摘要： Provided is a continuous web of polarizing film for an organic EL display device which has a thickness of 10 μm or less and exhibits high optical characteristics. The polarizing film for an organic EL display device is made of a polyvinyl alcohol type resin having a molecularly oriented dichroic material, and formed through stretching to have a thickness of 10 μm or less and exhibit optical characteristics satisfying the following conditions: T≧42.5; and P≧99.5, wherein T is a single layer transmittance, and P is a polarization rate. The polarizing film for an organic EL display device may be prepared by subjecting a laminate comprising a non-crystallizable ester type thermoplastic resin substrate and the polyvinyl alcohol type resin layer formed on the substrate, to 2-stage stretching consisting of preliminary in-air stretching and in-boric-acid-solution stretching.

摘要： A light diffusion film (20) having small back scattering can be obtained by using fibers having two kinds of birefringent regions (21A) and (21B). An outer portion of fiber (21) is a first birefringent region 21A and an inner portion of fiber (21) is a second birefringent region (21B). While the first birefringent region (21A) is in contact with a transparent resin (22), the second birefringent region (21B) is not in contact with the transparent resin (22). When a refractive index (n1) in major axis direction of the first birefringent region (21A) is a value between a refractive index n2 in major axis direction of the second birefringent region (21B) and a refractive index n0 of the transparent resin (22), interface reflection between the transparent resin (22) and the fiber (21) can be reduced, which leads to obtain a light diffusion film (20) having small back scattering.

摘要： A light pipe is obtained by laminating on one or both surfaces of a light-transmitting resin plate a polarized-light scattering plate having fine birefringent domains dispersed therein and hence showing anisotropy in scattering. The polarized-light scattering plate comprises a transparent film having fine domains dispersed therein comprising a liquid crystal polymer which exhibits nematic at temperatures lower than the glass transition temperature of the polymer constituting matrix of the transparent film and has a glass transition temperature of 50° C. or higher. The light pipe as a laminate may further comprise a specular reflection layer, a polarization-retaining lens and a light diffusion layer laminated thereon. The light pipe may further comprise a light source mounted at least on one side face thereof to provide a planar polarized-light source.

摘要： A polarization component, capable of efficiently reflecting an obliquely transmitted light beam toward a light source without degrading the transmission-polarization property of a perpendicular incident light beam, is provided. A C-plate having an oblique retardation of at least λ/8 with respect to a light beam inclined by at least 30° is disposed between at least two reflective circular polarizer layers whose selective reflection wavelength bands of polarized light overlapping each other. A combination of a reflective linear polarizer and a quarter wavelength plate may be used instead of the reflective circular polarizer. Alternatively, a combination of two reflective linear polarizer layers and two quarter wavelength plate layers (Nz≧2) disposed therebetween can provide a similar effect. Further, a combination of two reflective linear polarizer layers and a half wavelength plate (Nz≧1.5) disposed therebetween may be used.

摘要： A method is provided by which a highly functional thin retardation plate with no appearance defect can be produced. First, as shown in FIG. 1A, a solution of a liquid crystalline compound is applied on a transparent base 1 and dried, or alternatively, a liquid crystalline compound on the melt is applied on the transparent base 1, and thus a liquid crystalline compound-containing layer 2a is formed. Then, as shown in FIG. 1B, the liquid crystalline compound-containing layer 2a is brought to a liquid crystal state or a liquid state so as to form a layer 2b. An alignment substrate 3 is brought into contact with an upper portion of the layer 2a so that the liquid crystal compound is aligned in a particular direction. Then, after the liquid crystalline compound is aligned in the particular direction, as shown in FIG. 1C, the liquid crystalline compound-containing layer 2b on the melt is solidified, and the alignment substrate 3 is removed. Thus, a retardation plate 4 composed of the transparent base 1 and an optically anisotropic layer 2c is produced.
