Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polarizing plate for a liquid crystal display device or the like, and more particularly to a polarizing plate having an antiglare layer on a polarizing film. Further, the present invention relates to a composite polarizing plate and a liquid crystal display device using the polarizing plate. [Prior Art] A polarizing plate is used as an optical component constituting a liquid crystal display device. Conventionally, the polarizing plate which is generally used has a protective layer containing a transparent resin film on one side or both sides of the polarizing film via a water-based adhesive or the like. The transparent resin film 'is excellent in optical transparency or moisture permeability, and a triethylene fluorene cellulose film (TAC film) is often used. The polarizing plate is attached to the liquid crystal cell via an adhesive by other optical functional layers as needed, and incorporated into the liquid crystal display device. In recent years, liquid crystal display devices have been widely used in mobile devices such as notebook personal computers, mobile phones, and car navigation systems. With this, the polarizing plates constituting liquid crystal display devices are required to be thin, lightweight, and durable. strength). Further, the industry expects that a liquid crystal display device for mobile use can be used under moist heat, and a polarizing plate used for the same is required to have high heat and humidity resistance. On the other hand, as described above, a conventional polarizing plate in which a TAC film is bonded to a polarizing film as a protective layer is exposed to a high-humidity environment, particularly in a humid environment, and the polarizing property is lowered, or polarized light is present. The problem of membrane shrinkage. Therefore, for the protective layer deposited on the polarizing film, it is required to quantify the thin punch, and to increase the hardness of the south, the mechanical strength of the south, and the ability to suppress the shrinkage of the polarizing film (shrinkage inhibition force). However, in the case of a polarizing plate in which a TAC film is bonded as a protective layer, it is difficult to make the thickness of the protective layer 20 μm or less from the viewpoint of the workability or the long-term performance at the time of operation. As a technique which can solve the above-mentioned problem, for example, Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. The technique of the layer is disclosed in Japanese Laid-Open Patent Publication No. H20-185842 (Patent Document 2), which is an energy-polymerizable compound containing a dicyclopentyl residue or a dicyclopentene residue. A technique for forming a protective film on a polarizing film by hardening a wire-curable composition, and a method of forming an epoxy resin on at least one side of a polarizing film is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. 4-245924 (Patent Document 3). A polarizing plate made of a protective film of a main component is disclosed in Japanese Laid-Open Patent Publication No. 2005-92112 (Patent Document 4), which is characterized in that at least one side of the polarizing film is protected by a cured product of the active energy ray-curable resin composition. On the other hand, if the external light is reflected in the polarizing plate constituting the liquid crystal display device, the visibility is remarkably impaired. Therefore, the surface of the image display device has been previously used to prevent such external light from being reflected. The film layer for preventing external light from being reflected. The film layer for preventing reflection is usually treated by non-reflection treatment using interference of the optical multilayer film' or II, because the surface is formed with fine sunburst to scatter the incident light to cause the image to be reflected. In particular, the anti-glare treatment layer which scatters incident light by forming fine concavities and convexities is widely used for large monitors or personal computers, and is widely used for applications such as large monitors and personal computers. The anti-glare film of the anti-glare treatment is produced by, for example, the following method 149176.doc 201109747 or the like: coating a resin solution in which a filler is dispersed on a substrate sheet, and coating the thickness of the coating film to expose the filler to The surface of the film is coated to form random irregularities on the substrate sheet. On the other hand, there is also an attempt to exhibit anti-glare properties only by the fine concavities and convexities formed on the surface of the transparent resin layer without containing a filler. Japanese Laid-Open Patent Publication No. 2002-189106 (Patent Document 5) discloses an anti-glare film in which a state in which an exothermic radiation-curable resin is interposed between an embossing mold and a transparent resin film is disclosed. The free radiation curable tree is known to be hardened to form a three-dimensional 1 〇 point average roughness and an average distance between adjacent convex portions on the three-dimensional thickness reference surface respectively satisfies a specific value of fine unevenness, whereby the layer is laminated on the transparent resin film. A cured layer of a free-radiation curable resin having a surface unevenness. Further, as a embossing method of obtaining a different type of anti-glare film, the use of the disclosed method disclosed in Japanese Laid-Open Patent Publication No. 2006_53371 (Patent Document 6) is also known. A method of plating a mold layer, etc. However, a conventional anti-glare treatment is applied to a transparent resin film as a protective layer of a polarizing plate, and a polarizing plate having the above anti-glare film laminated thereon does not satisfy the liquid crystal display device of recent years.

