Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical layered body for a liquid crystal display device, and more particularly to a glass or plastic sheet comprising a liquid crystal display device. An optical layered body in which a polarizing plate is laminated on a liquid crystal cell substrate via an adhesive layer. Further, the present invention relates to a method of producing the optical laminate. [Prior Art] A polarizing plate is used as an optical component constituting a liquid crystal display device. In the past, a polarizing plate was used for one surface or both surfaces of a polarizing film, and a protective layer containing a transparent resin film was laminated with a water-based adhesive or the like. As the transparent resin film, a triacetyl cellulose film (TAC film) is used in many cases because of its excellent optical transparency and moisture permeability. When the protective layer is provided only on one side of the polarizing film, in many cases, the resin film having an optical function such as a phase difference function has a protective function of a polarizing film, and is laminated on the polarizing film via an adhesive or an adhesive. one side. The polarizing plate thus constituted may be laminated to the liquid crystal cell by using an adhesive to separate the other optical functional layers. The liquid crystal panel is incorporated in the liquid crystal display device. The liquid crystal display device has rapidly expanded its use as a thin display surface for liquid crystal televisions, liquid crystal monitors, and personal computers. "In the case of this use expansion, the components constituting it are also required to be further thinned. As described above, the polarizing plate is usually attached to the liquid crystal cell by using an adhesive, because the following is convenient: when it is attached When a certain kind of bad condition occurs, it is easy to peel off from the liquid crystal cell and then adhere to other polarizing plates. However, in order to maintain a moderate adhesive force, the adhesive usually needs a thickness of at least about 2 〇μπι. The thinning of the liquid crystal panel or the liquid crystal display device has become a bottleneck. The manufacturer has also attempted to form an adhesive layer directly on the polarizing film by omitting the liquid crystal cell side protective layer of the polarizing film, and bonding the adhesive layer to the liquid crystal cell. However, in the state where the polarizing film and the liquid crystal cell are directly bonded together by the adhesive layer, when the heat resistance test is performed at a high temperature, there is a case where the adhesive layer alone cannot be used. Fully fully absorbs the shrinkage of the polarizing film, and causes problems such as lifting, peeling, and foaming between the polarizing film and the adhesive layer. When a thermal shock test (thermal shock test) which is subjected to a high temperature state and a low temperature state is repeated, there is a case where the stretching of the polarizing film is not sufficiently fully absorbed by the adhesive layer alone, and the polarizing film is cracked. In another attempt to reduce the thickness of the polarizing plate, for example, Japanese Laid-Open Patent Publication No. 2004-245924 discloses a technique of adsorbing at least a polarizing film of a dichroic dye in a polyvinyl alcohol resin. After the uncured epoxy resin composition is applied to one side, the composition is cured to form a protective film. However, the polarizing plate using the cured product of the epoxy resin composition as a protective film is attached via an adhesive. In the state in which the liquid crystal cell is incorporated, the durability is not sufficient. For example, when the thermal shock test is performed, there is a case where the polarizing film is still cracked. Further, the following technique is disclosed in Japanese Laid-Open Patent Publication No. Hei 2-4-245925. : A polarizing film obtained by adsorbing a dichroic dye in a polyvinyl alcohol-based resin, and comprising a ring containing no aromatic ring 148869.doc 201107839 The oxidizing resin is bonded to the protective film as a binder of the composition of the main component to form a polarizing plate. On the other hand, the following technique is disclosed in the Japanese Patent Publication No. Hei 9-159828, on one side of the polarizing plate, Forming a triterpene copolymer contained in an ethylene, an acrylate-based and/or a mercaptoacrylate-based monomer, and maleic acid and/or maleic anhydride, respectively, and formulating a specific amount of a photosensitizer, a propylene-containing oxy group a bonding layer of a photocurable