Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing a composite polarizing plate. [Prior Art] A liquid crystal display device utilizes characteristics such as low power consumption, low voltage operation, light weight, and thinness. Used in a variety of display devices. This liquid crystal display device is composed of a plurality of optical members such as a liquid crystal cell, a polarizing plate, a phase difference film, a light collecting sheet, a diffusion film, a light guiding plate, and a light reflecting sheet. Here, by reducing the number of films or sheets constituting the optical members, or reducing the film thickness, it is possible to achieve an improvement in the production rate or brightness of the liquid crystal display device and a light weight. Thinning, etc., these researches are doing a great job of reducing the number of sheets constituting a film or a sheet to reduce the thickness of the L 曰 display device. It is known that the protective film on one side of the polarizing side also serves as a phase difference. The method of film. For example, in Japan, the special Kailuan ^ Na 2 ❹ ❹ (Special υ υ ' ' 将 赖 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ A coal-based resin is used to form at least one of the protective films. In addition, Japanese Laid-Open Patent Publication No. Hei 9-325216 (Patent Document 2) discloses a transparent and transparent polarizing film formed of a birefringent film (retardation film). The protective layer. On the other hand, one of the functions required for the retardation film is that the phase difference caused by the liquid helium is phased in the front direction or the oblique direction. The angle dependence of the phase difference is the important optical characteristic of the 321537 3 201022740. Here, there are several proposals for the phase turbulent film whose phase difference is almost constant regardless of the angle. For example, 曰本特开平2-16〇2 In the publication No. 4 (Maori Document 3), it is disclosed that a film having a normal birefringence (intrinsic birefringence) and a molecule aligned in the normal direction of the thin face is extended to form a phase of normal incidence. Difference and "from the law The phase difference incident in the direction of the inclination 40 is substantially the same as the phase shading film. When the refractive index in the in-plane slow direction and the in-plane fast axis direction in the thickness direction are respectively set to ^, and (1), The relationship between ηχ>ηζ7 ° Hy is shown. The method for producing a retardation film which satisfies the relationship of nx > nz > ny2 is disclosed in Japanese Laid-Open Patent Publication No. Hei 5-157911 (Patent Document 4). a method of forming an integrated body on one side or both sides of a resin film, and then heating and stretching the laminated body. This method is to shrink the resin film while being perpendicular to the axis of its extension. The method of aligning in the thickness direction (Z direction) causes the refractive index distribution of the resin thin Q film to vary greatly before and after the stretching. Therefore, the tree ruthenium film used in the manufacturing method is easy to generate phase by low stretching ratio. In the past, it has been used such as a polycarbonate film, a P0lyaryiate resin film, and a p〇lysulf〇ne resin film. In the Japanese Patent Laid-Open Publication No. Hei 7--23-23 (Patent Document 5), it is not limited by the heat shrinkability of at least one side of the uniaxially stretched thermoplastic resin film. The crucible is bonded in such a manner that its heat shrinkage direction is perpendicular to the direction of the extension axis of the thermoplastic resin 4321537 201022740, and heat shrinkage is performed to produce a retardation film. The phase difference film thus obtained is also in the thickness direction thereof. Since the aligning of the uniaxially stretched thermoplastic resin film by the heat shrinkage of the heat-shrinkable film is carried out in the thickness direction, the aromatic resin film which easily exhibits a phase difference is mainly used. However, since the aromatic resin film has a large absolute value of the photoelastic coefficient, the phase difference is likely to change with respect to stress. Therefore, when the bonding parameter is exposed to a high temperature in a state in which the bonding film is disposed between the liquid crystal cell and the polarizing film, the phase difference may exceed the design value due to the contraction stress of the polarizing film, which is due to the backlight of the liquid crystal display device. The uneven stress caused by heat causes unevenness in phase difference, which causes problems in deterioration of display characteristics. In the aliphatic