[Prior Art] An optical member such as a liquid crystal display device, for example, a polarizing plate or a phase difference plate, is attached to a liquid crystal element using an adhesive. Usually, it is an adhesive optical member in which an adhesive layer is laminated on an optical member. Since the optical member has a large degree of expansion and contraction under the condition of heating or humidification, it is easy to cause lifting or peeling after the attachment. Therefore, the adhesive for optical members is required to have a long-term response under heating or humidification conditions. Further, an adhesive optical member such as a crucible is usually formed integrally with a release liner to which an anthrone is removed, and exhibits smoothness. The release liner of the adhesive optical member is used for precision coating on a ruthenium (polyethylene terephthalate) film because it is excellent in transparency, heat resistance, smoothness, and appearance defects. A release liner formed by a ketone.

In the method of adjusting the above-mentioned peeling force to an appropriate size, for example, a method of changing the amount of use of the anthrone component has been proposed (for example, refer to Patent Document No. 2 and Patent Document 2). However, if a peeling force is adjusted by using, for example, a heavy release agent or the like in the fluorenone component, the heavy release agent may be transferred onto the adhesive face to cause a decrease in adhesive properties. Further, it is known that when the anthrone release liner is wound around the original sheet, the heavy release agent is transferred to the back surface, which causes a defect when the release liner is peeled off. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2000-199199. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for adjusting the peeling force of an anthrone release liner.

According to the method for adjusting the peeling force of the fluorenone release liner of the present invention, as shown in the results of the examples, the base polymer and the peroxide adhesive composition layer are provided by using the release treatment surface contained in the fluorenone release liner. The peeling force of the fluorenone release liner can be easily adjusted by the process and the peeling force adjustment method of the fluorenone release liner which partially or completely heat-decomposes one of the above-mentioned peroxides. The detailed reason for the peeling force of the liner can be easily adjusted by the above adjustment method. Although the detailed reason for the peeling force of the liner is not clear, it is presumed that the thermal radical decomposition of the peroxide in the adhesive composition generates active radicals, so that the anthrone molecule Dehydrogenation occurs in the process, resulting in denaturation of the oxime surface. In the method for adjusting the peeling force of the above-mentioned anthrone release liner, it is preferred that the above-mentioned adhesive composition lg is heated and decomposed. The peel force can be adjusted by adjusting the amount of peroxide to exhibit an appropriate peel force. The method for producing the ketone ketone release liner adhesive layer of the present invention comprises the process of providing a base polymer and an adhesive composition layer of the over 8 7 582821 = compound on the release treatment surface of the fluorenone release liner. The adhesive layer manufacturing method, the sister contains a process for adjusting the peeling force of the anthrone release liner. By using the "manufacturing", an adhesive layer for an optical member excellent in durability and having a peeling force can be obtained. In the method for producing the pressure-sensitive adhesive layer, the base polymer of the pressure-sensitive adhesive composition preferably contains (meth)acrylic acid in an amount of 80 parts by weight or more per 100 parts by weight of the monomer. Dilute acid polymer. By using the dot composition, an adhesive layer for an optical member excellent in durability and having a moderate peeling force can be obtained. Further, in the method for producing the above-mentioned pressure-sensitive adhesive layer, 1 part by weight of the adhesive composition may contain 1 part by weight of the money coupling agent G.G. By using the adhesive composition, an adhesive layer for an optical member excellent in durability and having a moderate peeling force can be obtained. On the other hand, the method for producing an anthraquinone release liner adhesive sheet of the present invention comprises a process for providing an adhesive composition layer containing a base polymer and a peroxide on a peeling treatment surface of a Shi Xigang release liner. It is characterized in that the peeling force of the Shi Xiying release liner is adjusted to a range of 〇1 to 〇4ν/5〇_ by a process of thermally decomposing part or all of the peroxide. By using this production method, it is possible to obtain an anthraquinone release liner-adhesive sheet which is excellent in durability and has a moderate peeling force. Further, the adhesive layer for an optical member of the present invention is produced in accordance with the above method. Since the pressure-sensitive adhesive layer of the present invention can function as described above, it is possible to obtain an adhesive sheet for an optical member which is excellent in durability and has a moderate peeling force by using the pressure-sensitive adhesive layer of the present invention. Therefore, it is particularly suitable for the 8 8 1375821 peeling type adhesive layer β. The optical member used in the present invention is formed by forming a release sheet on the adhesive layer. According to the light of the present invention, the second film is used for the purpose of exhibiting the above-mentioned effects, and the optical member for the optical member having excellent long-term durability and moderate peeling force is attached to the sword optical member.

