The high-fiber acid is used for the directionality of the optical light such as B. For example, the polarizing plate is usually made of cellulose acetate film. On the other hand, an optical compensation sheet (phase difference film) of a liquid crystal display device or the like is inversely required to have an optical anisotropy (high hysteresis 。). Therefore, an optical compensation sheet is usually made of a polycarbonate film or a polyimide film. Recently, there have been proposals (for example, Patent Documents 1 and 2), and it has been disclosed that a cellulose acetate film having an ilj hysteresis can be used for optical anisotropic applications. 2 In order to achieve 1% hysteresis by means of a cellulose acetate film, an aromatic compound having at least two aromatic rings is added, and a compound having a 1,3,5-three-till ring is also added to carry out elongation treatment. A polymer material in which cellulose is not easily stretched is known to be less likely to increase its optical anisotropy, but the above-mentioned Patent Documents 1 and 2 have an additive, In order to reduce the optical anisotropy of the liquid crystal display device and reduce the manufacturing cost, it is necessary to form a thin film of the liquid crystal cell. In the optical film mainly composed of the optical compensation sheet, the optical anisotropy which can be realized by the compound of the 3,5_three-till ring described in the above Patent Documents 1 and 2 (Re: hysteresis in the film surface, Rth: hysteresis in the thickness direction of the film), the step is required to have a higher Re and a lower Rth. However, the inventors of the present invention concentrate on reviewing the results of the methods disclosed in Patent Documents 1 and 2 'clearly This method is problematic in that the above Re値 and Rth値 are controlled within their respective preferred ranges. Therefore, it is necessary to develop a new optical performance control technique.

The cellulose derivative film of the present invention can also be extended. In order to exhibit optical anisotropy, it is particularly preferable to be able to extend at an arbitrary magnification. The stretching can be carried out by a well-known method, for example, a temperature from a high temperature of 10 ° C higher than the glass transition temperature (Tg) of the cellulose derivative film to a high temperature of 50 ° C, which can be uniaxially stretched by a tenter. Method, synchronous biaxial stretching method, successive biaxial stretching method, blow molding method to extend. Further, when the film is produced by the solution casting method, the residual solvent is in the range of 1 to 30%, more preferably in the range of 5 to 20%. The stretching ratio is preferably 1 to 2 times. The cellulose derivative film can be surface-treated as appropriate to achieve adhesion of the cellulose-derived film to each functional layer (e.g., undercoat layer and back layer). For example, luminescent discharge treatment, ultraviolet irradiation treatment, corona treatment, flame treatment, acid or alkali treatment can be used. The illuminating discharge treatment referred to herein may be a low-temperature plasma produced under a low pressure gas of 1 〇 3 to 20 Torr (0.133 Pa to 2.67 kPa), or may be a plasma treatment under a large gas. The plasma-excited gas system refers to a gas which is excited by the plasma under the above conditions, and examples thereof include argon, nitrogen, helium, neon, krypton, nitrogen, carbon dioxide such as fluorine of tetrahydrofuran, and the like. In this regard, it is described in detail on pages 30 to 32 of the Inventor's Open Technical Bulletin (public technology number 2001-1745' issued March 15, 2001 'Invention Association'). The plasma treatment under atmospheric pressure, which is closely noticed, is, for example, at 10 to 1 〇〇〇 keV, using an irradiation energy of 20 to 500 kGy, more preferably 30 to 500 keV, using an irradiation energy of 20 to 3 00 kGy. Among these, it is particularly preferable that the saponification treatment is extremely effective as the surface treatment of the 醯-76 - 1378120 cellulose film. The saponification treatment is carried out by immersing the surface of the film in an alkali solution, followed by liquid neutralization, circulating water washing and drying. The alkali solution may be a potassium hydroxide solution, a sodium hydroxide solution or the like, and the range of the concentration of the hydroxide ion is preferably ～5.0 mol/liter, and is preferably from 0.5 to 4.0 m/liter. The temperature of the alkali solution is preferably in the range of room temperature to 90 ° C, more preferably in the range of 40 °.