resin film such as a cyclic olefin resin film, the absolute value of the photoelastic coefficient is small, and in recent years, the direction suitable for the retardation film is increasing. However, the aliphatic resin film generally does not easily exhibit a phase difference, and it is of course difficult to express a phase difference at a low stretching ratio such as an aromatic resin film, and it is difficult to obtain a desired phase difference even if the stretching ratio is increased. . In particular, it is difficult to obtain the desired phase difference in the direction of the extension axis and the thickness 2, and the method described in Patent Document 4 and Patent Document 5 is used to use an aliphatic resin film. There are limits to it. In the Japanese Patent Publication No. 2006-72309 (Patent Document 6), it is disclosed that a shrinkable film having a large shrinkage ratio in the width direction is bonded to one side or both sides of a film of a cyclic olefin. The method in which the in-plane phase difference is 1 〇〇 to 321537 5 201022740 350 nm and the coefficient (N2 coefficient) shown by (nrnz)/(nx-ny) is 0.9. Here, ηχ and n have the above-described method, and the cyclic olefin-based resin film which rides on the two-dimensional difference can be aligned at the same time in the direction of the extension axis: the thickness of the fish, and the production satisfies nx>nz> The phase difference of the W relationship is thin. 〇❹ However, the retardation film which is composed of a film containing the above-mentioned cyclic olefin-based resin film and which satisfies the relationship of nx > nz > ny is: the width of the film which can be produced due to the shrinking step in the manufacturing process thereof There is a case where the width of the polarizing film is smaller than that of the polarizing film, and the conventional polarizing plate method has a problem that the productivity is remarkably lowered. In other words, at this time, if a phase difference film having a smaller degree than the polarizing plate is bonded, the polarizing plate portion m having a phase difference is generated. (10) The polarizing plate is cut and bonded to the liquid crystal cell. The predetermined shape is usually cut at a right angle or an oblique angle with respect to the long-term production direction, and then cut into the predetermined shape again, and the portion of the polarizing plate that is not attached with the retardation film is scrapped. Further, since the portion of the polarizing plate to which the phase difference _ is not attached is also added to the cutting length, the productivity is remarkably lowered. Further, a retardation film composed of a cyclic olefin-based resin film, when used as a protective film for a polarizing film, may be inferior to a foreign film. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a composite polarizing plate with good productivity.

When the olefin-based resin film of the formula (1) and (2) is satisfied with respect to light having a wavelength of 590 nm, it is preferable that: 10000 nm (nx-ny) xd^ 300 nm (1) 0. 1 ^ (nx-nz) / (nx-ny) ^0.7 (2) In the second production method of the present invention, the thin hydrocarbon resin film is preferably composed of a resin mainly containing a constituent unit derived from an alicyclic olefin. Further, in the second manufacturing method of the present invention, the retardation film is preferably such that its width is 10% or more smaller than the width of the polarizing plate having the transparent protective film on one side thereof. In the second production method of the present invention, it is preferred that the polarizing film and the transparent protective film are adhered by a water-soluble adhesive containing a polyvinyl alcohol resin and an epoxy resin. Further, in the second manufacturing method of the present invention, it is preferred to use an adhesive composed of a solventless resin composition containing 9 321 537 201022740 having an irradiated active energy ray or heat-hardened epoxy resin, and The polarizing film is followed by a transparent protective film. In this case, the epoxy resin is preferably a compound containing one or more epoxy groups bonded to an alicyclic ring in the molecule. In the second manufacturing method of the present invention, the thickness of the transparent protective film is preferably 20 to 300 /z m. Further, in the second manufacturing method of the present invention, the thickness of the adhesive layer is preferably from 1 to 40 // m. According to the manufacturing method of the composite polarizing plate of the present invention, before the film is bonded to the retardation film, the polarizing plate with the transparent protective film on one side is matched with the retardation film