The release treatment surface of the release ketone release liner of the ketone release liner of the present invention contains .... It is included in the process of setting up the layer of the adhesive layer of the base polymer and peroxide, and the process of decomposing all the other parts of the peroxide. Invention#Reagent composition layer< In the process, the dispersing solvent of the composition of the agent is applied, and the coating is applied to the hot melt coating. However, in order to improve the coating, it is preferred to use a dispersing solvent. The dispersion solvent is not particularly limited. For example, an organic solvent such as toluene, B =, an alcohol or an organic compound, water or the like can be suitably used. It may be applied directly to the solvent used in the polymerization, or may be appropriately added. Each of the agents such as 5H may be used singly or in combination of two or more. For example, "Adhesive Handbook (2nd Edition), 174th Stomach, Adhesive Tape Industry Association" '1995.10.12' shows the use of a condensation reaction type ketone stripping agent (for example, 'generally has a hydroxyl group at both ends Polydimethyl methoxy oxime as a base polymer, polymethyl hydride dioxime as a cross-linking agent, kicking oxime as a catalyst, and addition reaction type ketone stripping agent (for example, Generally, a part of the methyl group in the polydimethyl oxalate which has a trans-group is substituted into a base-based polymer, and a polymethyl-methadiene is used as a cross-linking agent to a platinum system. The catalyst is a catalyst and an addition reaction type ketone stripper. However, the present invention is not particularly limited, and any release liner of a release agent may be used. The peroxide of the present invention can be used as long as it can generate active radicals by heating and react with the ketone of the release liner, but it is preferable to use the one-minute half-life temperature as the ribs. It is better to use a peroxide having a one-minute half-life temperature of 90 to 140 〇c.

Moreover, the adhesive composition layer formed on other substrates may also be used. In the peeling force adjustment method of the present invention, in addition to adjusting the amount of peroxide, the decomposition treatment temperature and the decomposition treatment time are also important factors. In the present invention, the amount of peroxide decomposition, the aforementioned adhesive composition Ig, preferably adjusted to 1~2"m〇b is preferably 2~16"mob to 2~12" and preferably. If the decomposition amount of peroxide is lower, the peeling force will become too small, If it is higher than 2" mol, the peeling force may become too large, so it is not good. = The peroxide is more than 2 parts by weight of the adhesive composition (10 parts by weight). If it is lower than .2, the peeling force of the heavy separator may become too small. On the other hand, if it is higher than 2 parts, the peeling force will be too large, or the adhesive layer will be too large. In the middle of the night, the peroxide changes the adhesion characteristics with time.

Adhesive composition The (meth)acrylic acid can be used as the monomer component of the base polymer, and an ester formed with an alcohol having 12 or less carbon atoms can be used. In particular, a (fluorenyl) acrylic monomer having an alkyl group having 4 to 12 carbon atoms is preferred. The (meth)acrylic monomer may, for example, be methyl (meth)acrylate, ethyl (meth)acrylate, propyl (mercapto)acrylate, (mercapto)acrylic acid, n-butyl ester, Tert-butyl (meth)acrylate, isobutyl (meth)acrylate, amyl (meth)acrylate, hexyl (meth)acrylate, 2-ethyl hexyl (meth)acrylate, (A) Base n-octyl acrylate, isooctyl (meth)acrylate, n-decyl (meth)acrylate, isodecyl (decyl) acrylate, n-decyl (meth) acrylate, (methyl) propyl Isodecyl diester, (decyl) n-dodecyl acrylate. These bismuth acrylate monomers may be used singly or in combination of two or more. In the present invention, '(meth)acrylic acid-based polymer means an acrylic polymer and/or a mercaptoacrylic polymer, and (mercapto)acrylate means acrylate and/or methacrylate. . The (meth)acrylic polymer is preferably a (mercapto)acrylic polymer having 80 parts by weight of (meth)acrylic acid vinegar, based on 1 part by weight of the monomer component. In the (meth)acrylic acid polymer, the ratio of the alkyl (meth)acrylate is preferably 8 parts by weight or more (for example, about 80 to 99.8% by weight) based on 100 parts by weight of the monomer component. It is better to use 85 heavy U 々 v L system. If it is less than 80 parts by weight, stress relaxation is lacking, which is not preferable. In the present invention, a functional group-containing monomer having a functional group such as a trans group may be used. The kind of the functional group can be appropriately selected. 