adhesive obtained by an unsaturated compound such as a compound, to form a polarizing plate with an adhesive layer, and a polarizing plate is attached to the liquid crystal cell substrate via the adhesive layer; and is also described in another polarizing film Providing a protective layer containing the above photocurable adhesive on one side. However, when the polarizing plate is attached to the liquid crystal cell substrate via the adhesive disclosed in the document, although in a heat resistance test or a thermal shock test, a small-sized liquid crystal cell is There is no big problem, but the medium to large size liquid crystal cell causes problems such as peeling of the polarizing plate from the surface of the liquid crystal cell substrate or cracking of the polarizing film. Further, a technique of directly feeding a polarizing plate by a roller and bonding it directly to a liquid crystal cell substrate via an adhesive is disclosed in the Japanese Patent Laid-Open Publication No. 2004-4636. [Invention] The object of the present invention is to provide polarized light. The board and the liquid crystal cell substrate are laminated via an adhesive to provide an optical laminate which is thin and lightweight and excellent in durability. Further, another object of the present invention is to provide an advantageous method of producing the optical layered body. The present invention provides an optical laminate comprising: a liquid crystal cell substrate; and a layer which is laminated in contact with a surface of the liquid crystal cell substrate, comprising I48869.doc 201107839 containing an epoxy having at least one epoxy group in the molecule a cured product of the active energy core-curable resin composition of the compound; and a polarizing plate which is laminated in contact with the surface of the adhesive layer, and comprises a polarized light obtained by adsorbing a dichroic dye in a polyvinyl alcohol resin. The film has a thickness of 100 μm or less. In the optical layered product of the present invention, the active energy ray-curable resin composition for forming the adhesive layer may further contain an oxetane-based compound. Further, the thickness of the subsequent layer is preferably 10 or less. The polarizing plate constituting the optical layered body of the present invention preferably comprises a polarizing film laminated in contact with the surface of the adhesive layer, and a transparent protective layer laminated on the opposite side of the polarizing film from the adhesive layer. Further, according to the present invention, there is provided a method for producing an optical layered body, comprising the steps of: polarizing a film comprising a dichroic dye adsorbed in a polyvinyl alcohol-based resin, and having a thickness of 100 μm? An adhesive layer containing an active energy ray-curable resin composition containing an epoxy compound having at least one epoxy group in the molecule is formed on the surface of the plate; and is bonded to the surface of the polarizing plate on the liquid crystal cell substrate. And then irradiating the active energy ray to harden the adhesive layer. According to the present invention, the thickness can be reduced as compared with the prior optical laminate in which the polarizing plate is bonded to the liquid crystal cell substrate via the adhesive, so that the optical laminate, and further the liquid crystal panel, can be made thinner and lighter, and the polarizing plate and the polarizing plate are The adhesion of the liquid crystal cell substrate is also good. Further, by using an adhesive without using an adhesive in the bonding of the liquid crystal cell substrate and the polarizing plate, it is possible to provide an optical laminate which is sufficiently resistant to the heat treatment at the time of assembling the apparatus or the environmental conditions at the time of using the apparatus. The optical laminate of the present invention described above is suitable for use in a large liquid crystal display device such as a television.

When the amount of the photocationic polymerization initiator is less than 5 parts by weight based on 100 parts by weight of the cationically polymerizable compound, the hardening becomes insufficient, and the mechanical strength or adhesion between the polarizing plate and the liquid crystal cell substrate is insufficient. Reduce the tendency. On the other hand, when the amount of the photocationic polymerization initiator is more than 2 parts by weight based on the total amount (10) parts by weight of the cationically polymerizable compound, the hygroscopicity of the cured product is increased due to an increase in the ionic substance in the cured product.