The ionic compound having an organic cation and the ionic compound having an I cation exemplified above have a counter ion (anion), respectively. Therefore, the above-mentioned examples of the ionic compound having an organic anion and the ionic compound having the anion of I 149176.doc 41 201109747 can be used to constitute the cation compound and the ionic component of the ionic compound in the compound disclosed above. Particularly preferably, in the case of having a pyridyl group, the anion component constituting the ionic compound allows the fluorine atom to provide an ionic compound which is excellent in antistatic properties, and is particularly lightly bismuth (fluorosulfonyl) fluorene. Imine anion [(fs〇2) 2N-]. The conductive fine particles which can be an antistatic agent are usually inorganic particles having conductivity, and examples thereof include tin oxide doped with antimony, doped tin oxide, antimony oxide, antimony acid, titanium oxide, and oxidation. Zinc, ιτ〇 (Indium Tin Oxide), etc. The conductive polymer which can be an antistatic agent is, for example, polyaniline, polyfluorene, polyacetylene or polythiophene. Among the antistatic agents described above, it is preferred to use an ionic compound in terms of excellent phase contrast with the active energy ray-curable resin composition. The antiglare layer and the protective layer provided on the polarizing plate of the present invention preferably have optical transparency. Therefore, it is preferred that the antistatic agent used does not cause light scattering or the like, and does not inhibit the antiglare layer and the protective layer. Optical transparency. The antistatic agent is preferably blended in an amount of from 0.5 to 20 parts by weight, based on 1 part by weight of the active energy ray-curable resin composition containing the active energy ray-curable compound and the photopolymerization initiator. It is 2 to 15 parts by weight, more preferably 疋 4 to 1 part by weight. If the amount of the antistatic agent is less than 5% by weight based on 1 part by weight of the active energy curable resin composition, it becomes difficult to obtain sufficient antistatic property. On the other hand, if the amount of the antistatic agent 149176.doc • 42·201109747 is more than 20 parts by weight relative to the active energy ray-curable resin combination (9) by weight, the polarizing film and the antiglare layer may be protected and/or protected. The thickness of the layer is the same as that of the electrostatic agent. The optimum amount of the electrostatic agent varies depending on the type of the antistatic agent to be used or the type of the active energy ray-curable compound, and therefore it is preferable to use The surface resistivity of the obtained antiglare layer and/or the protective layer is 1 Χ 1012 Ω/□ or less, and further 1 χ 1 〇 11 Ω/□ or less, and the amount of the adjustment is adjusted within the above range. Further, the active energy ray-curable resin composition may contain a solvent as needed. The solvent can be appropriately selected by reducing the solubility of the components constituting the active energy ray hardening (iv) fat composition. Examples of the solvent to be used generally include aliphatic hydrocarbons such as hexanyl or cyclohexane; aromatic hydrocarbons such as toluene or xylene; methanol, ethanol, propanol, isopropanol and n-butanol. Alcohols such as ketones such as propyl ketone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone; acetic acid " vinegar such as ethyl acetate and butyl acetate; A cellosolve such as a cellosolve, an ethyl cellosolve, or a cellosolve such as butyl cellosolve, or a southern hydrocarbon such as chloroform. The ratio of the solvent to be blended is appropriately determined depending on the viewpoint of viscosity adjustment based on processing purposes such as enthalpy. The thickness of the antiglare layer and the protective layer are preferably 2 or less in terms of thinness, lightness, protection function, workability, and the like. Further, the thickness of the antiglare layer having irregularities refers to the linear distance between the apex of the unevenness and the bottom surface (the surface on the polarizing film side). These thick products can be obtained by using the contact film thickness shown in the following examples.敎 敎 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = 43-201109747 The thickness of the anti-glare layer or the protective layer is obtained by microscopic observation. The unevenness of the surface of the anti-glare layer allows the anti-glare layer to exhibit the following optical characteristics (anti-glare property) by means of the following A well-known method is suitably formed. (Optical characteristics of a polarizing plate) The polarizing plate of the present invention in which the above-described anti-glare layer is directly formed on one surface of a polarizing film, and is effectively suppressed from being applied to a high-definition image display device in order to prevent whitening The glare of the time, the total haze is preferably 5 to 25 ° /. The total haze can be measured according to the method shown in JIS κ 7136. If the total haze exceeds 25%, when applied to an image display device, As a result, the picture becomes darker, which is detrimental to visibility, so it is not good. 