Liquid crystal display device

摘要

To propose a liquid crystal display device for suppressing a wavelength dependence and a viewing dependence in a dark state. A polarizer ( 21 a) of a circularly polarizer ( 21 ) and a polarizer ( 22 a) of a circularly polarizer ( 22 ) are arranged such that an absorption axis (90°) of the polarizer ( 21 a) and an absorption axis (0°) of the polarizer ( 22 a) are at substantially right angle to each other. A retardation plate ( 21 b) of a circularly polarizer ( 21 ) and a retardation plate ( 22 b) of a circularly polarizer ( 22 ) are arranged such that a slow axis (165°) of the retardation plate ( 21 b) and a slow axis (75°) of the retardation plate ( 22 b) are at substantially right angle to each other. A retardation plate ( 21 c) of a circularly polarizer ( 21 ) and a retardation plate ( 22 c) of a circularly polarizer ( 22 ) are arranged such that a slow axis (105°) of the retardation plate ( 21 c) and a slow axis (15°) of the retardation plate ( 22 c) are at substantially right angle to each other.
