The above and other objects and advantages of the present invention will be more apparent and will be hereinafter described in the following preferred embodiments; and the detailed description will be made in conjunction with the related embodiments. [Embodiment] The following is a simplification of the present invention. The second embodiment will be described with reference to Figs. 1 to 5 . However, the parts that are not required for the system are omitted, and those that are shown in the form of enlargement or reduction are easy to be seen. The method for producing the film laminate of the present invention will be described below with a bias = ❹. The present invention is a perspective view for explaining a method of manufacturing a polarizing plate according to the present invention. Fig. 2 is a side view showing a method of manufacturing the polarizing plate, and Fig. 3 is an enlarged view showing an enlarged view of the drawing. Fig. 4A is a view of the shape of the wire with respect to the portion of the suction nozzle opening σ. Figure 5 is a representation of the polarizing plate of the actual compensation _ as shown in Figure 1 and Figure 2, first, in the material _ = two enough 15 'pif.doc to configure the protective film (other film state. This state and protective film In the direction of the polarizer 1 above, the vertical direction is added in the vertical direction, and the polarizer 1 and the protective film 2 are transferred from the same figure to the case where the invention is not necessarily applicable to the horizontal direction. In the case of the directional direction, the protective film 2 may be used in a wide range of production, and it may be changed. The widened sounder of the polarizer 1 and the excess length 9 in the direction may also be used. The use of the isomorphism with the photon = == is not limited to this, and the protection thin "2 details depends on the (four) 4 phase. For the polarizer! In the polarizer 1 and the protective film 2 person supply nozzle (10) liquid supply means = 'The nozzles 11 are placed in the polarized liquid 7 3 ° (four) agent liquid supply, and the mouth method is 'Lin _ plus (four) (for the liquid supply 3 for the ▲ position | 』 抓 抓 抓 抓 抓 抓 抓 抓Ice ~ The system is not specifically limited, according to the need to add: insert: column 'in the close part of the fit, also The adhesive layer 3 can be cut from the vicinity of the center of the width direction, and the bonding portion of the bonding liquid 3 can be cut from the health film 2 so that the bonding liquid 3 flows to the surface to be dripped, and it is required to be dripped, and the protective film 2 is required. The η is inclined at a predetermined angle from the upper side. The position system can also be a plurality of places. The 黏 and the 'dropping film of the bonding liquid 3 series' are left in the photoreceptor or the protective thin to form a liquid retention 12 . Through the liquid stagnation, etc., each of the precursor 1 and the protective ruthenium film 2 can be applied to the supply amount of the adhesive solution 3, and the supply speed, etc., according to the viscosity used. The type of the liquid contact 3, the viscosity, and the like are appropriately set to an optimum value. The adhesive system constituting the adhesive liquid 3 is not particularly limited, and various conventional ones can be used. For example, polyvinyl alcohol (p〇lyvinyl alcohol) can be used. Adhesive, polyurethane adhesive, isocyanate adhesive 'The above polyvinyl alcohol adhesive and boric acid (b〇ric acid), stone sand (borax), pentylene Water solubility of _(giutaraidehyde), melamine and oxalic acid Adhesive agent composed of a bridge agent, etc. When considering the best adhesion to the polarizer 1, it is preferred to use polyvinyl alcohol. The average degree of polymerization of the polyvinyl alcohol is 1 〇〇〇 5 〇. Preferably, it is preferably 1500 to 4000. Further, the degree of saponification is preferably 90 to 1 Torr (m 〇 1). The solvent system constituting the bonding liquid 3 is generally exemplified by water, etc. Other additives, acids, etc. may be blended as needed. Further, an adhesive may be used for the configuration of the above-mentioned adhesive liquid 3. The adhesive system is not particularly limited, and various conventional ones may be employed. Further, the viscosity of the above-mentioned adhesive liquid is in the range of 1 to 100 μmpa.s, and is preferably in the range of 1 to 100 mPa.s. In the above range, the adhesive liquid easily flows out to the end portion of the protective film 2, and the effect of the present invention can be easily obtained. In the case of the adhesive liquid 3 which flows to the both ends of the protective film 2, the night body 6 is supplied from the both end sides of the protective film 2 to the central portion in the width direction. The supply of the liquid 6 is carried out using a supply nozzle (a liquid supply means). The supply nozzles 5 are disposed on the left and right sides of the protective film 2. This is a mode in which the polarizer 1 and the protective film 2 are parallel to the horizontal direction. 13115 god if doc := right: also horizontal relationship, excess adhesive film 2 to pour ==== but 'polarizer 1 and protection thin ρ.Λ§ΛΟ, 'Party configured %5 or a pair When the drum 4 (described later) is tilted, the hybrid part is also applied according to the tilting condition, "," the adhesive liquid 3 flows to one side. Therefore, the supply nozzle is only allowed to be private, " (10) In the case where the /I f is below the liquid 3, it is sufficient. The liquid 6 U flows toward the both ends of the film 2