'If it is less than 5%, it is difficult to exhibit sufficient anti-glare property. Regarding the polarizing plate of the present invention, three types of optical combs having a width of 〇5 mm, 1.0 mm, and 2.0 mm in the dark portion and the bright portion are used for incident light. The sum of the reflection sharpness measured at the angle 45 较好 is preferably 4% or less. The reflection sharpness is measured by a method defined in JIS K 7 105. In this specification, as an optical comb used for image sharpness measurement, It is defined as a ratio of the width of the dark portion to the bright portion of 1, 1. The width is 0125 mm, 0.5 mm, 1.0 mm, and 2.0 mm. Among them, when using an optical comb having a width of 0.125 mm, As a film having fine irregularities formed in the anti-glare layer, since the error of the measured value becomes large, the measurement value in the case of using the optical comb having a width of 〇·125 mm is not added to the sum, and the width 〇 5 mm is selected. The sum of the sharpness of the image measured by the claws and the three kinds of optical combs of 2.0 mm is called the reflection resolution. The maximum value of the reflection resolution in the case of this definition is 3〇〇%. If the degree exceeds 40%, the image of the light source and the like will be clearly reflected. 149176.doc •44· 201109747 (Manufacturing method of polarizing plate) A method of manufacturing a polarizing plate having an anti-glare layer on one side of a polarizing film is particularly limited, and can be used previously. For example, there is a method in which an active energy ray-curable resin composition in which a filler (translucent fine particles) is dispersed is applied onto a polarizing film, and the thickness of the coating film is adjusted to expose the filler to the surface of the coating film. A method of forming random irregularities; or a method of exhibiting anti-glare properties only by fine irregularities formed on the surface of a coating film without containing a filler. The active energy ray-curable resin composition in which the filler is dispersed is coated by hunting. In the case where the antiglare layer is formed on the polarizing film, the filler is not particularly limited as long as it is translucent, and conventionally known inorganic or organic particles can be used. For example, examples of the inorganic fine particles include carbonic acid, barium sulfate, titanium oxide, hydrogen peroxide, cerium oxide, glass, talc, mica, white carbon, magnesium oxide, zinc oxide, and the like. And a surface treatment of the inorganic particles by a fatty acid or the like. Further, examples of the organic fine particles include melamine beads, polymethyl methacrylate beads, decyl methacrylate/stuppy ethylene copolymer resin beads, polycarbonate beads, and polyethylene beads. Resin particles such as polystyrene beads and polyoxyxene beads. Further, the particle diameter of the filler is, for example, in the case of using inorganic fine particles such as cerium oxide, and the weight average particle diameter is preferably in the range of 〜1 to 5 μηι, for example, in the case of using resin particles, the weight average particle. The diameter is preferably in the range of 2 to 10 μη. A method of exhibiting anti-glare property by the fine unevenness formed by the surface of the coating film is not included. For example, as disclosed in Japanese Laid-Open Patent Publication No. 2006-5337 (Patent Document 6), fine irregularities can be used. Shape mold, 149176.doc -45- 201109747 Transfer the surface shape of the mold to the coating film. The transfer of the surface shape to the coating film is carried out by embossing. The υν embossing method forms a coating layer (active energy ray-curable resin composition layer) of the active energy ray-curable resin composition on the surface of the polarizing film, and presses the active energy ray-curable resin composition layer to the above-mentioned The uneven surface of the mold of the fine unevenness is simultaneously hardened, whereby the uneven surface of the mold is rotated to I3 to activate the layer of the linear curable resin composition. Specifically, the active energy ray-curable resin composition is applied onto the polarizing film, and if necessary, dried, and the active energy ray-curable resin composition layer obtained is adhered to the uneven surface of the mold. The active energy ray-curable resin composition layer is cured by irradiation with an active energy ray such as visible light, ultraviolet ray, xenon ray or electron beam, and secondarily, the cured active energy lining resin composition layer is formed from the mold. The polarizing film is peeled off, whereby the shape of the mold is transferred to the coating layer of the active energy ray-curable resin composition. Further, as another method of the method of containing the filler and only the fine unevenness formed on the surface of the film to exhibit the anti-glare property, the shape of the shaping film may be changed by using the shaping film having fine irregularities on the surface. A method of printing onto a coating layer (active energy ray-curable