In order to apply the saponified liquid to the transparent support, the solvent of the soap coating liquid preferably has wettability, and it is preferred that the coating liquid is treated with a solvent to form irregularities on the surface of the transparent support and to have a good surface shape. Specifically, an alcohol solvent is preferred, and it is preferably excellent. Further, an aqueous solution of a surfactant may be used as the base of the solvent coating liquid, preferably dissolved in the above-mentioned alkali, and more preferably KOH. The pH of the saponified coating liquid is preferably 10 or more, and the reaction conditions of the saponified coating liquid of 1 2 or more are preferably 1 second or longer and 5 minutes at room temperature, more preferably 5 seconds or longer and 5 minutes or shorter, and more preferably 20 seconds or longer. The next is especially good. After the saponification reaction, it is preferably washed with water or washed with an acid washing soap. Further, the coating saponification treatment and the arrangement described later can be continuously performed, and the number of steps can be reduced. In order to achieve the adhesion of the film to the functional layer, the surface is acid-dissolved, and the saponification can be maintained by the cloth method of the coating method of 0.7%. Saponification and NaOH I are better. The following is the method of applying the chemical solution to the film-coating point -77 - 1378120. After the treatment, the method is applied directly to the cellulose derivative film to coat the functional layer to obtain the adhesion, and after performing a certain surface treatment. It is a method in which an undercoat layer (adhesive layer) is provided without a surface treatment, and a functional layer is coated thereon. The details of these undercoat layers are described in detail on page 32 of the Inventor's Association Technical Bulletin (public technology number 2001-1 74 5, March 15, 2001 issue, invention association). Further, regarding the functional layer of the deuterated cellulose derivative film of the present invention, various functional layers are disclosed in the Invention Association (Technical No. 2001-1 74 5, issued on March 15, 2001, Invention Association) Pages 3 2 to 4 5 are described in detail. In order to control Re値 and Rth値 of the deuterated cellulose derivative film of the present invention in respective preferred ranges, it is preferred to appropriately adjust the general formulae (1) to (5) and (4-A) to be used. a compound represented by any one of (4-B), (5-A), (5-B), (11) to (13), (14-A) or (14-B) (hysteresis oxime controlling agent) The type and amount of addition, and the extension of the film. In particular, in the present invention, by selecting a hysteresis controlling agent capable of achieving a desired Rth, and appropriately setting the amount of the hysteresis controlling agent and the stretching ratio of the film to obtain a desired Re, it is possible to obtain a desired Re Rth 醯 醯 纤维素 cellulose derivative film. In the present specification, ReU) and Rth(A) each indicate hysteresis 波长 in the wavelength A plane and hysteresis 厚度 in the thickness direction. Re ( λ ) is measured by a KOBRA 2 1 ADH (manufactured by Oji Scientific Instruments Co., Ltd., trade name) to direct the light of the wavelength λ nm into the normal direction of the film. Rth(λ) is the incident wavelength λ Nai from the above-mentioned Re(λ), the in-plane slow phase axis (determined by KOBRA 21ADH) as the tilt axis (rotation axis)' from the oblique direction of +40 degrees with respect to the film normal direction. -78- 1378120 meters of light, the measured hysteresis 値, and the slow phase axis within the axis as the tilt axis (rotation axis), from the oblique direction of the film normal direction - 40 degrees oblique direction of the incident wavelength λ nm light, The hysteresis 値 'average refractive index assumed by the measurement of the hysteresis measured in three directions was measured, and the incident film thickness 値 was calculated based on KOBRA 21ADH. Here, the assumption of the average refractive index can be achieved by using "polymer handbook" (JOHN WILEY & SONS, INC) and a catalogue of various optical films. If the average refractive index is not known, it can be measured using an Abbe refractometer. The average refractive index of the main optical film is as follows: deuterated cellulose (1.48), cycloolefin polymer (1.52), polycarbonate (1.59), polymethyl methacrylate (1.49), polystyrene (1.59). ). First, the use of the deuterated cellulose derivative film of the present invention will be briefly described. The cellulose-derivative cellulose derivative film of the present invention is used as an optical film, particularly a polarizing plate protective film film, an optical compensation film (also referred to as a retardation film) of a liquid crystal display device, an optical compensation sheet of a reflective liquid crystal display device, or a silver halide. Photographic materials are useful for support systems. Therefore, the thickness of the film of the present invention is not particularly limited depending on such applications, and it is preferably 30 μm or more, more preferably 30 0 to 200 μm. When a protective film for a polarizing plate is used, the method for producing the polarizing plate is not particularly limited, and it can be produced by a usual method. The method of subjecting the obtained cellulose derivative film to alkali treatment, using a fully saponified