolymerization initiator having a photoreceptor region of 330 nm to 450 nm has an advantage of not only matching well with a UV light source such as a metal halide lamp or a high-pressure mercury lamp, but also promoting polymerization of low-power UV light, and The optical compensation film has the advantage of less coloring. Further, as described above, when the bulk density of the radical of the photopolymerization initiator is small, the adhesion between the optically anisotropic layer and the alignment film becomes good. This is presumably because the polymerizable radical of the optically anisotropic layer having a small bulk density is diffused to the alignment film, so that a chemical bond is generated on the surface of the alignment film, and hardening occurs in the vicinity of the surface of the alignment film to improve the adhesion. Further, the photopolymerization initiator is preferably one which is more than 30% by energy of 1 〇〇 mJ/cm2. As an example of the photopolymerization initiator, as described below, the photopolymerization initiator which can be used in the third aspect of the invention is not limited to these.

[Polyfunctional monomer] A composition containing a liquid crystal compound for forming an optically anisotropic layer is preferably a polyfunctional monomer which is intended to have good adhesion to an alignment film to be described later. In the case where the optically anisotropic layer is formed with a lower amount of ultraviolet light than the normal one, the adhesion between the support which is the lower layer of the optically isotropic layer and the optically anisotropic layer is reduced, but When the optically anisotropic layer contains a polyfunctional mono-103 - 200815875 body having two or more functional groups, the adhesion which is easily deteriorated can be improved. The polyfunctional monomer which can be used is the same as the polyfunctional monomer which can be used in the above first aspect. In the case where the optically anisotropic layer is formed of a composition containing a liquid crystalline compound, it is preferred to form the composition on the alignment film by using the composition as a coating liquid. The solvent used for the preparation of the coating liquid is preferably an organic solvent.

[Alignment film] In order to align the liquid crystal compound, an alignment film is preferably used. Further, an alignment film which generates an alignment function by supplying an electric field, imparting a magnetic field or light irradiation is also known. The type of polymer used in the alignment film can be determined in accordance with the alignment of the liquid crystal compound (especially the average tilt angle). For example, in order to horizontally align the liquid crystalline compound, a polymer (generally a polymer for alignment) which does not lower the surface energy of the alignment film is used. Regarding the kind of the specific polymer, the matters described in the known literature on the liquid crystal cell or the optical compensation film can be widely used. In particular, in the case where the liquid crystal compound is aligned to a phase in which the phase is -104 to 200815875, which is perpendicular to the rubbing treatment direction, for example, it is preferable to use the modified poly group described in JP-A-2002-62427. The acryl-based copolymer described in JP-A-2002-98836, and the polyimine and polylysine described in JP-A-2002-268068. Among the alignment films, it is preferred to have a polymerizable group for the purpose of further improving the adhesion between the liquid crystalline compound and the polymer film substrate. The polymerizable group may be introduced by introducing a repeating unit having a polymerizable group into a side chain or a substituent as a cyclic group.

An aromatic polymer film such as a polyester polymer film or a polyfluorene system, or a deuterated cellulose film. However, when a deuterated cellulose film is used, the optical compensation film is used as a polarizing plate protective film. It is easy and therefore particularly desirable. Such a polymer film can be produced by a suitable method such as extrusion molding or cast film formation. Further, in the polymer film substrate of the third aspect of the present invention, a stretched film such as a double-105-200815875 axially stretched film may be used. The stretched film can be formed, for example, by stretching the above-prepared unstretched film by a roll longitudinal stretching method, a tenter transverse stretching method, and a biaxial stretching method. The stretching temperature is preferably in the vicinity of, or in the middle of, the glass transition temperature (Tg) of the film to be treated, and is less than Tg to less than the melting point.

The transparent protective film is usually supplied in a cylindrical form, and is continuously bonded in such a manner that the long axis direction coincides with the long polarizing film. Here, the alignment axis (slow phase axis) of the protective film may be any direction, but the alignment axis of the transparent protective film is preferably parallel to the long axis direction in terms of ease of operation. Further, the angle between the slow axis (alignment axis) of the transparent protective film and the absorption axis (tensile axis) of the polarizing film is not particularly limited, and can be appropriately set in accordance with the purpose of the polarizing plate. Further, in the case where the polarizing film is produced by using a uniaxial stretching type tenter stretching machine in the width direction, it is preferable to make the slow axis (alignment axis) of the transparent protective film and the absorption axis of the polarizing film (stretching) The axes are laminated substantially orthogonally. The Re値 of the transparent protective film is, for example, preferably at least 63 nm at 632.8 nm, more preferably at most 5 nm.