Regarding the blending amount of the photoradical polymerization initiator, the same description as described above for the adhesive layer 2 can be applied. Further, the active energy ray-curable resin composition used in the transparent protective layer 7 may contain other components which are the same as those described above for the adhesive layer 2. The transparent protective layer 7 of the polarizing plate may be a surface treatment such as an anti-glare treatment, a hard coating treatment, an antistatic treatment, or an anti-reflection treatment on the surface opposite to the surface adhered to the polarizing film. Further, a coating layer containing a liquid crystal compound, a high molecular weight compound or the like may be formed on the surface of the transparent protective layer 7 opposite to the surface to be adhered to the polarizing film. In the case where the transparent protective layer 7 is a resin film, an adhesive (adhesive composition) can be used for the adhesion of the polarizing film 6 and the transparent protective layer 7. The adhesive composition to be used for the above-mentioned adhesive composition is not particularly limited, and examples thereof include a curable resin composition containing an active energy ray-curable compound or a water-based adhesive obtained by dissolving or dispersing an adhesive component in water. Among them, it is preferred to use a curable resin composition containing an active energy ray-curable compound because a drying step is not required. When the curable resin composition is used as the adhesive composition, it is usually obtained by bonding the polarizing film 6 and the transparent protective layer 7 via the curing layer to the lipid layer, and then irradiating the composition with the active energy ray. The hardened layer of the phase fat composition is hardened. 148869.doc -34-201107839 The above-mentioned curable resin composition which can be used as the adhesive composition can be the same as the active energy ray-curable resin composition for the liquid crystal cell substrate 1 and the polarizing plate 5 described above. An active energy ray-curable resin composition for the liquid crystal cell substrate 1 and the polarizing plate 5, an active energy ray-curable compound thereof, and the like, and a curing property for the transparent protective layer 7 and the polarizing film 6 The resin composition and the active energy ray-curable compound or the like contained therein may be the same or different. In addition, as a water-based adhesive which is obtained by dissolving or dispersing an adhesive component in water, an adhesive composition containing a polyvinyl alcohol-based resin or a urethane resin as a main component is exemplified. When a polyvinyl alcohol-based resin is used as a water-based adhesive, the polyvinyl alcohol-based resin may be partially saponified polyvinyl alcohol or fully saponified polyvinyl alcohol, or may be a slow-based base. A left-modified polyethylene resin such as a polyethylene glycol, an ethylene glycol-modified polyvinyl alcohol, a methyl-modified polyvinyl alcohol or an amine-modified polyethylene. In the case where a polyethylene glycol component is used, the binder is often prepared as an aqueous solution of polyvinyl alcohol system 2. The concentration of the polyvinyl alcohol-based resin in the subsequent agent is usually about 10 parts by weight, preferably 1 to 5 parts by weight, per 100 parts by weight of water. The adhesive containing a poly-ethylenic resin as a main component is preferably a curable component such as t or a water-soluble epoxy resin or a crosslinking agent to improve the succulent property. Examples of the water-soluble epoxy resin include reacting a poly-molecular polyamine such as diethyltriazine or hydrazine with a dibasic acid such as adipic acid to obtain 4 yoke amines. ' 4 The polyamine amine polyamine ring obtained by reacting the polyamine polyamine with epichlorohydrin is a 'tenthene. As a product of the melamine polyamine epoxy resin 148869.doc -35- 201107839, sold by Sumika Chemtex (Sumirez Resin 65〇) and "Sumirez Resin 675", Japan PMC (shares) "ws_525" and so on can be used appropriately. The amount of the curable component or the crosslinking agent to be added is usually from 1 to 50 parts by weight, based on 100 parts by weight of the polyvinyl alcohol-based resin. If the amount of addition is small, there is a tendency that the effect of improving the adhesion is reduced. On the other hand, if the amount of addition is large, the subsequent layer tends to become brittle. In the case where a urethane resin is used as a main component of a water-based adhesive, 'as an example of a suitable adhesive composition, a polyg-type ionic polymer type urethane resin and a glycidol are mentioned. A mixture of compounds of oxy groups. Here, the polyester-based ionic polymer type urethane sulphate resin refers to a urethane resin having a polyester skeleton and having a small amount of an ionic component (hydrophilic component) introduced therein. The ionic polymer type urethane carboxylic acid resin can be directly emulsified in water to form an emulsion without using an emulsifier, so that it can be suitably used as a water-based adhesive. The polyester-based ionic polymer type urethane phthalate resin is known per se. For example, in the Japanese Patent Application Laid-Open No. Hei 7-97504, a sulphur-based ionic polymer type urethane phthalate resin is contained as an example of a polymer dispersant for dispersing a