polyvinyl alcohol aqueous solution, and bonding the two sides of the polarizer prepared by immersing the polyvinyl alcohol film in an iodine solution can also be carried out. For example, the special adhesive processing described in each of the Japanese Patent Publication No. 6-94915, -79-1378120, and No. 6- 1 1 82 3 2 is used instead of the alkali treatment. In order to adhere the adhesive to the protective film-treated surface and the polarizer, a polyvinyl alcohol-based adhesive such as polyvinyl alcohol or polyvinyl butyral or a vinyl latex such as butyl acrylate may be mentioned. The polarizing plate is composed of a polarizer and a protective film which protects both surfaces thereof, and has a protective film on the surface of the polarizing plate and a protective film on the opposite side. The purpose of the protective film and the release film is to protect the polarizing plate when the polarizing plate is shipped, when the product is inspected, and the like. At this time, the pellicle film is bonded for the purpose of protecting the surface of the polarizing plate, and is used to adhere the opposite side surface of the surface of the polarizing plate to which the liquid crystal panel is bonded. Further, the use of the release film is for the purpose of covering the adhesive layer of the liquid crystal panel, and is used for the surface of the polarizing plate to which the liquid crystal panel is bonded. In the liquid crystal display device, a substrate containing a liquid crystal is usually disposed between two polarizing plates, and a polarizing plate protective film of the film of the present invention is applied, and excellent display properties can be obtained in any part. In particular, the polarizing plate protective film on the display surface of the liquid crystal display device is particularly preferable because it is provided with a transparent hard coat layer, an antiglare layer, an antireflection layer, or the like. The cellulose derivative film of the present invention can be used in a wide variety of applications, and is particularly effective as an optical compensation sheet for a liquid crystal display device. The cellulose derivative film (deuterated cellulose film) of the present invention can be used for liquid crystal cells of various display modes.

Further, there has been proposed a mode in which the display mode is divided and aligned. The cellulose derivative film is effective for use in a liquid crystal display device of any of the display modes. Further, it is also effective for use in any of liquid crystal display devices of the transmissive type, the reflective type, and the semi-transmissive type. The cellulose derivative film of the present invention can be used as a support of an optical compensation sheet for a TN type liquid crystal display device having a liquid crystal cell of a TN mode. The cellulose derivative film of the present invention can also be used as a support for an optical compensation sheet in an STN type liquid crystal display device having a liquid crystal cell of an STN mode. Generally, the rod-like liquid crystal molecules in the liquid crystal cell of the 'S TN type liquid crystal display device are distorted in the range of 90 to 360 degrees, and the refractive index of the rod-like liquid crystal molecules is different in the directivity (Δη) and the liquid crystal cell gap (d). The product (Δ nd) is in the range of 300 to 1500 nm. The optical compensation sheet used in the STN type liquid crystal display device is described in Japanese Laid-Open Patent Publication No. 2000-1 053. The deuterated cellulose film of the present invention is particularly advantageous in use as a support system for an optical compensation sheet used as a VA type liquid crystal display device having a liquid crystal cell of a VA mode. The cellulose derivative film of the present invention is particularly advantageous for use as a support system for an optical compensation sheet used for a liquid crystal cell having a 0CB mode, a CB type liquid crystal display device, or a HAN type liquid crystal display device having a liquid crystal cell of an η AN mode. . The cellulose derivative film of the present invention is also used as an optical compensation sheet of a reflective liquid crystal display device of the TN type, the STN type '1 1378120 HAN type, and the GH (Guest-Host) type. These display modes are known in the past. The TN-type reflective liquid crystal display device is described in each of the publications of Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. An optical compensation sheet used in a reflective liquid crystal display device is described in WOOO-65384. The fiber derivative film of the present invention is also advantageously used as a support for an optical compensation sheet of an ASM type liquid crystal display device having a liquid crystal cell of an ASM (Axially Symmetric Aligned Microcell) mode. The liquid crystal cell of the ASM mode is characterized in that the thickness of the liquid crystal cell is maintained by a resin spacer which can be adjusted in position. Other properties are the same as those of the TN mode. The liquid crystal cell and the ASM type liquid crystal display device of the ASM mode are described in Kume et al. (Kume et al., SID 98 Digest 1089 (1998)). The use of the above-mentioned detailed cellulose derivative film is described in detail on pages 45 to 59 of the Inventor's Association Technical Bulletin (public technology number 2001-1745, March 15, 2001 issue, invention association). .