13 1375821 Specific examples of the above-mentioned functional group-containing monomer include, for example, (mercapto) acridine, itaconic acid, maleic acid, crotonic acid, maleic acid liver, 2-(indenyl) propylene oxide a fluorenyl-containing monomer such as ethyl succinic acid or 2-(methyl) propylene oxyethyl phthalic acid or an anhydride thereof; (meth) acrylamide, N,N-dimethyl(methyl) propyl Thin amine, N-hydroxydecyl (decyl) acrylamide, N-decyloxymethyl (decyl) propylene. · Amine, N-butoxymethyl (decyl) acrylamide, etc. Amidoxime-containing monomer; (methyl)-* 2-hydroxyethyl acrylate, 2-hydroxypropyl (meth) acrylate, 3-methyl propyl acrylate, (meth) propyl Dilute acid 2-butyl butyl ketone, (mercapto) propylene > acid 3-hydroxybutyl ester, (meth)acrylic acid 4-hydroxybutyl ester, polyethylene glycol mono (meth) acrylate, etc. An amine-containing monomer such as (fluorenyl) bis-decylamino acrylate, tert-butylaminoethyl (meth) acrylate; (meth) propyl propyl acrylate Monomer of propyl; (fluorenyl)propionitrile, (hexyl) acrylonitrile Morpholine, N- · 2 · ρ-vinyl pyrrolidone and the like. The functional group-containing monomer may be used singly or in combination, and the content of the monomer having a fluorenyl group is 100 parts by weight of the monomer component of the (fluorenyl) acrylic polymer, preferably 0 01. 2 parts by weight, and more preferably in parts by weight. If the content of the monomer having a functional group is less than 001 parts by weight, the crosslinking is insufficiently formed, and the durability is deteriorated, which is not preferable. On the other hand, if the monomer content of the yam-containing yam is more than 20 parts by weight, the adhesion to the liquid crystal element or the like may become too large or too good. The (fluorenyl) acrylic polymer used in the present invention has a weight average molecular weight of 10 to 5,000,000, preferably 20 to 4,000,000, more preferably 30 to 3,000,000. If the weight average molecular weight is less than 100,000, the cohesive force of the adhesive composition is 纥, and it is easy to produce a slag. On the other hand, if the weight average molecular weight exceeds 50,000, 1375821 1 », the fluidity of the polymer is lowered to make the affinity to the polarizing plate insufficient, and the peeling tendency is left between the adhesive composition layer of the optical member or the like. air. In the present invention, the weight average molecular weight is measured by GPC (gel permeatiation chromatography). The glass transition temperature (Tg) of the above (fluorenyl) acrylic polymer is 'below (usually _100 ° C or more), preferably -10 ° C or less. If the glass transition temperature is higher than 〇 ° C, the polymer does not easily flow, so that the affinity for the polarizing plate is insufficient, and the air is left between the polarizing plate and the adhesive composition layer of the surface protective film. The Tg of the (fluorenyl) acrylic polymer can be adjusted within the above range by appropriately changing the monomer component or composition ratio used. The glass transition temperature (Τ§) in the present invention means a one measured by a dynamic viscoelastic device. The polymerization method of the (meth)acrylic polymer used in the present invention is not particularly limited, and for example, a known method such as solution polymerization, emulsion polymerization, bulk polymerization, or suspension polymerization can be used. The obtained polymer may be either a random polymer or a block polymer. For example, when solution polymerization is used, a monomer polymerization agent may be added to a polymerization initiator such as azo-butyronitrile, and a polymerization solvent such as ethyl acetate may be used as a polymerization solvent. Nitrogen gas flow was carried out at 5 〇 to 70. (: The reaction is carried out for 8 to 30 hours to obtain a predetermined (meth)acrylic polymer. In the present invention, the '(meth)acrylic polymer can be used as a polymerization initiator in the polymerization. During the polymerization, the peroxide may remain in the adhesive composition layer without being reacted, but the residual peroxide may be used to adjust the peeling force of the release liner. Alternatively, the unreacted k oxide may be used. The residual amount is quantified, and a peroxide is added to a predetermined amount of peroxide as needed. 8 15 1375821 The 'decane coupling agent is not particularly limited in the invention, and a conventional one can be suitably used. For example, '3·epoxypropoxy group Propyltrimethoxydecane, 3-glycidoxypropyltriethoxydecane' 3_glycidoxypropylmercaptodiethoxydecane, 2-(3,4-epoxycyclohexyl Ethyl tridecyloxydecane-containing epoxy-containing decane coupling agent; 3-aminopropyltrimethoxy decane, N 2•(aminoethyl)_3_aminopropylmethyldimethoxy decane , an amine-containing decane coupling agent such as 3_triethoxydecyl _n (1,3_: decylbutylene) propylamine, 3 (meth)acrylic acid-containing decane coupling agent such as propylene oxypropyltrimethoxy decane, 3-mercapto propylene oxypropyltriethoxy decane, etc.; 3 · isocyanate propyl triethoxy decane, etc. The decane coupling agent containing an isocyanate group, etc. In the present invention, the decane coupling agent is preferably used in an amount of 100 parts by weight based on 100 parts by weight of the (meth)acrylic polymer. When the amount of the compounding is increased, the adhesion to the liquid crystal element is increased, and the removability is deteriorated. If the amount is too small, the sealing property may be lowered. The adhesive composition of the present invention It is excellent in heat resistance by appropriately mixing the (fluorenyl) acrylic polymer. The crosslinking agent used in the present invention is, for example, an 'isocyanate compound, an epoxy compound, a melamine resin, or a nitrogen heterocycle.

