LCD having a polarization or diffusion plate with an irregularly coated first opaque material and a black matrix of a second opaque material

摘要

A liquid crystal display with an improved viewing angle is disclosed which prevents gray scale inversion within a range of 60 DEG in every direction because the change of a gray level according to the viewing angle is small. Light transmitted through the liquid crystal is scattered by a diffusion plate so that the brightness in front can be improved instead of narrowing the viewing angle, or uniform screen quality can be obtained by widening the viewing angle. The diffusion coefficient of the diffusion plate can be easily controlled. Further, it is possible to prevent a decrease in contrast due to external ambient light by screen-printing a black matrix pattern or atomizing a black dye on the diffusion plate.
