Elliptically Polarizing Plate, Optical Film and Image Display
摘要:
An elliptical polarization plate includes: a scatter/two-color absorption composite type polarizer formed by a film of such a structure that minute areas are scattered in a matrix formed by a translucent resin containing iodine-based light absorber; a transparent support body; and discotic liquid crystal or nematic liquid crystal having an optically anisotropic layer where the optical axis of the liquid crystal molecule is inclined from the transparent support body surface. The elliptical polarization plate has a wide field of view, a high contrast, a high transparency, and a high polarization degree while suppressing the irregularities of the transparency when performing black display.
