Description

The present invention relates to a kit for a polarizing plate for a liquid crystal panel, and a liquid crystal panel and an L display of the set of the polarizing plate. [Prior Art] ο The components of the liquid crystal panel, which are the main components of the polarizing plate-based liquid crystal display, are usually formed on one or both sides of a polarizing film composed of polyethylene-resin adsorbed with a two-color pigment and oriented. Next, a protective film (for example, a transparent cellulose acetate film represented by divinyl cellulose) is used. If necessary, the polarizing plate may be attached to the liquid crystal cell via another optical film and an adhesive to obtain a liquid crystal and a plate.液晶 The LCD monitor system is rapidly expanding its use as a thin display for LCD TVs, LCD screens, and personal computers. In particular, the market for LCD TVs has expanded significantly and the demand for cost reduction has been very strong. As a polarizing plate for a liquid crystal television, it has been conventionally used as a water-based adhesive laminated aluminum oxide film (TAC film) which is used on both sides of a polarizing film composed of a thin film of polyvinyl alcohol resin, and is used for the polarizing plate. The retardation film is adhered to one side via an adhesive. As a retardation film laminated on a polarizing plate, generally, a stretched processed material of a polythene carbonate sapphire film or an extended processed product of a ring-dark smoky resin film is used, but in the case of a liquid crystal television, most of them are used. A retardation film made of a cycloolefin resin film having a very small phase difference at a high temperature. In the case of a laminate of a retardation film composed of a polarizing plate and a stretched olefin resin film, in order to improve productivity and reduce product cost, efforts are being made to reduce the number of components and simplify the manufacturing process. For example, Japanese Patent Publication No. 320817 3 200932524 (Japanese Patent Publication No. Hei No. 8-43812 (Patent Document No. 4) The TAC film is directly laminated with a cyclic olefin (norbornene) grease film having a phase difference function. [Problems to be Solved by the Invention] In addition, in the use of large-screen LCD TVs, for example, as a wall-mounted electric squinting application, the demand for further reduction in thickness and weight of liquid crystal displays is becoming remarkable.

For example, the stretching ratio is preferably in the range of j. 〇 5 times or more 丨 6 times or less, and is preferably set to 1.1 times or more, or preferably set to L 5 times or less. When the biaxial stretching is performed, the stretching ratio in the maximum extending direction may be within the above range. When the thickness d of the stretched cycloolefin resin film is too thick, the processability is deteriorated, and the transparency is lowered or the weight of the polarizing plate is increased. Thus, the thickness d of the stretched cycloolefin resin film is preferably from about 4 Å to about 80 Å.

When the amine group is modified by the polybthrene component, the binder is made of Honda Ethanol resin as the polyethylene __: the water-soluble sputum of St is usually about 1 to 10 parts by weight, and the weight of the water is 100. It is preferred that the polyetheranol has a tree frequency of from 1 to 5 parts by weight. In the adhesive of the knife, in order to mention 320817 20 200932524 high adhesion, it is preferable to add a hardening property such as a water-soluble epoxy resin or a crosslinking agent. The water-soluble epoxy resin may, for example, be an epichlorohydrin, a polyamine which is obtained by reacting a poly-anthracene polyamine such as diethylenetriamine or triethylenetetramine with a di(tetra) acid such as adipic acid. Polyamine transamine epoxy resin obtained by amine reaction. "SumirezResin65^ "Sumirez Resin 675" sold by the company of the polyamine-polyamine epoxy resin, such as Sumitomo's "Resin 65", by R.

The amount of such a curable component or a crosslinking agent is 50,000 parts by weight based on the polyvinyl alcohol resin (10) by weight. When the amount of the knife is 1 to 100, the amount of addition is small, and the effect of improving the adhesion is reduced. On the other hand, if the rotation is performed, the adhesive layer tends to become brittle. In the case of using a poly-resin resin as a main component of the adhesive, examples of the composition of the composition include, for example, the binder of the Biantian and the t-ion polymer type polyamine vine; a mixture of compounds having an oxypropoxy group. Here, the so-called sub-polymer (i〇n〇mer) type of polyacetal vinegar is used as an amine vinegar resin, and is introduced into the right small 1 system.