variegated resin in an aqueous medium. In the Japanese Patent Laid-Open Publication No. 2005-070140 and the Japanese Patent Laid-Open Publication No. 2005-18 1 817, a polyester-based ionic polymer type urethane phthalate resin and a glycidoxy group are disclosed. A mixture of the compounds is used as an adhesive agent to bond a ring-diffuse-type resin film to a polarizing film containing a polyethylene glycol-based resin. &lt;Manufacturing Method of Optical Laminate&gt; 148869.doc -36-201107839 The method for producing an optical layered body of the present invention is applicable to a method for producing the optical layered body of the present invention described above, which comprises the following (丨) Next, the agent layer forming step, and (2) the bonding step, preferably further comprises (3) a hardening step. (1) The adhesive layer forming step is formed on a surface of a polarizing plate (polarizing plate 5) having a thickness of 1 μm or less, which is obtained by adsorbing a polarizing enthalpy of a dichroic dye in a polyvinyl alcohol-based resin. An adhesive layer (adhesive layer 2) for forming an active energy ray-curable resin composition containing an epoxy compound having at least one epoxy group in the molecule for forming the adhesive layer 2; (7) a bonding step, a liquid crystal cell substrate (the liquid crystal cell substrate is similar to the adhesive layer formed on the surface of the polarizing plate 5 by bonding the adhesive layer forming step); (3) a hardening step, and the liquid crystal cell obtained by the bonding step The laminate of the substrate 1 and the adhesive layer 2V polarizing plate 5 is irradiated with active energy rays such as visible light, ultraviolet rays, X-rays, and electron beams to cure the adhesive layer 2. In the manufacturing method, the polarizing plate may be separate. The polarizing film may be a layer in which another layer is laminated as described above, and when a transparent protective layer containing a cured product of the active energy ray-curable resin composition is formed on one surface of the polarizing film, or by containing active energy The adhesive agent of the wire-curable resin composition is laminated, and in the above-mentioned hardening step, the adhesive layer 2 can be cured and cured, or used to bond the polarizing film and the transparent protective layer. In the following, the steps are specifically described. First, in the subsequent sword formation step (1), the surface of the polarizing plate 5 is formed 148869.doc • 37·201107839 to form active energy ray hardenability. In the adhesive layer 2 of the resin composition, the active energy ray-curable resin composition may be directly applied to the bonding surface of the polarizing plate 5 to which the liquid crystal cell substrate 1 is bonded, and dried as needed; or Further, an active energy ray-curable resin composition is applied onto a substrate film containing a transparent resin such as a polyethylene terephthalate, and if necessary, dried, and then the active energy ray-curable resin composition is applied. The method of transferring the coating layer onto the polarizing plate 5, etc. In the case of the latter method, the substrate film is then removed and supplied to the subsequent bonding step. As the substrate film, for example, Polyethylene terephthalate film, polycarbonate film, triethylene glycol film, olefin film, polyester film, polystyrene film, etc. Coating active energy ray-curable resin combination of substrate film The surface of the object may be a peeling treatment. Here, as shown in FIG. 2, for example, a transparent protective layer 7 is provided on a surface of the polarizing film 6 opposite to the side of the liquid crystal cell substrate, and the transparent protective layer 7 includes In the case of a cured product of the active energy ray-curable resin composition, a layer corresponding to the active energy ray-curable resin conjugate of the transparent protective layer 7 is also provided on the surface of the polarizing film 6. The transparent protective layer 7 is used. When the layer of the active energy ray-curable resin composition is formed on another base film and adhered to the Φ of the polarizing film 6, the base film preferably maintains this state until the subsequent hardening step. When the hardening step is finished, it is peeled off. Then, in the σ step (7), the adhesive layer 2 provided on the polarizing plate 5 is attached to the liquid crystal cell substrate, and it is preferable to polarize the liquid crystal cell substrate_reagent layer 27 in the hardening step (7). The laminate which is laminated in the order of the sheet 5 'is irradiated with visible light, ultraviolet rays, X-rays, electron beams and the like. J48869.doc -38·201107839 Energy line' thereby hardens the adhesive layer 2' to obtain an optical layered body. In this case, when the active energy ray-curable resin composition layer for forming the transparent protective layer 7 is provided on the surface of the polarizing film 6 opposite to the liquid crystal cell substrate 1 side, it is preferable that the transparent protective layer 7 is used. The active energy ray-curable resin composition is also hardened at the same time. When the base film is provided on the transparent protective layer 7, the base film is finally peeled off. On the other hand, for example, when the polarizing plate 5 having the transparent protective layer 7 including the resin film is used on one or both sides of the polarizing film 6, the transparent