The gel component after crosslinking is in an amount of from 45 to 95% by weight, more preferably from 5 to 85% by weight. If the gel fraction is less than 45 deg/hr, a problem such as bubbles may occur in the heating test, and the cohesive force of the adhesive composition becomes small, causing the occurrence of slag. On the other hand, if the gel fraction is more than 95% by weight, the cohesive force of the adhesive composition becomes large, and the subsequent property is deteriorated. In the present invention, the 'gel fraction' indicates the degree of crosslinking, which is the ratio of the portion to be crosslinked by the adhesive. The gel fraction measurement method described above is as follows. The adhesive layer immediately after the cross-linking treatment was weighed and found to have a weight fraction (Wi)g. Next, it was coated on a microporous tetrafluoroethylene film (coated film weight Wdg), and ethyl acetate was about 25 at 50 mi. (: After soaking for 2 days, the soluble component was extracted and removed. Then, the pressure-sensitive adhesive layer was taken out from ethyl acetate at 11 Torr. The mash was dried for 1 hour, and the dried weight Ws (g) was measured. The gel fraction (% by weight) of the adhesive layer was determined according to the following formula, and after the coating, after storage for 1 week at room temperature, the gel fraction was measured. Gel fraction (% by weight) = (\^3-\¥2/\^)\100 The adhesive composition of the present invention contains the above (meth)acrylic polymer as a base polymer.

The water-based adhesive agent may, for example, beocyanate-based adhesive: polyethylene (iv) adhesive, bright (iv) adhesive, ethylene-based latex, polyurethane, water-based polyester, and the like. The surface of the light element can be prevented or spread or anti-glare treatment depending on the purpose. The transparent protective film is not subjected to a hard coat layer or a reflection preventing treatment or adhesion. 23 1375821 Hard: Layer: To prevent the surface of the polarizing plate from being damaged, for example, it may be cured or smoothed by a suitable ultraviolet curing resin such as acryl (four). The hardened film is attached to the surface of the transparent protective film. Anti-reflection treatment The external light is reflected on the surface of the polarizing plate for the purpose of implementation. The method of forming an anti-reflection film or the like to achieve the H-attachment prevention treatment is performed for the purpose of preventing adhesion to an adjacent layer. 2, in order to prevent external light from being reflected on the surface of the polarizing plate and obstructing the polarizing plate, firstly for the purpose of visual observation, etc. (4), for example, a sand method or a "roughening method such as a processing method or a method of blending transparent particles" In the field method, a fine concavo-convex structure is formed on the surface of the transparent protective film. As the fine particles for forming the fine concavo-convex structure, it is possible to control, for example, the average particle diameter of the ruthenium oxide, the oxidation, the oxidation, the oxidation, and the oxidation. Tin, indium oxide, and oxidized m materials are transparent particles such as organic fine particles composed of fine particles, parent or uncrosslinked polymers. The amount of fine particles used to form the surface fine concavo-convex structure is usually used to form a surface. The transparency of the fine concavo-convex structure is preferably 100 parts by weight, preferably 2 to 5 parts by weight, and is preferably 5 to 25 parts by weight. The anti-glare layer may also function to diffuse polarized light and transmit light to increase the diffusion of the viewing angle. Layer (viewing angle expansion function). The anti-reflection layer, adhesion prevention layer, diffusion layer or anti-glare layer may be used as other optical layers in addition to the transparent protective layer. It is provided separately from the transparent protective layer. The optical member of the present invention is, for example, a reflective plate or a semi-transmissive plate, a phase difference plate (including a 1/2 or 1/4 wavelength plate), a viewing angle compensation film, a brightness enhancement film, or the like. The display device is used to form an optical layer to be used. These may be used alone as the optical member of the present invention, or may be laminated on the polarizing plate in actual use. In particular, 'better in the polarized light a reflective polarizing plate or a semi-transmissive polarizing plate formed by further laminating a reflecting plate or a semi-transmissive reflecting plate, an elliptically polarizing plate or a circular polarizing plate formed by further laminating a phase difference plate on the polarizing plate, and a polarizing plate a polarizing plate having a wide viewing angle compensation film for further accumulating the viewing angle compensation film or a polarizing plate further laminated on the polarizing plate. The reflective polarizing plate is provided with a reflective layer on the polarizing plate, and is formed to be from the visual side (display) The liquid crystal display device of the display type is reflected by the incident