resin composition layer) of an active energy ray-curable resin composition. Specifically, the above-mentioned active energy ray-curable resin composition is coated on the uneven surface of the coating film having flexibility and at least one surface having fine irregularities, and it is necessary to dry it, and the coated surface is a bonding surface. The method is to bond it to the polarizing film. Then, the coating film containing the active energy ray-curable resin composition is cured by irradiating the laminated body with an active energy ray, and then the above-mentioned forming film is peeled off, and the unevenness is transferred to the polarized light 149176.doc-46· 201109747 The coating on the surface of the film. Further, the active energy ray-curable resin composition may be directly applied to a polarizing film, dried as necessary, and applied to the uneven surface of the above-mentioned shaped film so that the coated surface thereof becomes a bonding surface, and The same method as described above performs hardening of the active energy ray-curable tree residue layer and peeling of the forming film. Here, as the shaping film, a polyethylene terephthalate film, a polycarbonate film, a triethylene glycol film, a pentene resin film, a polyester film, a polystyrene film or the like can be used. The coating method of the active energy ray-curable resin composition is not particularly limited. For example, various coatings such as a doctor blade, a wire bar, a die coater, a kama coating machine, and a gravure coater can be used. the way. Further, a method in which the active energy ray-curable tree smear and the S material are dropped between the polarizing film, the mold, or the shaping film, and then pressurized by a roller or the like is uniformly spread. In the case of the material of the roll, metal or rubber can be used. Moreover, when a method in which the active energy ray-curable resin composition is dropped between a polarizing film, a mold, or an adhesive film by a roller and a newspaper is applied and pressurized, and the method is carried out, The two rollers can be of the same material or different materials. In the case of the local moon, the protective layer containing the cured product of the active energy ray-curable resin composition on the opposite side of the polarizing film from the anti-glare layer can be used in the same manner as in the case of providing the above-mentioned anti-glare layer. method. Here, it is not necessary to use a mold having a fine uneven shape or a forming film, and a smooth roll or a smooth base film can be used. The anti-glare layer is formed on one side of the polarizing film 149176.doc -47-201109747, and when the protective layer is formed on the other side, the order may be to form a protective layer after forming the anti-glare layer, or vice versa. At the same time. Among them, in consideration of the production steps, it is preferable to form the antiglare layer and the protective layer simultaneously on both surfaces of the polarizing film. In this case, when the active energy line is irradiated so that the coating film on the opposite side of the irradiation side can be sufficiently cured, it can be irradiated only from one side of the laminated body, or can be irradiated from both sides of the laminated body. In the case of curing by irradiation with an active energy ray, the light source to be used is not particularly limited, and for example, a low-pressure mercury lamp, a medium-pressure mercury lamp, a high-pressure mercury lamp, an ultra-high pressure mercury lamp, a chemical lamp having a light-emitting distribution with a wavelength of 400 nm or less can be used. , black light tube, microwave excited mercury lamp, metal _ crystallization lamp, etc. The irradiation intensity of the active energy ray-curable resin composition varies depending on the composition. The irradiation intensity of the wavelength region which can effectively activate the photocationic polymerization initiator and/or the photoradical polymerization initiator is preferably 1 〇~2500 mW /cm2. When the light irradiation intensity of the active energy ray-curable resin composition is less than 10 mW/cm 2 , the reaction time becomes too long, and if it exceeds 2500 mW/cm 2 ', it may be due to self-light radiation heat and active energy ray hardenability. The heat generation at the time of polymerization of the resin composition m is yellowing of the active energy ray-curable resin composition or deterioration of the polarizing film. The light irradiation time of the active energy ray-curable resin composition is controlled for each composition, and is also not particularly limited. The total amount of light expressed in the form of the product of the irradiation intensity and the irradiation time becomes 1疋~25〇〇mJ/cm2 is used for the certification. If the integrated light amount of the active energy ray-curable resin composition is less than 10 mJ/em', the production of the active material derived from the polymerization initiator may be insufficient, and the obtained anti-glare layer and/or the protective layer may be hardened. Become inadequate. 