In the range (4) of the excess length section 9, it is possible to prevent leakage of the residual 3 . The amount of spit out of '3'. The discharge pressure system needs to be able to cover the adhesive liquid and the rim. When the discharge amount of the liquid 6 is more than necessary, the adhesive liquid 3 is diluted to cause a low drop in the adhesiveness. Further, the discharge direction of the liquid 6 is limited to the central portion in the width direction, and various changes may be made in the range in which the adhesive liquid 3 may be blocked. Here, the supply nozzle 5 is provided such that the supply port 7 is positioned inward in the width direction from the left end side of the protective cymbal 2, that is, in the formation range of the excess length portion $. Thereby, the liquid 6 is prevented from leaking from the left and right sides of the protective film 2. Further, the liquid 6 is prevented from being supplied to the bonding portion, and the dilution of the bonding liquid 3 at the bonding portion is prevented. As a result, a sufficient amount of the adhesive liquid 3 may be supplied to both end portions of the polarizer 丄, and the protective film 2 may be adhered and fixed at the end portion of the polarizer 丨. For the liquid 6 system described above, if the above-mentioned adhesive is dissolved, it is not particularly limited to a specific one, and examples thereof include, for example, methanol and ethanol (et% 〇l). ':propanol (propyiaic〇h〇) l) Alcohols such as acetone, acetone (10) gamma), ketones such as methyl ethyl ketone, benzene 18 f.doc 131 im (benzene), toluene, xylene Or an organic solvent such as aromatic hydrocarbons, methyiene chl〇ride, chloroform or water. Further, in the manufacturing apparatus of the present embodiment, as shown in Fig. 3, a suction nozzle (suction means) 8 is provided for sucking and removing the excess adhesive liquid 3 which does not contribute to the bonding of the polarizer 1 and the protective film 2. Thereby, the optimum amount of the adhesive liquid can be applied without unevenness, and can be supplied to the entire left and right ends of the polarizing photon, and as a result, the in-plane adhesiveness is uneven, and the in-plane uniform polarizing plate can be obtained. . Further, the suction nozzle 8 system is not particularly attracted to the adhesive liquid 3 which is attracted by the liquid 6 by attracting the excess adhesive liquid 3.

In the case of liquid 3, the smooth suction is blocked, and soon the adhesive 3 blocks the suction port 10 . M Here, the suction nozzle 8 is placed so as to be positioned within the range of the excess length portion 9. For the state in which the adhesive liquid 3 is diluted by the liquid 6, a state is added, and the suction port 1G is diluted with the liquid 6 in the end portion of the polarizer i, and at least the bonding at the end 2 It becomes: full. Also, the suction nozzles 2:: 5 are individually configured to provide a structure that can be easily cleaned or overhauled. a early. Therefore, it is preferable that the opening direction of the opening portion of the suction port 10 is appropriate. Such a shape of the opening portion is, for example, flat as shown in the figure, and can be exemplified by an ellipse, a semicircle, a rectangle, a rectangle of the angle ~ FIG. 2, a flat diamond shape, a flat shape, a chamfered shape, and an opening portion. It is suitable to arrange the suction port i to the flat direction and the width of the square 彳 ^^ 19 1311 ^84Pif.d〇c. Thereby, the suction port i is brought close to the bonding portion of the polarizer 1 and the protective film 2, so that the excess adhesive 13 and the liquid 6 are efficiently sucked and removed.