to be cut along the length direction, and is divided into a retardation film. A polarizing plate with a transparent protective film on one side and a polarizing plate with a transparent protective film on one side not attached to the retardation film are bonded, thereby reducing the productivity. Further, since the portion of the polarizing plate having the transparent protective film attached to the single side which is not bonded to the retardation film can be utilized for other products, the overall productivity can be remarkably improved. In addition, on the side of the polarizing film of the polarizing plate with the transparent protective film on one side of the cut, the adhesive film can be prevented from adhering or the polarizing film by adhering the adhesive film to the polarizing film in advance. Damage to the polarizing film at the time of cutting. [Embodiment] (Polarizing film) The polarizing film used in the method for producing a composite polarizing plate of the present invention means that 10 321 537 201022740 has a function of selectively penetrating linearly polarized light in a certain direction from natural light. For example, an iodine-based polarizing film in which a moth is adsorbed and aligned in a polyethylene-based film, a dye-based polarizing film in which a dichroic dye is adsorbed and aligned in a polyvinyl alcohol-based film, and a coating-dissolving film A dichroic dye which is in a lyotropic liquid crystal state and which is aligned, a coated coating type polarizing film or the like. These iodine-based polarizing films, dye-based polarizing films, and coating-type polarizing films are those having a linear eccentricity that selectively penetrates in one direction from natural light and absorbs the other direction. It is an absorption type polarizing film. The polarizing film used in the production method of the present invention may be not only the above-mentioned absorbing polarizing film, but also having a linearly polarized light that is polarized in one direction from natural light and a linearly polarized light in the other direction being reflected or scattered. The function of the function is called a reflective polarizing film or a scattering type polarizing film. Further, the polarizing film specifically exemplified herein is not necessarily limited to this, and may be any one having a function of selectively penetrating linearly polarized light in a certain direction from natural light. Among these polarizing films, an absorbing iridium type polarizing film excellent in visibility is preferable, and an iodine-based polarizing film excellent in polarization degree and transmittance is more preferable as the polarizing film. The polyvinyl alcohol-based resin used for the polyvinyl alcohol-based film is obtained by saponifying a polyvinyl acetate-based resin. The polyvinyl acetate-based resin may, for example, be a polyvinyl acetate such as a homopolymer of vinyl acetate, or a copolymer of vinyl acetate and another monomer copolymerizable therewith. Other monomers which can be copolymerized with vinyl acetate include unsaturated carboxylic acids, unsaturated sulfonic acids, olefins, and vinyl ethers. 11 321537 201022740 n Polyvinyl alcohol resin specialization degree is usually 85 to 10 〇 m〇l%, with 98 to 100% by mole * technology. The vinyl alcohol-based resin can be modified, for example, by using a modified type of polyvinylformal, polyvinvl 丄nylacetal, and polyvinyl butyral.

From the standpoint of workability, it is preferred that the polymerization initiator be given to a latent person. The flexibility of the protective film after the reduction is reduced, or the intensity of the active sub-species such as ultraviolet rays, X-rays, and electron beams or Lewis acid, regardless of the cation from the viewpoint of starting the epoxy group Hereinafter, a photocationic polymerization initiator which generates a cationic species or a Lewis human acid by irradiation with an active energy ray will be described. If photocationic polymerization: the initiator is used, it can be hardened at room temperature, and the necessity of considering the resistance of the polarizing film or the internal stress caused by thermal expansion can be reduced, and the transparent protective polarizing can be favorably followed. In addition, due to the photocationic version. The initiator is catalyzed by light, so that the mixed epoxidation is excellent in both qualitative and workability. Examples of the compound which produces a ruthenium species or a Lewis acid by irradiation with an active money line include, for example, an aromatic diazonium = (^laz〇niumsalt), an aromatic sulfonium salt (i〇d〇niumsait), and an aromatic salt. (SulfGnium salt) and other rust salts - New Zealand (1) and iron - Aiiene complexes.