light of the side, and the light source such as the built-in backlight can be omitted, and the liquid crystal display device can be easily made thinner. The formation of the light plate may be performed by a suitable method such as a transparent protective layer or the like, and a reflective layer made of a metal or the like may be provided on one surface of the polarizing plate, etc. Specific examples of the reflective polarizing plate include a transparent protective film (for example). Depending on the surface, a reflective metal or a vapor-deposited film such as aluminum may be provided on one surface to form a reflective layer, etc. Further, the transparent protective layer may be made to contain fine particles. The surface has a fine concavo-convex structure, and a reflective layer having a fine concavo-convex structure is provided thereon. The reflective layer of the fine concavo-convex structure can prevent directionality and flickering from being caused by irregular reflection and diffusion of human light. The case of light and dark markings is its advantage. It also contains the 'particles of the 5th layer of the moon, which can be diffused when the incident light and its reflected light penetrate.' It can further suppress the shading of light and dark, which is also its advantage. The formation of the reflective layer of the fine concavo-convex structure reflecting the fine concavo-convex structure of the transparent protective layer can be performed by, for example, vacuum steaming, ion implantation, 8 25 1375821 sputtering An appropriate method such as a vapor deposition method or a plating method, such as a method, is carried out by directly attaching a metal to the surface of the transparent layer. In addition to being directly attached to the transparent protective layer of the polarizing plate, a reflecting plate formed by providing a reflecting layer on a suitable film having the transparent film as a structure may be used. Further, since the reflective layer is usually made of a metal, the reflective surface is covered with a transparent protective layer or a polarizing plate, and the like; the soil; the reflectance due to vaporization is prevented from being lowered, and the initial reflectance is long. It is better to continue the point of view, or to avoid the need to set a separate protective layer. Further, the semi-transmissive polarizing plate can be obtained by providing a semi-transmissive reflective layer such as a semi-lens or the like which reflects the light and penetrates the light through the reflective layer. It is provided inside the liquid crystal element, and can be used to form a liquid crystal display device of the type that reflects the incident light from the visual side (display side) and displays the image when the liquid crystal display device or the like is used in a relatively bright environment. In a relatively dark environment, the image is displayed using a built-in light source such as a backlight embedded inside the semi-transmissive polarizing plate. That is, the semi-transmissive polarizing plate can be used to reduce the energy used by the moonlight-specific light source in a bright environment, and a liquid crystal display device of a type having a built-in light source can be used in a relatively dark environment. Next, an elliptical polarizing plate or a circular polarizing plate formed by further laminating a phase difference plate on a polarizing plate will be described. In the case where the linearly polarized light is converted into elliptically polarized or circularly polarized light, or the elliptically polarized or circularly polarized light is converted into linearly polarized light, or the linearly polarized light direction is changed, a phase difference plate or the like is required, in particular, as a linear polarized light is converted into a circle. A polarizing plate or a phase difference plate that converts circularly polarized light into linearly polarized light 26 8 1375821 can be a so-called quarter-wave plate (also referred to as a λ/4 plate). The ι/2 wavelength plate (also known as the "2 plate) is usually used to change the direction of polarization of linearly polarized light. The elliptically polarizing plate can compensate (prevent) the color (blue or yellow) generated by the birefringence of the liquid crystal layer of the super twisted nematic (STN) type liquid crystal display device, and can be effectively used for black and white display without coloring. Occasionally. Further, it is preferable to control the three-dimensional refractive index to compensate (prevent) the coloring which occurs when the screen of the liquid crystal display device is viewed from the oblique direction. The circularly polarizing plate' can be effectively used, for example, in the case of image hue adjustment of a reflective liquid crystal display device in which the image is a color display, and also has a function of preventing reflection. The retardation plate ′ is, for example, a birefringent film obtained by uniaxially or biaxially stretching a polymer material, an alignment film of a liquid crystal polymer, and an alignment layer supporting a liquid crystal polymer. The thickness of the phase difference plate is not particularly limited 'generally about 20 to 150 private m.

