Wide viewing angle liquid crystal display having both optical compensator and optical diffuser |
摘要 |
A liquid crystal display unit produces image carrying light through a liquid crystal layer having a positive anisotropy of refractive index; an optically compensating layer with a negative anisotropy of refractive index is provided on an optical path of the image carrying light so as to compensate the optical anisotropy of the liquid crystal, and the image carrying light is incident onto an optically diffusing layer after the optical compensation so as to widen the viewing angle of the liquid crystal display unit without deterioration of image contrast.