These photocationic polymerization initiators can be easily obtained from commercially available products, and, for example, may be listed as follows: Kayarad PC 1-220 (manufactured by Nippon Kayaku Co., Ltd.), Kayarad PCI-620 (Japanese Chemicals ( Co., Ltd.), UVI-6990 (manufactured by Union Carbide), ADEKA Optomer SP-150 (made by ADEKA), ADEKA Optomer SP-170 (made by ADEKA), CI-5102 (Japan Soda) System), CIT-1370 (Japan Soda (share) system), CIT-1682 (Sakamoto Soda (share) system), CIP-1866S (Japan Soda (share) system), CIP-2048S (Sakamoto Soda (share) System), CIP-2064S (Japan Soda Co., Ltd.), DPI-l〇l ❹ (Midori Chemical Co., Ltd.), DPI-102 (Midori Chemical Co., Ltd.), DPI-103 (Midori Chemical Co., Ltd.) )), DPI-l〇5 (Midori Chemical Co., Ltd.), MPI-l〇3 (Midori Chemical Co., Ltd.), MPI-105 (Midori Chemical Co., Ltd.), BBI-101 (Midori Chemical) (share) system, BBI-102 (Midori Chemical Co., Ltd.), BBI-103 (Midori Chemical Co., Ltd.), BBI-105 (Midori Chemical Co., Ltd.), TPS-101 (Midori Chemical (share) )system ), TPS-102 (Midori Chemical Co., Ltd.), TPS~l〇3 (Midori Chemical Co., Ltd.), TPS-105 (Midori Chemical Co., Ltd.), MDS-103 (Midori Chemical Co., Ltd.) , MDS-105 (Midori Chemical Co., Ltd.), DTS-102 (Midori Chemical Co., Ltd.), DTS-103 (Midori Chemical Co., Ltd.), pi-2074 (manufactured by Rhodia Co., Ltd.), and the like. The compounding amount of the photocationic polymerization initiator is usually from 0.5 to 20 parts by weight, preferably from 1 part by weight to 15 parts by weight, based on 100 parts by weight of the epoxy compound. A photosensitizer 28 321537 201022740 (photosensitizer) may be used in combination in the curable composition. By using a photosensitizer, the reactivity can be increased and the mechanical strength and strength of the cured product can be increased. The photosensitizer may, for example, be a carbonyl compound, an organic sulfur compound, a persulfide compound, a redox system compound, an azo or diazo compound, a halide, or a photoreductive dye. When the photosensitizer is formulated, the amount of the photosensitizer is usually from about 0.1 to about 20 parts by weight based on 1 part by weight of the photocationically polymerizable epoxy resin composition. Next, the description will be made on the thermal cationic polymerization initiator.

For example, the following product names: ADEKA 〇ρΐ〇η cp77 (made by ADEKA Co., Ltd.) and ADEKA Opton CP66 (ADEKA Opton CP66) can be respectively listed. ), CI-2639 ❹ (Japan Soda (share) system), Cl-2624 (Japan Soda (share) system), SanAid SI-60LC Sanxin Chemical Industry Co., Ltd.), SanAid SI_8〇L (Sanshin Chemical Industry) (share) system, SanAidSI-l〇〇L (Sanshin Chemical Industry Co., Ltd.) and so on. Photocationic polymerization and thermal cationic polymerization, which are described in detail, are also useful techniques. The epoxy-based (4) may further contain a compound which promotes cationic polymerization such as an oxygen heterocyclic ring (F) or a polyhydric alcohol. Applying an adhesive composed of such a hardenable composition to the adhesive surface of the transparent protective film or the polarizing film, and bonding the two, and then hardening the adhesive by using 321537 29 201022740, the polarizing thin can be obtained. A laminate of tantalum and a transparent protective film. The method of applying the adhesive to the transparent protective film or the polarizing film is not particularly limited, and for example, a doctor blade coating method, a wire-bar coating method, or a die coating method can be employed. Various coating methods such as a comma coater and a gravure coating method. The thickness of the layer is usually 1/im or more and 5 〇 or less, preferably 20/zm or less, more preferably 10/zm or less. When the curing of the adhesive is performed by irradiating the active energy ray, the light source used is not particularly limited. For example, a low-pressure mercury lamp, a medium-pressure mercury lamp, a high-pressure mercury lamp, or a high-pressure lamp having a calender distribution at a wavelength of 40 〇 nm or less may be cited. Mercury lamps, chemical lamps, black light lamps, micro-slope excited mercury lamps, and metal halide lamps. The