As such a viewing angle compensation, the difference plate is composed of, for example, a retardation film, an alignment film such as a liquid crystal polymer, or an alignment layer which supports a liquid crystal polymer or the like on a transparent substrate. A general phase difference plate is a polymer film which is uniaxially stretched and refracted in the direction of the surface thereof, and is used as a phase plate as a viewing angle compensation film for biaxial stretching in the plane direction. a polymer film having birefringence, or a polymer film having a refractive index in a thickness direction and a birefringent polymer film or a tilt alignment film, which is subjected to uniaxial stretching in the plane direction and also in the thickness direction. Stretching the film in two directions. As the oblique alignment film, for example, a heat shrinkable film is applied to the polymer film, and the polymer is subjected to a stretching treatment and/or shrinkage treatment under the action of heating to generate a shrinking force, or the liquid crystal is compounded. To the aligners and so on. The raw material polymer of the phase difference plate may be the same as the polymer described in the phase difference plate of the other surface, and may be colored, etc., which are suitable for preventing changes in the viewing angle based on the phase difference caused by the liquid aa element, or Expand the purpose of visually good perspectives, etc. Moreover, in order to achieve a wide range of good visual field of view considerations, it is preferred to support the optically anisotropic layer with triethylenesulfonyl cellulose (the tilt of the alignment layer of the liquid crystal polymer, especially the liquid crystal polymer) An optically compensated phase difference plate formed by the alignment layer. A polarizing plate which is formed by a polarizing plate and a brightness enhancement film is usually used inside the liquid crystal element. The brightness enhancement film exhibits the following characteristics: When the natural light is incident on the backlight of the liquid crystal display device or the reflection from (4), the linear polarization of the predetermined polarization axis or the circular polarization of the predetermined direction can be reflected to make the other Therefore, the polarizing plate laminated with the brightness enhancement film and the polarizing plate can cause light from a light source such as a backlight to be incident to obtain a penetrating light of a predetermined polarization state, and prevent light penetration other than the predetermined polarization state. It is reflected that the light reflected by the brightness enhancement film surface is reversely incident on the brightness enhancement film through a reflection layer or the like provided on the rear side thereof, so that part or all of the light is in a predetermined polarization state. In order to increase the amount of light transmitted through the brightness enhancement film and to supply the polarized light that is hard to be absorbed by the polarizing film, the amount of light that can be used for liquid crystal image display or the like is increased to increase the brightness. In other words, when the brightness enhancement film is not used and light is incident through the polarizing film inside the liquid crystal element such as a backlight, most of the light whose polarization direction does not coincide with the polarization axis of the polarizing film is absorbed by the polarizing film. Will pass through the polarizing film. That is, although the characteristics of the polarizing film to be used differ depending on the characteristics of the polarizing film to be used, substantially 50% of the light is absorbed by the polarizing film, and this portion causes the amount of light available to the liquid crystal display device to be reduced, resulting in darkening of the image. The brightness enhancement film prevents the light in the polarization direction absorbed by the polarizing film from being incident on the polarizing film, and is reflected by the lifting film, and is then folded back through the reflective layer provided on the rear side thereof and then incident on the brightness increasing film, thus repeating In the case where the light that is reflected and folded back between the two is supplied to the polarizing film by the polarized light that can pass through the polarizing direction of the polarizing plate, the display of the image of the liquid crystal display device can be effectively used. Make the image brighter. A diffusion plate may be provided between the brightness enhancement film and the reflective layer or the like. The diffusing plate provided by the light-receiving state reflected by the lift-free film toward the reflective layer or the like diffuses the passing light uniformly and eliminates the polarized light. The state of 13 1375821 becomes a non-polarized state. That is, return to the original natural light bear. The light in the non-polarized state (that is, the natural light state) travels toward the reflective layer or the like, is reflected by the reflective layer, and is incident on the brightness enhancement film through the diffusion plate, and is thus repeated. By providing a diffusing plate for returning to the original natural light state, the brightness of the display screen can be maintained, and the unevenness of the display screen can be reduced, and a uniform bright face can be provided. It is generally believed that by providing a diffusing plate for returning to the original natural light state, the initial incident light can provide a uniform bright display screen with the repetition of the appropriate reflection and the function of the diffusing plate. . As the brightness