protective layer 7 and the polarizing film 6 are combined by an active energy ray-curable resin. Next, the active energy ray-curable resin composition ' is applied to the joint surface of the transparent protective layer 7 and/or the polarizing film 6 and the layer of the active energy ray-curable resin composition is passed through the layer of the active energy ray-curable resin composition. The film 6 is laminated on the transparent protective layer 7 (resin film), and the same operation as described above is carried out to obtain a laminate in which the liquid crystal cell substrate 丨/adhesive layer 27 is laminated in the order of the polarizing plate 5, and then The adhesive composition may be irradiated with an active energy ray in the same manner as described above. In addition, the optical layered body can be manufactured by the following method: instead of forming the adhesive layer 2| for the liquid crystal cell substrate 1 and the polarizing plate 5 on the surface of the polarizing plate 5, a spin coating method or the like is used. The active energy ray-curable resin composition for forming the adhesive layer 2 is applied to the surface of the liquid crystal cell W and the surface of the polarizing plate, and the polarizing plate 5 is superimposed thereon, and the active energy ray is irradiated to make the active The energy ray-curable resin composition is cured. In addition, the adhesive layer 2 containing the active energy ray-curable resin composition is formed on one surface of the polarizing plate 5 in consideration of the easiness of production, and the (four) layer is bonded to the liquid crystal cell substrate! The latter method of making the subsequent (four) 21 hardening is advantageous. 148869.doc • 39-201107839 The mechanism for applying the active energy ray-curable resin composition forming the adhesive layer or the transparent protective layer to the polarizing plate, the polarizing film or the substrate film is not particularly limited. For example, a doctor blade, Various coating methods such as a wire bar, a slit extrusion coater, a comma coater, and a gravure coater. In addition, since each coating method has its most suitable viscosity range, it is also useful to use a solvent to adjust the viscosity. The solvent used for adjusting the viscosity can be exemplified above. The light source for illuminating the active energy ray is not particularly limited, and can be used for, for example, a low-pressure mercury lamp having a light-emitting distribution at a wavelength of 400 nm or less, a mercury lamp, a south-pressure mercury lamp, an ultra-high pressure mercury lamp, a chemical lamp, a black light lamp, a microwave-excited mercury lamp, Metallic lights, etc. The light irradiation intensity of the active energy ray-curable resin composition varies depending on each composition, but the irradiation intensity of the wavelength region effective for activation of the photocationic polymerization initiator and/or photoradical polymerization initiator is good. It is 1 〇~25〇〇mW/cm2. When the light irradiation intensity of the active energy ray-curable resin composition is less than 丨〇mw/cm 2 , the reaction time becomes too long, and if it exceeds 2500 mW/cm 2 , there is a possibility that heat due to self-lighting and active energy may be generated. When the linear curable resin composition is heated during polymerization, the active energy entangled resin composition is yellowed or the polarizing film is deteriorated. The light irradiation time of the active energy ray-curable resin composition is controlled according to each composition, and is not particularly limited. It is preferably set so that the cumulative light amount of the product of the irradiation intensity and the irradiation time is 10 to 2500 mJ. /cm2. When the cumulative light amount of the active energy ray-curable resin composition is less than mJ/cm2, the active species derived from the polymerization initiator may be insufficient, and the hardening of the obtained adhesive layer may be insufficient. In addition, if the accumulated light amount exceeds 25 〇〇 mJ/cm 2 , the irradiation time becomes very long, which is disadvantageous for improving productivity. Furthermore, the activity of the active energy source is better than that of the polarizing film and the transmittance of the polarizing film are not included in the range of performance degradation of the Wuji Temple. &lt;Liquid Crystal Display Device&gt; In the optical layered bodies 1G to 12 of the present invention, another liquid crystal cell substrate is disposed on the opposite side of the liquid crystal cell substrate and the surface on which the polarizing plate 5 is bonded, and is sandwiched between the two. The liquid crystal can be used to form a liquid crystal cell or a liquid crystal panel. A liquid crystal display device is constructed by using a liquid crystal panel or a liquid crystal panel as a display element. The liquid crystal cell itself in which the liquid crystal is sealed between the two liquid crystal single S substrates can be used as the liquid crystal cell substrate in FIGS. 1 to 3, and the polarizing plate can be bonded to one surface or both surfaces thereof according to the present invention. LCD panel. Since the optical layered body of the present invention is excellent in durability against a thermal shock test or the like, the liquid crystal display device produced in the above manner is also excellent in durability such as a thermal shock test, and is thin and light.