irradiation intensity of the wavelength region in which the activation of the photocationic polymerization initiator is effective is 0.1, and the irradiation intensity of the wavelength region effective for activation of the photocationic polymerization initiator is 0.1. It is better to 1〇〇mW/cm2. When the light irradiation intensity for the adhesive grade is less than 0.1 mW/cm2, the reaction time becomes too long 'when it exceeds 100 mW/cm2' due to the heat emitted by the lamp and the composition of the curable xylo-resin When the substance is heated during polymerization, yellowing of the composition of the curable epoxy resin or deterioration of the polarizing film may occur. In the same manner, the light irradiation time of the composition of the adhesive is determined according to the curability of the composition, and is not particularly limited. For example, the integrated light amount expressed by the product of the irradiation intensity and the irradiation time is 10 to 5000 mJ. /cm2 is better. If the total amount of light of the curable epoxy resin composition is less than 1 μm/cm 2 ', the production of the active species derived from the photocationic polymerization initiator may be insufficient 'sometimes, the hardening of the next 30 321537 201022740 agent may be caused. Not enough. In addition, if the integrated light amount exceeds 5 〇〇〇 mJ/cm2, the irradiation time becomes very long, which is disadvantageous in terms of productivity improvement. When the adhesive is cured by heat, the heating can be carried out by a method known in the art. The conditions are not particularly limited, and the thermal cationic polymerization in the curable epoxy resin composition is usually carried out. The starter is heated to a temperature above which the cationic species or Lewis acid is generated, for example, from about 5 Torr to about 200 °C. _ Whether it is hardened under any condition of irradiation with active energy rays or heating, the polarizing degree, transmittance, color, transparency of transparent protective film, etc. of polarizing plate with transparent protective film on one side are not reduced. Hardening is preferred in the range of functions. The thickness of the hardened layer obtained by hardening the adhesive composition is usually 50#m or less, preferably 2〇#m or less, more preferably 1〇//m.

Among them, a polyethylene terephthalate film, a polypropylene film, or a polyethylene film is suitable from the viewpoint of appropriately adjusting the adhesion and easily obtaining a commercially available product. / The peelable film has self-adhesiveness and can be directly bonded to the side opposite to the side of the polarizing film-film to which the transparent protective film is bonded. 31 321537 201022740 So that the transparent protective film is bonded to one side of the polarizing film by the adhesive, and the adhesive film is adhered to the opposite side of the polarizing film. The polarizing plate is temporarily taken up to the core of the gasification tube (such as (7) re) by taking up the coil. Further, the step of bonding the transparent protective film to the polarizing film and the step of laminating the peeling film to the polarizing film may be carried out first or simultaneously.

For example, dicyclopentadiene or dimethanooctahydronaphthalene is exemplified. These are mainly trees 32 321537 201022740 which are composed of constituent units derived from norbornene-based monomers, and are generally referred to as norbornene-based resins. The norbornene-based resin containing a constituent unit derived from a norbornene-based monomer may have a norbornane ring in its constituent unit or may have no norbornane ring. The norbornene-based monomer which forms the norbornene-based resin having no norbornane ring in the constituent unit is, for example, a 5-membered ring by ring opening, and representative examples thereof include norbornene and dicyclopentadiene. , 1- or 4-methylnorbornene, and 4-phenylnorbornene. When the norbornene-based resin is a copolymer, the arrangement state of the molecules is not particularly limited, and may be a random copolymer, and the block copolymer may be a block copolymer or a graft copolymer.