- The person, the photon 1 and the protective film 2 are continuously guided to each other between the pair of drums (adhesive means) 4 in an overlapping state. The photon, the protective film 2, and the Here, the drum 4 is not limited to the structure, and various conventional ones can be used. However, in order to make the appearance of the manufactured polarizing plate 4 a good one, the surface precision is high. Further, the material of the drum 4 is not particularly limited, and examples thereof include metal or rubber, etc. Further, a flat pressing means may be used for the bonding means of the drum 4. Further, the polarizing plate (thin film laminate) 21 of the present embodiment obtained by the above method is formed as shown in Fig. 5, and the protective film 2 is laminated on each of the polarized photo defects (X). The protective film 2 is bonded to the excess length portion 9. The polarizer 1 is produced by treating the hydrophilic polymer with swelling, dyeing, stretching, bridging, etc., for the hydrophilic polymer system. Process moth or dichroic dye The directionality is generally not limited to the one used in the present invention. Specifically, for example, a polyvinyl alcohol-based thin enamel or a partially acetal-formed polyvinyl alcohol system can be exemplified. Film, polyethylene terephthalate film, ehylene-vinyl acetate copolymer film, etc.; octagonalized film, in cellulose ( Ce wrist (10))* Thin film such as thin film = 20 1311574* A polyethylene (p〇lyethylene) oriented film such as a dehydrated material of polyvinyl alcohol or a dechlorination treatment of polyvinyl chloride. When the hydrophilic polymer is extended, it is preferred to set the total stretching ratio in the range of 3 to 7 times, more preferably in the range of 4 to 6 times, and the total stretching ratio is less than 3 times. It is difficult to obtain a polarizing plate with a high degree of polarization. When the polarizing plate is more than 7 times, the film tends to be easily broken. In this hydrophilic polymer system, the total stretching ratio is gradually extended in the whole process of swelling, dyeing, stretching, bridging, and the like. Up to 3 times to The range of 7 times is also acceptable, and it is also possible to extend only in any process, and it is also possible to extend the same process in multiple times. Further, the thickness of the polarizer is not particularly limited, but is generally about 5 to 80 μm. The material for forming the protective film 2 described above is a polymer film which is superior to transparency, mechanical strength, thermal stability, homogeneity, etc., and specifically, for example, polyparaben glycolate (for example) Polyethylene terephthalate) or polypyridyl diacetate (p〇iyethyiene naphthalate) 专 专 ( ( (P〇lyest〇r) 糸 polymer, polystyrene (p〇iyStyrene) or accompaniment - this B a styrene polymer such as acrylonitrile-styrene copolymer (AS resin), a cellulose phthalate polymer of diacetyl cellulose or triacetyl cellulose, Poly sewn; g wind (p〇iysulfone) system, polycarbonate polymer, polyamide polymer, polystyrene (p〇iyimide) polymer, polyolefin ( Polyolefine An acryl polymer such as a compound or a polymethyl methacrylate 21 I if.doc (polymethyl methacrylate). Further, a polyethylene, a polypropylene, a polyolefin having a cyclopentene or a norbornene structure, such as an ethylene-propylene copolymer may be mentioned. An amide polymer such as a polyolefine polymer, a vinyl chloride polymer, a nylon or an aromatic polyamide, or an imido polymerization.飒, if (suifon) φ polymer, polyether sulfone polymer, polyether ether ketone polymer, polyphenylene sulfide polymer, vinyl alcohol (Vinyi aich〇i) 糸 polymer, vinylidene chloride polymer, polyvinyl butyral polymer, arylate polymer, polyoxon (polyoxymethylene) polymer, epoxy polymer, or a blend of the above polymers. Other examples of the acryl-based, urethane-based, acryl-based urethane-based, epoxy-based or silicone-based heat-curing or ultraviolet-curable resins may be mentioned. The polymer film described in Japanese Patent Laid-Open Publication No. 2001-343529 (w0 01/37007), for example, includes a heat having a substitution and/or an imido group in the a-side bond. A resin composition of a plastic resin having a substituted and/or unsubstituted phenyl group and a base {nitrWX thermoplastic resin. Specific examples include an isobutylene (is〇butylene) and an N-methyl maleic anhydride imide 22 • pif. doc (N-methyl maleimide) alternating copolymer and acrylonitrile (acrytonitrile- A thin film of a resin composition of a styrene copolymer can be used as a film composed of a mixed extrusion of a resin composition. These films are small in phase difference, and the relationship between the small photoelastic coefficient can eliminate the unsuitability of the skew unevenness, etc., and the moisture permeability is superior to the humidifying durability. For the protective film 2, the phase difference is as small as possible. Further, in consideration of the viewpoint, the polarizing property, the durability, and the like, it is preferred to use a fibrin-based polyvalent compound. Further, in the cellulose-based polymer, cellulose triacetate is suitable, and a protective film 2 formed of a fine concavo-convex structure including fine particles