enhancement film, for example, a multilayer film of a dielectric or a multilayer laminate of a film having a different refractive index anisotropy can be suitably used, and other light can be reflected by linear polarization of a predetermined polarization axis. The characteristic is that if the alignment film supporting the cholesteric liquid crystal polymer or the alignment liquid crystal layer is supported on the film substrate, it is shown that either the left-handed or the right-handed circle can be polarized and reflected, and other light can be transmitted. Characteristics, etc. • Therefore, the above-described brightness enhancement film of a type that allows a linear polarization of a predetermined polarization axis to penetrate, by causing the transmitted light to be aligned with the polarization axis and incident on the polarizing plate, can suppress the loss of absorption by the polarizing plate, and can be efficiently worn. through. On the other hand, a brightness enhancement film of a type that allows a circularly polarized light to penetrate like a cholesteric liquid crystal layer can also cause light to be incident on the polarizing film locally, but suppresses the absorption loss. It is preferable that the phase difference plate is linearly polarized and then incident on the polarizing plate. Further, by using a quarter-wave plate, circularly polarized light can be converted into linearly polarized light. The 31 1375821 phase difference plate ' having a quarter-wave plate function in a wide wavelength range such as the visible light region can be formed by, for example, a phase difference layer that functions as a 1/4 wavelength plate for monochromatic light having a wavelength of 550 nm, and displays other A phase difference layer of a phase difference characteristic (for example, a phase difference layer functioning as a 1/2 wavelength plate) is superposed. Therefore, the retardation plate disposed between the polarizing plate and the brightness enhancement film may be composed of one or at least two or more retardation layers. Further, the cholesteric liquid crystal layer can be obtained by reflecting a circularly polarized light in a wide wavelength range such as a visible light region by combining the reflection wavelengths and the overlapping structure of two or at least three layers. The wide wavelength range of Lu penetrates the circular polarization. Further, the polarizing plate may be formed by laminating a polarizing plate and two or more optical layers as in the above-described polarizing-separating polarizing plate. Therefore, a reflective elliptically polarizing plate or a semi-transmissive elliptically polarizing plate formed by combining the above-described reflective polarizing plate or semi-transmissive polarizing plate and retardation plate may be used. The optical member formed by laminating the optical layer on the polarizing plate can be formed by laminating one by one in the manufacturing process of a liquid crystal display device or the like, and the optical member can be laminated in advance to achieve quality stability and assembly workability. The aspect is superior, so that the process of the liquid crystal display device and the like can be improved, which is an advantage. For the implementation of the laminate, an appropriate bonding means such as an adhesive layer can be used. When the polarizing plate is bonded to another optical layer, the optical axis of the polarizing plate can be appropriately arranged at an appropriate angle depending on the phase difference characteristics of the desired object. The respective layers of the adhesive optical member or the adhesive layer of the present invention may be, for example, a salicylate-based compound, a benzophenone-based compound benzotriazole-based compound, a cyanoacrylate-based compound, a nickel-salted salt-based compound, or the like. The ultraviolet absorber is treated to have ultraviolet absorbing ability. ' 5 32 1375821 The adhesive optical member of the present invention can be applied to the formation of various image display devices such as liquid crystal display devices. The formation of the liquid crystal display device can be carried out by a conventional method. In other words, the liquid crystal display device is generally formed by appropriately assembling a constituent member such as a liquid crystal element, an adhesive optical member, and an optional illumination system, and is added to a driving circuit or the like. The present invention does not require the use of the optical or structural member of the present invention. It is specifically limited, and a conventional constitution can be used. The liquid crystal element C can be used in any form such as a TN type, an STN type, or a π type. A liquid crystal display device in which an adhesive optical member ® is disposed on one side or both sides of a liquid crystal element, or a liquid crystal display device using a backlight or a reflector in an illumination system. In this case, the optical member of the present invention may be provided on one side or both sides of the liquid crystal element. If optical members are provided on both sides, they may be the same optical member or different. When forming a liquid crystal display device, one or two or more appropriate members may be disposed at appropriate positions, for example, a diffusion plate, an anti-glare layer, an anti-reflection film, a protective plate, a prism column, a lens array, a light diffusion plate, and a backlight. Wait. g Next, there is an electroluminescent device (organic EL display device). In general, an organic EL display device sequentially forms a transparent electrode, an organic light-emitting layer, and a metal electrode on a transparent substrate to form an illuminant (organic electroluminescence).