Polyurethane resin with a glycidoxy A mixture of the compounds is used as an adhesive agent to form a film of a cycloolefin resin bonded to a polarizing film made of a polyvinyl alcohol resin. A photocurable adhesive can also be used as the adhesive. The photocurable adhesive can be exemplified by a mixture of a photocurable epoxy resin and a photocationic polymerization initiator. A method of bonding an extended polyethylene terephthalate film and/or a transparent film to the surface of the first polarizing film by using an adhesive can be carried out by a conventional method, for example, by flow casting or wire coating. Coating method, gravure coating method, comma coating method, doctor blade method, die coating method, dip coating method, spray method, etc., applying an adhesive to the second polarizing film And/or a method of adhering the two to each other after bonding the film to the surface of the film. The term "flow casting method" refers to a method in which a thin medium as a coated object is moved in an approximately vertical direction, a horizontal direction, or an oblique direction therebetween, and an adhesive is allowed to flow down and spread on the surface thereof.涂布 After applying the adhesive as described above, the second polarizing film and the thin film bonded thereto are sandwiched by a nip roll or the like to be bonded, and the two test pieces are joined. Further, a method of dropping the adhesive between the first polarizing film and the film bonded thereto may be suitably employed, and then the laminate is pressure-wisely pressed to uniformly swell the adhesive. At this time, the material of the roller can be metal or rubber. And 'preferably, after the adhesive is dropped between the ith polarizing film and the film bonded thereto, the laminated body is passed between the roller and the roller, and the adhesive is uniformly dispersed. method. In this case, the rolls can be of the same material or different materials. &quot; 22 320817 200932524 Ingredients 2 Thickness === After the above-mentioned disappointing and the like, the following is preferred, and G GUm or above is preferred. In the above, the first polarizing film and/or the surface to be bonded thereto may be appropriately subjected to an electrical dressing process, a corona treatment, a purple line, a shot treatment, a flame treatment, and a chemical treatment. The layered body joined by the water-based adhesive is applied to the dry layer and hardened. The drying treatment can be carried out by way of example (two people hot air. The drying temperature is suitably selected from the range of 4G to (10). The left and right sides of the C are right to the boot). The drying time is, for example, 20 to L coffee ", 竣 = = thickness of the agent layer, and usually _ heart is / / is _ or more, and more preferably 2 &quot; m or less, the appearance is apt to change. When the material is connected to (4), the polarizing plate and the shaft can be applied at a temperature above room temperature for at least half a day, and the above health can be obtained to obtain sufficient adhesion strength. In the state of _, it is better to raise the range of 30 to 5 ,, and to be at 35. 〇 above 45. 0 = = right = the domain exceeds 5 rc when the er In addition, the humidity during health maintenance is not limited to the second dimension. The humidity is preferably in the range of _ to 7_. The time is raised;,: usually from 1 day to 10 days, and from 2 days to 7 days. On the other hand, when the polarizing film is bonded to the film of 320817 23 200932524 by a photocurable adhesive, after bonding, the photocurable adhesive is cured by irradiation of the active energy ray. The light source of the sizing line is not particularly limited, and has an active energy of a luminescent distribution below _nm For better specific, Lu should use low-pressure mercury lamp, medium-pressure mercury lamp, high-pressure mercury lamp, ultra-high pressure mercury lamp, chemical lamp, black button, microwave excited mercury lamp, Ο 〇 metal (four) lamp, etc. Light intensity of light hardening and then riding light According to the photohardenability, the composition is (4) when the mosquito, the money is limited, and the irradiation intensity in the wavelength region effective for the activation of the polymerization initiator is preferably 〇1 to 60〇〇mW/cm2.

In the case of photohardening, the silking time of the illuminating agent is not limited to the individual (four) of the cured photohardenable agent. It is preferable to set the integrated light amount of the product between the irradiation intensity indicated as the attack and the photograph (4) to be 1〇 to 〇j) 〇nJ/Gm2. The cumulative value of t to the photo-curing-turning riding light = lGm; /em2m , the active species derived from the polymerization can be produced in an amount sufficient to The hardening reaction can be carried out more reliably. When it is _/7 or less, the irradiation time does not become too long, and good production can be maintained. Further, the thickness of the adhesive layer after the active energy ray is irradiated is usually = to the left and right, preferably 〇·心u, and more preferably, below l#m.

(Second polarizing plate) The second polarizing plate is used as a polarizing plate on the front side (viewing side) of the liquid crystal panel, and the user's one side of the second polarizing film made of polyethyl acetate An anti-glare film having a haze value of 5% or more and 80% or less is formed. Specifically, the second polarizing thin layer is obtained by orienting a dichroic dye by a uniaxially stretched conjugated film of a bismuth alcohol, and the same can be used for the first polarizing film. The first polarizing film and the second polarizing film may be the same or different in shape (thickness, etc.), material quality, manufacturing method, and the like. The antiglare film described above has at least a stretched polyethylene terephthalate film. By using the stretched polyethylene terephthalate film as a protective film for the second polarizing film, the mechanical strength of the liquid crystal panel can be further improved, and the liquid crystal panel can be further reduced in thickness. In addition, since a polyethylene terephthalate film is also used as a protective layer in the second polarizing plate, the protective film used for the second polarizing plate and the protective film used for the second polarizing plate are used. The same material is used to prevent deflection of the liquid crystal panel. Thereby, even when used in a thin liquid crystal display, it is possible to prevent the circular shape unevenness and the Newton ring caused by the contact of the liquid crystal panel with the backlight system. The extended poly(ethylene dicarboxylate) film may be a uniaxially stretched film or a biaxially stretched film. The second polarizing plate, the extended polyethylene terephthalate 25 320817 200932524 acid ethyl vinegar film can also be used in the above-mentioned extended polyethylene terephthalate film used for the first polarizing plate. . The method for producing the polyethylene terephthalate film is not particularly limited, and a conventional method can be employed. The method for producing a uniaxially stretched polyethylene terephthalate film can be carried out by the above method. Further, the biaxially-oriented polyethylene terephthalate film may be the same or different depending on the shape (thickness of the film, etc.), the material (with or without mixed fine particles), and the production method.厚度 The thickness of the polyethylene terephthalate film is preferably from about 20 to 60/zm, preferably from 30 to 50 amps. When the thickness of the extended polyethylene terephthalate film is less than 20 Å, there is a tendency to be difficult to handle, and if the thickness exceeds 60/zm, the advantage of thinning tends to be small. The haze value of the above-mentioned antifoaming film is in the above range and is preferably 15% or more and 45% or less. By making the haze value of the antifoaming film in the range of 15% or more and 45% or less, the extended poly(ethylene dicarboxylate film) used in the first polarizing plate can be improved and used in the second layer. The color difference of the polyethylene terephthalate film which is extended by the polarizing plate causes unevenness in color when viewed obliquely, and provides a liquid crystal display excellent in visibility. When the haze value of the antifoaming film is less than 5%, sufficient effect of preventing color unevenness cannot be obtained, and if it is higher than 8〇%, the kneading surface becomes white and the visibility is lowered. Here, the haze value of the antifoaming film is measured by a method in accordance with JIS K 7136. Further, the method of imparting the haze in the above range to the antiglare film is not particularly limited, and for example, .-.__.