may be used. Further, the thickness of the protective film 2 is preferably 1 () or less, more preferably 60 or less. For example, in the case of a thin polarizing plate, cellulose acetate (TAC) having a thickness of a degree can be used. In this case, the curric effect of the present invention is more south than that of the conventional polarizing plate (thickness, TAC of 80 terra). The total thickness (thickness of the polarizing plate) is thinner and has no rigidity, and the moisture variation of the polarizing plate is easily affected by the degree of rotation. The moisture permeability of the protective film 2 is preferably in the range of 400 to l_g/rrf 4h. Although the moisture permeability is outside the above range, the effect of suppressing the curl of the present invention is high when a polarizing plate having a relatively high moisture permeability is used. Through the dehumidification system, according to the moisture absorption test of 0208 (cup method), the relative humidity difference of 4〇C, 9〇% is used to make the area J of this sample in the water of 24 small pass steamed (g) number. Further, each of the protective films 2 disposed on both sides of the polarizer 1 can be formed by using each of the 23 I if.doc = the same polymer, and is composed of different polymer seals and the like. 2 The force applied only to the polarizer: for the purpose of bonding, on the other side, also: 2, J (called layer process or reflection prevention treatment, adhesion prevention or diffusion, and even shading - fine) In order to prevent the injured person on the surface of the eccentricity, for example, a hardened skin which is moderately characteristic such as a silicon base, a silicon (four), or the like is formed by attaching a surface of the second twentieth 2 or the like. The reflection of the light outside the surface is prevented for the purpose of the object; the formation of the 臈 is prevented by the reflection of the = 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 : The treatment is on the surface of the polarizing plate to prevent the reflection of light from the polarizing plate by the reflection of external light. For example, the method of squeezing and squeezing (_(10)_) is used to form the surface of the protective surface with the fine concavo-convex structure. For the fine particles contained in the formation of the fine concavo-convex structure, for example, inorganic microparticles which are composed of emulsification, tin oxide, indium oxide, oxidation, oxidation, etc., which are also electrically conductive, or by bridge or The material of the bridging material is the surface of the material (4) transparent micro 24 131153⁄4 pif.doc particles. When the surface fine concavo-convex structure is formed, the amount of fine particles used is the weight of the transparent resin crucible (8) for the surface concavo-convex structure. In general, it is preferable that the degree of the inner portion is 5 to 50 parts by weight. The light-shielding layer may be a diffusion layer that expands the viewing angle and the like, and expands the viewing angle or the like. The layer, the adhesion preventing layer, the hard coat layer, and the diffusion precipitating material may be provided in addition to the protective film 2, or may be separately provided as a separate optical functional layer from the protective film 2. The polarizing plate 21 of the embodiment system 'Applications, etc., can also be used to laminate an optical film (not shown) laminated on the layer of the moon. The Wei layer is __. For example, the polarizing plate ^ θ is bonded to the optical functional layer to make it suitable. For example, =: (including a 1...4 wavelength film, etc.), etc. These films are used in layers or in two layers. For example, in the poor film of the present invention, an optical layer of an elliptically polarizing plate or a circular polarizing plate is used. In the case where the field of view is enlarged, the polarizing plate of the wild corner is used. 4 (4) When the layer is laminated, a wide-viewing type polarizing plate system can be obtained, and in the case of the horizontal well, the person from the viewing side (display side) can be shot to 4 layers. The reflective liquid for the crystal-reflective polarizing plate display and the protective film 2 on the opposite side are attached in a suitable manner by the side of the layer of gold: two::: layer. For example, a reflective layer made of a phase or the like may be provided with a foil or a vapor deposited film of a film made of a reflective metal such as aluminum on one side of a protective film such as a 25'pif.doc treatment. Further, the fine fine concavo-convex structure on the surface of the protective film 2 containing the fine particles is provided with a metal reflective layer or the like in a suitable manner such as a vapor deposition method or a plating method. The reflective layer of the fine concavo-convex structure described above diffuses incident light by diffuse reflection to prevent reflection or diffuse reflection, and has the advantage of suppressing unevenness of light and dark. Further, the protective film 2 system containing fine particles is also diffused by the incident light and its reflected light when they are transmitted.