The other monomer in the copolymer may, for example, be an α-olefin, a cycloaliphatic milk or a non-conjugated diene. Further, the cyclic olefin resin may be a copolymer of one or more of a norbornene-based monomer and another alicyclic olefin. Among them, the cyclic olefin resin is preferably a resin obtained by hydrogenating a ring-opening polymer or a ring-opening copolymer using a norbornene-based monomer. The norbornene-based resin is subjected to an elongation treatment to obtain a film-like material, and a shrinkable film having a predetermined shrinkage ratio is attached thereto and heat-shrinked, whereby a uniformity and a large phase difference value can be obtained.

In addition, the retardation film used in the production method of the present invention may be a film three composed of three mixed waxes of two or more kinds of olefin resins or a mixed resin of an olefin resin and another thermoplastic resin. film. For example, a mixed resin containing two or more kinds of olefin-based resins may, for example, be a mixture of the above-mentioned cyclic olefin-based resin and acyclic aliphatic olefin-based resin. When a mixed resin of an olefin resin and another thermoplastic resin is used, the other thermoplastic resin is appropriately selected depending on the purpose. For example, 'polygasification-based vinyl resin, cellulose resin, polystyrene resin, acrylonitrile/butadiene/styrene copolymer resin, acrylonitrile/bake-bake copolymer resin, (methyl) Acrylic resin, polyvinyl acetate resin, polyvinylidene chloride resin, polyamine resin, polyacetal resin, polycarbonate resin, modified polyether ether resin, polyparaphenylene Butane bismuth vinegar resin, polyethylene terephthalate resin, polyphenylene sulfide resin, polysulfone resin, polyether oxime resin, polyether ketone resin, poly aromatic An ester resin, a liquid crystal resin, a polyamidene-based resin, a polyimide resin, and a polytetrafluoroethylene resin. These thermoplastic resins may be used alone or in combination of two or more. Further, the thermoplastic resin may be used after any suitable polymer modification. Examples of the modification of the polymer include, for example, copolymerization, crosslinking, molecular end modification, and stereoregularity. When a resin which meets the requirements of other thermoplastic resins is used, the content of the other thermoplastic resin is usually 5% by weight or less based on the total amount of the resin, and preferably 40% by weight or less. When the content of the other thermoplastic resin is within this range, a retardation film having a small absolute value of the photoelastic coefficient, excellent wavelength dispersion characteristics, and excellent durability, mechanical strength, and transparency can be obtained. These olefin-based resins can be formed into a film by a casting method by a solution or a melt-squeezing method or the like which is generally used. When the film is formed of a mixture of two or more kinds of resins, the film forming method is not particularly limited. For example, the following method may be employed. A uniform solution obtained by stirring and mixing the resin component with a solvent in a predetermined ratio is used. A method of forming a film by a washing method; a method of melt-mixing a resin component in a rich ratio, and a method of squeezing and extruding an old film. The film composed of the above-mentioned women's hydrocarbon tree will contain residual solvent, stabilizer, plasticizer, anti-aging agent and antistatic agent as needed within the scope of the purpose of the present invention. And pots and other ingredients such as UV absorbers. Further, in order to reduce the surface roughness, a leveling agent may be contained.