The optical compensation film and the polarizing film described above are preferably fixed by an adhesive from the viewpoint of preventing the deviation of the optical axis from -108 to 200815875 and preventing the invasion of foreign matter such as dirt. Specifically, the surface of the polarizing film and the surface of the optical compensation film (polymer film) are preferably adhered by an adhesive or adhered via an adhesive layer. The type of the adhesive is not particularly limited, and from the viewpoint of preventing the change in the optical characteristics of the constituent members, it is preferable that the processing is not required at the time of curing and drying in the adhesive treatment, and it is desirable that the processing is not performed. It takes a long time to harden and dry. From such a viewpoint, it is preferred to use a hydrophilic polymer-based adhesive or an adhesive layer.

Polarizing plates 1 and 14 It may also be a slow phase axis 102 and 106 parallel to the protective films 1〇1 and 105, and an absorption axis 104 of the polarizing plate-111-200815875, because when it is in such a configuration relationship, the size and curl of the polarizing plate It is preferable that it is a polarizing plate having high mechanical stability, and it is preferable that at least two axes composed of three films, for example, a retardation axis of a protective film on one side and an absorption axis of a polarizing film, or When the retardation axes of the two protective films are substantially parallel, the same effect can be obtained. In Fig. 1, the optically anisotropic layer 3 is constituted by an optically uniaxial or biaxial phase difference plate, and is not particularly limited, however, for example, it may be a lowering A polymer, a polycarbonate polymer, a polyallyl polymer, a polyester polymer, or a polymer obtained by mixing two or more of the above polymers. Among these, it is preferred that the birefringence property is excellent in controllability, transparency, and heat resistance. The optically isotropic layer 3 is preferably biaxial. The optically anisotropic layer 3 preferably satisfies the following formulae (8) and (9), and more preferably exhibits wavelength dispersion of the following formula (10). Equation (8) 70 ^ Re (550) ^ 180 Equation (9) 30 ^ Rth(550) ^ 140 Equation (10) 0.7^ Re(450)/Re(550)^ 1.0 On the other hand, the optical anisotropic layer 10 is an optically anisotropic layer having the optical compensation film of the present invention. Preferably, it is a layer which does not substantially have an optical axis in the plane, has an optically negative refractive index anisotropy, and has an optical axis perpendicular to the layer plane. The absolute 値 of the refractive index anisotropy is preferably 0.060 to 0.085, and the in-plane retardation Re is preferably 10 to 10 nm. The optically anisotropic layer 1 is preferably formed of a layer formed by a cholesteric liquid crystal phase of a rod-like liquid crystal compound and a horizontal alignment of a molecule of a discotic liquid crystal compound of -112 to 200815875 (vertical alignment). A layer or a layer formed by coating a predetermined polymer material. The optically anisotropic layers 3 and 10 cancel the image coloration of the liquid crystal cell and impart a wide viewing angle. Further, the liquid crystal display device of Fig. 1 has an example of optically anisotropic layers 3 and 10 which are individually one layer, but may have two or more optically anisotropic layers 3 and 10. In the first diagram, when the observer side is the upper side, the configuration shown in Fig. 1 is such that the optical anisotropic layer 3 is the polarizing plate 1 and the viewer-side liquid crystal cell substrate 5 disposed on the observer side. The optically anisotropic layer 10 is disposed between the polarizing plate 14 and the back side liquid crystal cell substrate 8 disposed on the back side; however, the optical anisotropic layer 3 and the optical anisotropic layer 10 may be interchanged. The composition. Further, both of the optically anisotropic layers 3 and 10 may be disposed between the polarizing plate 1 and the viewer-side liquid crystal cell substrate 5 disposed on the observer side, or may be polarized light disposed on the back side. Between the plate 14 and the back side liquid crystal cell substrate 8. Further, the optically anisotropic layer 3 may be integrated with the polarizing plate 1 or may be incorporated in the liquid crystal display element in a state of being integrated with the polarizing plate 1. For example, the optically anisotropic layer 3' may be formed of a polymer film and have a function as a protective film on the side of one of the polarizing films. Further, in the case where the optically isotropic layer 3 is a layer formed of a liquid crystal composition, it is also possible to have a protective film 2 function as a side supporting one of the polarizing films. In the latter case, for example, an integrated polarizing plate in which a transparent protective film 'polarizing film, a transparent protective film (also serving as a transparent support), and an optically anisotropic layer β-spray are laminated is preferably used. In the case where the above-mentioned integrated polarizing plate-113-200815875 is incorporated in the liquid crystal display element, it is preferably from the outer side of the device (away from