That is, a voltage is applied to the transparent electrode and the gold > 1 electrode to implant the hole in the organic light-emitting layer and the recombination of the electron hole and the electron. The energy excites the fluorescent substance, and the excited fluorescent substance emits light when it returns to the ground state. This mechanism is combined with the general diode in the middle, and it can be inferred that the current and the luminous intensity are applied. The voltage display is accompanied by the rectification of the strong non-linearity. In the organic EL device, the electrode for deriving the light from the organic light-emitting layer to the side must be a transparent electrode, which is usually transparently conductive by indium tin oxide (ITO) or the like. The transparent electrode formed by the body is used as an anode. On the other hand, in order to make electron implantation easy to improve luminous efficiency, it is important that the cathode uses a substance having a small work function, and generally MgAg, Al-Li, or the like can be used. In the organic EL device having the above configuration, the organic light-emitting layer is usually formed by a film having a thickness as thin as lOnm. Therefore, the organic light-emitting layer and the transparent light are formed. Similarly, the light can be almost completely penetrated. Therefore, the light that is incident on the surface of the transparent substrate from the surface of the transparent substrate and that is reflected by the organic light-emitting layer and is reflected on the metal electrode is emitted to the surface side of the transparent substrate again. When viewed from the outside, the display surface of the organic EL device is mirror-finished. The organic EL emitter (the surface of the organic light-emitting layer that emits light by applying a transparent electrode and the metal electrode on the back side of the organic light-emitting layer) are organic. In the EL display device, for example, on the surface side of the transparent electrode, the J·@俗a JL polarizing plate is provided, and a phase difference plate is disposed between the transparent electrode and the polarizing plate. 0 34 5 1375821 The phase difference plate and the polarizing plate have The externally incident light that is reflected by the metal electrode is polarized. Therefore, the polarizing effect can be used to confirm the mirror surface of the metal electrode from the outside. This is the effect. In particular, it is composed of a quarter-wave plate. By adjusting the angle of the polarizing plate and the polarization direction of the retardation film to π/4, the mirror surface of the metal electrode can be completely covered. 》 • For external light incident on the organic EL display device, only the linearly polarized component of the polarizing plate can penetrate the linearly polarized light by the retardation film—which can be elliptically polarized, but when the retardation film is 1/4 wavelength When the angle between the plate and the polarizing plate and the retardation film is 7 Γ /4, it becomes circularly polarized. This circular polarized light usually penetrates the transparent substrate, the transparent electrode, and the organic film, and is reflected at the metal electrode. The penetrating film of the organic film, the transparent electrode, and the transparent earth plate is again linearly polarized. This linear polarized light cannot penetrate the polarizing plate because it is orthogonal to the polarizing direction of the polarizing plate. Thus, the mirror surface of the metal electrode can be completely completed.

The adhesive layer for an optical member which easily adjusts the peeling force of the fluorenone release liner, and the optical member for attaching the adhesive (refer to FIG. 1). On the other hand, in the process of decomposing the peroxide on the release liner (Comparative Examples 1, 3 to 4, 6, 8, 12), although the durability is good, the release liner of either of the release liners The force is relatively small. 1N/5〇mm is small, and then the force is not sufficient. On the other hand, in the case where the peroxide decomposition amount is higher than 20/zm 〇 1 (Comparative Examples 2, 5, 7, and 9), although the durability is excellent, the peeling force of any of the peeling profiles is 0.4 N/50 mm. It is too large to make the peeling force too large. On the other hand, in the case where the Shishiyuan coupling agent was not contained (Comparative Example 1~u), although it had an appropriate peeling force, the durability was not good. Therefore, it has been confirmed that the pressure-sensitive adhesive layer of the present invention can produce an adhesive layer for an optical member which is excellent in durability and has an appropriate peeling force, and an optical member for attaching the adhesive.