149176.doc -48- 201109747 Further, if the cumulative amount of light exceeds 2,500 mJ/cm2, the irradiation time becomes extremely long, which is disadvantageous for productivity improvement. Further, it is preferable that the active energy ray is irradiated in a range in which various properties such as the degree of polarization and transmittance of the polarizing film are not lowered. (Composite polarizing plate) In the present invention, when an anti-glare layer is formed on one surface of the polarizing film and a protective layer is formed on the other surface, as shown in FIG. 3, a layer may be laminated on the outer surface of the protective layer as needed. The composite plate is made into a composite polarizing plate. Here, the phase difference plate is used to compensate for the phase difference of the liquid crystal cell and the like. As an example, a birefringent film including a stretched film of various plastics, a disk in which a discotic liquid crystal or a nematic liquid crystal is fixed, and a liquid crystal layer formed on the film substrate may be mentioned. In this case, it is preferred to use a cellulose film such as tris(tetra)cellulose as a film substrate supporting the alignment liquid crystal layer. Specific examples of the plastic forming the birefringent film include polyolefins such as polycarbonate, polyvinyl alcohol, polystyrene, polymethyl methacrylate, polypropylene, (tetra) olefin resin, and polyaryl 0. Purpose, polyamine, etc. The stretch film can be processed by using a single-axis or two-axis (four) process. X may be a birefringent film which applies a contraction force and/or an extension force in a state in which the heat-reducing film is next, thereby controlling the refractive index in the thickness direction of the film. Further, in order to control optical characteristics such as wide banding, two or more phase difference plates can be used in combination. When the protective layer has an adhesive force to the retardation film, the bonding of the phase difference plate to the material layer may be performed by directly bonding the two, or may be performed by using a dot or a dot. The phase difference plates can also be used in conjunction with each other. In view of the simplicity of the work or the prevention of optical strain I49176.doc -49- 201109747, it is preferable to use an adhesive (also known as a pressure-sensitive adhesive) as an adhesive, and an acrylic system can be used. As the base polymer, a polymer, a polyoxymethylene polymer, a polyester, a polyamino phthalate, a polyether or the like. Among them, it is preferable to use an adhesive such as an acrylic adhesive, which is excellent in optical transparency, maintains moderate wettability or cohesive force, and excellent in adhesion, and further has weather resistance or heat resistance, and is heated or humidified. There is no problem of peeling such as bulging or peeling. In the propionic acid-based adhesive, the glass transition temperature is preferably 25 ° C or lower, more preferably ruthenium.

An acrylic copolymer having a weight average molecular weight of 100,000 or more, such as a functional acrylic monomer, can be used as a base polymer. Further, the phase difference plate can be directly used in the composite polarizing plate of the present invention. It is also possible to perform a corona discharge treatment, a plasma treatment, or the like on the bonding surface with the protective layer, and then it is applied to the protective layer. (Adhesive layer) Further, on the polarizing plate of the present invention The adhesive layer may be provided, for example, for bonding to a liquid crystal cell, bonding to the phase difference plate, and bonding to other layers. The adhesive may be an acrylic polymer or a polyoxygen. It is a polymer, polyester or polyamino phthalate, agglomerate, etc. as a base polymer. Among them, it is preferred to use an adhesive such as an acrylic adhesive, which is excellent in optical transparency and maintains moderate wettability or Cohesiveness and excellent adhesion Further, it has weather resistance, material properties, etc., and does not cause peeling problems such as bulging or peeling under heating or humidifying conditions. In the acrylic adhesive 149176.doc 201109747, the glass transition temperature is preferably 25 ° C or less. More preferably, the alkyl (meth)acrylate having an alkyl group having 2 or less carbon atoms such as a mercapto group, an ethyl group or a butyl group, and the (meth)acrylic acid or (meth) An acrylic copolymer having a weight average molecular weight of 100,000 or more, which is a functional group-containing acrylic monomer such as hydroxyethyl acrylate, can be used as the base polymer. The adhesive layer can be formed, for example, by the following And the adhesive composition of the base polymer or the like as described above is dissolved or dispersed in an organic solvent such as hydrazine or ethyl acetate, and a solution of 1 〇 to 4 〇% by weight is prepared to form a pre-adhesive bond on the protective film. The agent layer is transferred to a polarizing plate to form an adhesive layer. The adhesive is preferably one using the above acrylic polymer as a base polymer, etc. The thickness of the adhesive layer is based on the adhesion thereof. It is determined that it is usually in the range of 1 to 50 μm.