At the same time, the polarizing film surface and the retardation film are bonded together using an epoxy resin composition containing an epoxy resin which is cured by irradiation of an active energy ray or heating (step (C)). (Epoxy resin composition for retardation film bonding) An epoxy resin composition containing an epoxy resin which is cured by irradiation with an active energy ray or heating, which is used when the polarizing film and the retardation film are bonded together, Solvent-free is preferred. The epoxy resin composition may be the same as those exemplified as the adhesive used when the polarizing film and the retardation film are bonded. The method of adhering the polarizing plate and the retardation film having the transparent protective film on one side to the retardation film is not particularly limited, and for example, a doctor blade coating method, a wire bar coating method, a die coating method, and a comma method may be employed. Various coating methods such as a coating method and a gravure coating method. Further, a method in which the above-mentioned adhesive composition is dropped between the polarizing film and the protective film, and then the polarizing film and the protective film are pressed by a roller or the like and uniformly extruded. Here, the material of the roller may be metal or rubber, and the rollers may be of the same material or different materials. The thickness of the subsequent layer is usually 50/zm or less, preferably 20/zm or less, more preferably 10/m or less. When the curing agent is cured by irradiation of an active energy ray, the light source to be used is not particularly limited, and examples thereof include a low-pressure mercury lamp, a medium-pressure mercury lamp, a high-pressure mercury lamp, an ultra-high pressure mercury lamp, and a chemistry having a light-emitting distribution at a wavelength of 400 nm or less. Lamp, black light, microwave-excited mercury lamp and metal halide 38 321537 201022740 Prime lamp, etc. The light intensity of the composition of the adhesive is based on the composition of the composition (there is no limitation, but for example, The irradiation intensity in the wavelength region effective for photocationic polymerization is effective from .. to 1 〇 mw/(10) is preferable. When the intensity of light irradiation for the subsequent product is less than 1 mW/ In the case of Cm, the reaction time becomes too long. When the temperature exceeds (10), the heat generated by the lamp 4 and the heat of the curable epoxy resin composition are heated, and a hardening epoxy resin sometimes occurs. The yellowing of the composition or the deterioration of the polarizing film (5). The light irradiation time of the adhesive composition is determined depending on the hardenability of the composition, and is not particularly limited. For example, the irradiation intensity and the irradiation are set. The amount of integrated light indicated by the product of time is preferably 10 to 5j) 00 mJ/em. When the total amount of light in the curable epoxy resin composition is less than 10 mJ/cm, the generation of the active species derived from the photocationic polymerization initiator may be insufficient. The curing of the adhesive may be insufficient. Further, if the integrated light amount exceeds 5000 mJ/cm2, the irradiation time becomes extremely long, which is disadvantageous in productivity improvement.

The composite polarizing plate thus formed is usually disposed such that the retardation film side faces the liquid crystal cell when it is bonded to the liquid crystal cell. [Second Manufacturing Method of Composite Polarizing Plate] The second manufacturing method of the composite polarizing plate of the present invention comprises the following steps (A), (B), (C), (D) and (E) ). • Step (A) A step of laminating a transparent protective film to one side of the polarizing film, and attaching an adhesive peelable film to the opposite side to form a polarizing plate having a transparent protective film on one side. • Step (B) A step of cutting the polarizing plate having the transparent protective film on one side with the width of the retardation film and cutting it along the length direction. • Step (C) A step of removing the release film from the surface of the polarizing film. • Step (D) The polarizing film surface of the polarizing plate with the transparent protective film on one side of the retardation film or the one step after the step (C) is displayed at 80 ° C. A step of laminating an adhesive layer that stores a modulus of elasticity. 