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. When reflective linear polarizer layers are used, they must be bonded together with their axial directions set at a certain angle. The polarization component is preferably used in various image display apparatuses such as liquid crystal display apparatuses and organic EL display apparatuses.

摘要： An optical element having a plate-like shape includes a light-transmitting resin and minute regions. The minute regions are dispersedly distributed in the light-transmitting resin and have a birefringence different from the light-transmitting resin. At least one of the light-transmitting resin and the minute regions contains at least one luminescent material. The thus arranged optical element omits the necessity to separately provide a light emitting means made of a light-transmitting resin containing reflective dots or the like as in a conventional manner, while being capable of allowing light, which results from excitation by incident light in the optical element (through the luminescent material), to be emitted to the outside in the form of linearly polarized light having a certain plane of vibration.

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： The present invention provides an anisotropic light scattering element that is further improved in controlling of the viewing angle and also reduced in the thickness. The anisotropic light scattering element has an anisotropy in the scattering intensity, and includes an anisotropic light scattering layer having an anisotropy in the light scattering intensity depending on the polarization direction of incident linearly polarized light, and a birefringent layer having a phase difference of less than 1/10 wavelength with respect to incident light in a normal direction and a phase difference with respect to incident light in a direction inclined from the normal that is different from the phase difference with respect to incident light in a normal direction. The birefringent layer develops a phase difference with respect to incident light in a direction inclined from the normal.