In order to further suppress the advantages of uneven brightness and the like. The formation of the reflective layer of the fine concavo-convex structure, which reflects the fine concavo-convex structure of the surface of the protective film 2, may be, for example, a vapor deposition method, an ion plating method, a sputtering method, or the like. A method of directly attaching a metal to the surface of the film 2 or the like in a suitable manner such as a plating method or the like is carried out.

Further, a reflective polarizing plate may be used instead of the protective film 2 formed directly on the polarizing plate 21, and a reflective sheet composed of a protective layer 2 and a reflective layer 2 may be used. Further, in the case where the reflective layer is formed of a metal and the reflective surface is covered by the protective film 2 or the polarizing plate, the decrease in reflectance due to oxidation can be prevented. Further, the initial reflectance is continued for a long period of time, and the film 2 can be avoided when the film is protected by another pure layer. The f-transmissive polarizing plate is obtained by a layer in which the light is reversed by the reflective layer and is made into a translucent mirror (five). The semi-transmissive polarizing plate is provided at t曰. The side of the show 曰 f. The case where the + transmission of the semi-transmissive polarizing plate is used in a bright environment, 26 131153⁄4 pif.doc f is incident on the side (display side) The external light is used for the display light, and the environment is used to make the (4) occasions use the _ (baeki_ first). Therefore, it is possible to reduce the power consumption. For the polarizer 21', you will have more layers. TM η page "Elliptical partial plate formed by the difference of the target position or zero-neutral pure feed. The threat wrinkle U makes the phase difference thin on the polarizing plate 21 to accumulate via the adhesive layer.

The method of forming a new adhesive layer on the surface on which the protective film 2 is peeled off is laminated or the method of not peeling off the protective film 2, or by laminating the laminate. When the linearly polarized light is changed to an ellipse or a polarized light, and the _polarized or circularly polarized light is changed to the money polarized light, or the polarized light method of the linear polarized light is changed, the phase difference of $ is used. In particular, a phase difference film system in which linearly polarized light is circularly polarized and circularly polarized light is linearly polarized is used, and a so-called ν is used to change the polarization direction of the linearly polarized light.

The elliptically polarizing plate system, for example, compensates (prevents) the coloring (blue or yellow) generated by the birefringence of the liquid crystal f of the liquid crystal display device of the super twisted nematic (STN: Super Pwisted Nematic) mode, and is effectively used in the fascination. The occasion of black and white display of coloring. Further, by controlling the three-dimensional refractive index system, it is also possible to compensate (prevent) the relationship of the coloration which occurs when the pupil plane of the liquid crystal display device is observed from an oblique direction. The circularly polarizing plate system, for example, is effective for use in an image of a reflective liquid crystal display device to be displayed, and has a function of preventing reflection. The specific sequence of the above-mentioned phase difference film 24 is exemplified by poly 5 carbon acid g (p〇IyCarb〇nate), 27 ipif.doc polyvinyl alcohol (polyrinylalchol), polystyrene (p〇lystyrene), polyfluorene A film composed of a suitable polydazole of polymethyl methaciylate, polypropylene or other polyolefin, polyarylate, polyamide, or the like The resulting birefringent film or the like is extended. The retardation film system, for example, may have a suitable phase difference by the birefringence of various wavelength films or liquid crystal layers for the purpose of coloring or viewing, etc., or two or more retardation films may be laminated to control Optical characteristics such as phase difference. Further, in the above-described elliptically polarizing plate or reflective elliptically polarizing plate, a polarizing plate, a reflective polarizing plate and a retardation film are laminated in an appropriate combination. The elliptically polarizing plate or the like can be formed into a single layer of a liquid crystal display device by a combination of a (reflective) polarizing plate and a retardation film, and reduced to an elliptical shape as described above. The film is superior to the manufacturing efficiency of the stability of the quality or the build-up of the proprietary k-liquid liquid daily display device. "The polarizing plate system that makes the bias and brightness (4) ship is set in the liquid: the day and the early day of the "the side plus the money. After the brightness is thinned, etc., after the light or the reflection from the back, etc. (4) When the light is incident, the first axis Linear polarized light or circularly polarized light in a given direction is reflected, and the characteristics of the pot are added. The brightness-enhancing film is laminated on the polarizing plate, and the light is emitted from the backlight, and the light is transmitted to obtain the transmitted light. Light other than the above-mentioned predetermined silk state 28 131153⁄4 if.doc ==:: after =:= Raise the brightness of the film surface to enhance the brightness of the film 'to make it - part or all of the light increase of the film ==== === At the same time: to increase the amount of light available to increase the size of the shirt, the image of the day is not rising, to the German and Japanese ~ 使 ~ make the child soar without using brightness enhancement: from the f-face of the doped liquid crystal unit through the polarizer