the side of the liquid crystal cell), in accordance with the transparent protective film, the polarizing film, and the transparent protection. The film (and the transparent support) and the optically anisotropic layer 3 are sequentially assembled. In the case of producing an integrated polarizing plate, it is preferred to use a retardation axis of the optically anisotropic layer 3 (or a laminate supporting the support and the optically anisotropic layer 3) and a laminated film. The absorption axis is attached slightly vertically. As described above, the optically anisotropic layer 1 一部分 is a part of the optical compensation film of the present invention. Similarly to the above-described optically isotropic layer 3, the optically anisotropic layer 10 can be incorporated in a liquid crystal display element as an integrated polarizing plate integrated with a polarizing plate 14. In the aspect in which the optically anisotropic layer 1 is a layer formed of a composition containing a liquid crystalline compound, the protective film on one side of the polarizing plate 14 may be a support of the optically anisotropic layer 10 Polymer film. In such an aspect, it is preferred to form an integrated polarizing plate in which a transparent protective film, a polarizing film, a polymer film, and an optically anisotropic layer are laminated in the order of the transparent polarizing film, and the integrated polarizing plate is formed. The plate is incorporated into the liquid crystal display device from the outside (away from the side of the liquid crystal cell) in the order of the transparent protective film, the polarizing film, the polymer film, and the optically anisotropic layer. The liquid crystal cell of the liquid crystal display device of Fig. 1 is preferably in a vertical alignment mode (VA mode). The liquid crystal cell of the VA mode has a liquid crystal layer formed by sealing a liquid crystal molecule 7 having a negative dielectric anisotropy between the upper and lower substrates 5 and 8 which have been rubbed on the opposite surface. For example, liquid crystal molecules of Δ η = 0· 08 13 and Δ - 4·6 can be used to produce a liquid crystal cell in which the orientation direction of the liquid crystal molecules (i.e., the tilt angle) is about 89°. At this time, the thickness d of the liquid crystal layer can be set to about 3.5 μm. The brightness of the white display varies depending on the thickness d (nano) of the liquid crystal layer and the product Δ η · d of the refractive index anisotropy Δη of -114-200815875. In order to obtain maximum brightness, the thickness d of the liquid crystal layer is preferably in the range of 2 to 5 μm (2000 to 5000 nm) and Δη is in the range of 0.060 to 0.085. Here, the refractive index anisotropy Δ η represents Δ n = Rth / film thickness (nano). A transparent electrode (not shown) is formed on the inner side of the substrate 5 and the substrate 8, but the liquid crystal molecules 7 in the liquid crystal layer are aligned to be vertically perpendicular to the non-driving state in which the driving voltage is not applied to the electrodes. On the faces of the substrates 5 and 8, as a result, the polarization state of the light passing through the liquid crystal panel hardly changed. As described above, since the absorption axis 2 of the upper polarizing plate 1 of the liquid crystal cell and the absorption axis 15 of the lower polarizing plate 14 become slightly vertical, the light does not pass through the polarizing plate. That is, the liquid crystal display element of Fig. 1 is in a black state in a non-driving state. On the other hand, in the driving state, the liquid crystal molecules are inclined in a direction parallel to the substrates 5 and 8, and the light passing through the liquid crystal panel changes the polarization state due to the tilted liquid crystal molecular weight, and passes through the polarizing plate, i.e., becomes a white state. The VA mode is characterized by high speed response and high contrast. However, the contrast may be low in the front and low in the oblique direction. The liquid crystal molecules in the black display are vertically aligned to the substrate surface. When viewed from the front, since the liquid crystal molecules have almost no birefringence, the transmittance is low and high contrast is not obtained. However, in the case of observing from an oblique direction, liquid crystal molecules undergo birefringence. Further, the angle of intersection of the upper and lower polarizing plates absorbs the axis, which is a right angle of 90° from the front, but is greater than 90° when viewed obliquely. Due to these two factors, light leakage tends to occur in the oblique direction, and the contrast tends to decrease. Further, in the case where the liquid crystal cell is birefringent and observed in an oblique direction in the black state, the color taste -115 - 200815875 is changed. In the present invention, in order to solve such problems, an optical compensation film (10 in Fig. 1) of the present invention comprising a polymer film satisfying predetermined optical characteristics and an optically anisotropic layer is disposed. Further, in the liquid crystal display device of Fig. 1, since the uniaxial or biaxial optical anisotropic layer 3 is disposed, it is possible to reduce light leakage or the like in the oblique direction in the black state. In Fig. 1, there is shown an