40 321537 201022740 • Step (E) The step of adhering the retardation film to the surface of the polarizing film on which the peelable film has been removed, via the adhesive layer. The second manufacturing method of the composite polarizing plate of the present invention thus comprises three major embodiments (the first aspect, the second aspect, and the third aspect). First, each embodiment included in the second manufacturing method of the present invention will be described. &lt;First Aspect&gt; The first aspect of the second manufacturing method of the present invention sequentially includes the above steps (^), (B), (C), (D), and (E) And in the step (D), the adhesive layer is laminated on the surface of the polarizing film of the polarizing plate having the transparent protective film attached to the one surface after the step (C). In a first aspect of the second manufacturing method of the present invention, first, a transparent protective film is bonded to one side of the polarizing film, and a peeling film having adhesiveness is attached to the opposite side surface to produce a single side. A polarizing plate with a transparent protective film (step (A)). φ In the first aspect of the second manufacturing method of the present invention, secondly, the polarizing plate having the transparent protective film on one side as described above is blended with the width of the retardation film and cut along the length direction ( Slitting) (Step (B)). The width of the polarizing plate having the transparent protective film on one side is appropriately set according to the width of the retardation film, and for example, at least one of the polarizing plates having the transparent protective film on one side after the cutting is preferably used. The width of the fragment and the retardation film are the same width. The method of cutting the polarizing plate with a transparent protective film on one side is not particularly limited, and a method of feeding a polarizing plate having a transparent protective film of 41 321537 201022740 to a slit is generally employed. The machine (cutting machine in the length direction) is engaged with the cutting method, and then the method of rewinding the plurality of cut pieces. Further, a polarizing plate which is cut by the width of the retardation film may be used, and a method of bonding the film to the retardation film via an adhesive may be used in the field. In the first aspect of the second manufacturing method of the present invention, the release film is then removed from the surface of the polarizing film (step (c)). Furthermore, in the first aspect of the second manufacturing method of the present invention, after the step (c), the polarizing film surface of the polarizing plate having the transparent protective film on one side thereof (that is, the original adhesive peeling film) The surface of the adhesive layer which exhibits a storage elastic modulus of 0. IMPa or more at 80 ° C is laminated (step (D)).至以上的范围内。 The adhesion coefficient of the adhesive agent for forming the adhesive layer at 80 ° C is 0. IMPa or more, preferably from 0.15 to lOMPa. When the storage elastic modulus at 80 ° C is less than 0. IMPa, the dimensional change of the polarizing film due to repeated high temperature environment and low temperature environment cannot be followed, and defects such as bubbles and peeling may occur. 2至10MPa。 In addition, the adhesion coefficient of the adhesive is preferably 0. 2 to lOMPa. Further, since the storage elastic modulus generally tends to be lower as the temperature is higher, the storage elastic modulus of the material measured at 80 ° C is 0. IMPa or more, usually 23 ° C. The storage elastic modulus of the same material measured will show the above value. Here, the storage elastic modulus (dynamic elastic modulus) is a term used for the measurement of the viscoelasticity generally used, and the strain or strain which is subjected to the change (vibration) to the sample is measured, and the stress or strain thus generated is measured, and the sample 42 is measured. 321537 201022740 The method of mechanical properties (dynamic viscoelasticity measurement) is the value sought. Specifically, it refers to a stress (strain) generated by applying a strain (stress) of a sinusoidal waveform to a sample, and is divided into a phase component having a phase deviation of 90 degrees from a phase of strain (stress), and strain and strain. (stress) The coefficient of elasticity calculated from the stress (strain) component of the same phase. The storage elastic modulus can be measured by using a commercially available viscoelasticity measuring device, for example, a dynamic viscoelasticity measuring device (Dynamic Analyzer RDA II: manufactured by RE0METRIC Co., Ltd.) disclosed in the examples. The temperature control of the viscoelasticity measuring device uses a conventional temperature control device such as a circulating thermostat, an electric heating device, or a Peltier element, thereby setting the temperature at the time of measurement. The adhesive used in the conventional image display device or the optical film to be used thereof has a storage elastic modulus of at most about 0.1%, but the adhesive used in the production method of the present invention has a high storage elastic modulus as described above. By. By using such an adhesive having a high storage modulus of elasticity, that is, by using a hard adhesive, it is possible to compensate for insufficient cohesive force when placed in a high temperature environment or repeatedly placed in a high temperature environment and a low temperature environment. It is possible to suppress the dimensional change accompanying the shrinkage of the polarizing film which is generated at this time. Due to this effect, the composite polarizing plate of the present invention has good durability.