And the photon 1 ΞίΓΤΐ photon 1 characteristic 'about 5G% of the light is recorded by the first sub-1, from its weight, the liquid crystal image can be used to reduce the light. The brightness is raised (10), and the light person absorbed by the slanted shirt is exposed to the polarizer i, and the brightness is increased by H1, and the reflection material placed on the back side is reversed and then incident on the pure lift _, brightness (4) The film system only makes the polarization direction of the reflected and inverted light between the two become polarized by the polarizer.

The polarized light is transmitted to the polarizer. Thereby, the light such as the backlight can be efficiently displayed on the image of the liquid crystal display device, so that the display is not visible. The upper brightness is raised, and between the film and the above-mentioned reflective material, a diffusion plate can be provided. The light in the polarized state reflected by the twist-lifting film is applied to the reflective layer or the like, and the diffusing plate is provided so that the passing light is uniformly diffused while releasing the polarized wire S to form a polarized light (four). ^Diffuse plate system restores the original natural light cancer to the polarized light. This non-polarized state, that is, the natural light bear 29 I3115Mp, doc light reflection layer, etc., is reflected by the reflective layer, and then repeatedly passed through the diffusion plate. Shell-lifting film. Thus, by providing a diffusing plate in which the biasing level is restored to the natural light state of the filament between the brightness-enhancing film and the reflective layer or the like, it is possible to maintain the brightness of the display surface while maintaining the display surface unevenness. , both - bright face. By providing the diffusing plate, the first person's illuminating light just increases the number of repetitions of the reflection, and combined with the diffusing function of the diffusing plate, it becomes a uniform-bright display surface. * The thin film system for the elimination of the deadness can be suitably used, for example, a multilayered layer of a dielectric multilayer, a film or a film having different refractive index anisotropy, and a direct light system showing the polarization axis of the household is transmitted through other light systems. The reflection of the special 5, such as a film of cholesteric liquid crystal polymer or its oriented liquid crystal layer supported on the film substrate, showing any circular polarization of the left-handed Ϊ to reflect other light Transmitted

The ancient θ ^ makes the linear polarization of the fixed partial light to be transmitted type. By making the transmitted light as it is, the polarizing axis is made - and the absorption loss by the polarizing plate 21 is suppressed by the light. - Aspects such as the biliary (four) liquid crystal layer makes the circle biased. In the case of competition for the day and the degree of improvement of the film system, it can also be incident on the occasion where the phase is caused by the phase #^ * suppression, and the circular polarization is i, and for a wide linear polarization, The polarizing plate 21 is preferably used. When the light is converted by Qian Weiwei, by making the /4 wavelength plate, the wide wavelength of the circle in the visible light field can be used as the phase difference film, for example, for the wavelength. The difference between the layer and the other phase difference characteristic wavelength film

When A and 'Cholesterol liquid crystal layer' are overlapped and arranged in a combination of two different reflection wavelengths, and two or more layers of Ix, it is possible to obtain a wide-range wavelength range such as not to be polarized. Reflected. The junction 'is achieved transmission circular polarization over a wide wavelength range. The polarizing plate 21 is a polarization separation type polarizing plate as described above, and is composed of a polarizing layer or two or more optical functional layers. Therefore, the reflective polarizing plate or the semi-transmissive polarizing plate and the phase may be used.