example in which a liquid crystal material having a negative dielectric constant such that the liquid crystal molecules 7 are vertically responsive to the direction of the electric field due to an electric field applied between the upper and lower substrates 5 and 8 is used. Further, in the case where an electric field is applied to the substrate on the one side of the electrode and in the lateral direction parallel to the substrate surface, a liquid crystal material having a positive dielectric constant anisotropy can be used. Further, in the liquid crystal display device of the VA mode, although the addition of the filter material used in the Twisted Nematic mode liquid crystal display device is generally used, the dynamic response characteristics are deteriorated and are rarely used, but there are also Reduce the addition of poor alignment. In the VA mode, the liquid crystal molecules are obliquely aligned in the white display, but in the opposite direction to the oblique direction, the magnitude of the refraction of the liquid crystal molecules when viewed from the oblique direction is different, and the difference in brightness and hue is generated. In order to solve this, the liquid crystal cell is preferably a complex field (m u 11 i d 〇 m a i η ). The so-called complex field means that a plurality of fields having different alignment states are formed in one pixel. For example, among the liquid crystal cells of the VA mode of the complex field mode, there are a plurality of fields in which one pixel has different inclination angles of liquid crystal molecules when an electric field is applied. Among the liquid crystal cells of the VA mode of the complex field mode, the tilt angle of the liquid crystal molecules caused by the application of the electric field can be averaged for each pixel, whereby the viewing angle characteristics can be averaged. In the single pixel -116-200815875, the splitting is upward, and the unevenness of the electric field density is maintained by providing slits on the electrodes, setting protrusions, and changing the direction of the electric field. This number of divisions can be increased to obtain an equal angle of view in all directions. Further, at the boundary of the domain of the alignment division, the liquid crystal molecules are difficult to respond. Therefore, in the normal block display, the brightness is lowered due to the black display. Adding a filter to the liquid crystal material will cause the boundary area to shrink. The liquid crystal display device of the present invention is not limited to the configuration shown in Fig. 1, and may include other members. For example, a color filter may be disposed between the liquid crystal cell and the polarizing film. Moreover, in the aspect of the transmissive liquid crystal display device, the backlight may be disposed on the back surface with a cold cathode or a hot cathode fluorescent tube, or a light emitting diode, a field emission element, and an electroluminescent element as a light source. . On the other hand, in the reflective liquid crystal display device, one polarizing plate may be disposed only on the observation side, or a reflective film may be provided on the back surface of the liquid crystal cell or the inner surface of the liquid crystal cell lower substrate. Needless to say, it is of course possible to provide frontlight on the viewing side of the liquid crystal cell using the aforementioned light source. Further, a semi-transmissive type in which a transmissive portion and a reflecting portion are provided in one pixel of the display device may be used. The type of the liquid crystal display device of the present invention is not particularly limited, and includes any liquid crystal display element of any of an image direct view type, a video projection type, and a light modulation type. In the present invention, it is particularly effective to apply an active matrix type liquid crystal display device using a 3-terminal or 2-terminal semiconductor element such as T F T or Μ丨Μ. Needless to say, it is of course also possible to effectively apply a passive matrix type liquid crystal display device represented by the super twisted nematic type (Super Twisted Nematic type, STN type) as a representative of 200815875, which is called time division driving.

At this time, although the adhesion is deteriorated as the UV irradiation amount is lowered, when the photosensitive field is used, it is 330 nm to 450 nm. Production When the halogen radical is used as the polymerization initiator A, it is difficult to cause deterioration of adhesion. Therefore, in order to increase Rth/d, it is preferred to use a photosensitive region of 330 nm to 450 nm to generate halogen free. Base polymerization initiator A.

Further, from the comparison of F71 to F74 and F81 to F84, when the irradiation amount of UV-182-200815875 is reduced, Rth/d can be increased. In this case, the adhesion tends to deteriorate as the amount of UV irradiation decreases. However, a polyfunctional monomer having a tetrafunctional or higher polymerizable group is used as the polyfunctional monomer (F71 to F74). It is also difficult to cause deterioration in adhesion than those using a trifunctional polyfunctional monomer (F81 to F84). Therefore, in order to increase Rth/d, a preferred embodiment is to use a polyfunctional monomer having a tetrafunctional or higher polymerizable group.
