Abstract:
1. A projection type liquid crystal display device comprising: a plurality of liquid crystal display panels provided correspondingly to a plurality of colored lights and modulating the plurality of colored lights based on video data, each one of the plurality of liquid crystal display panels having a disclination pattern at a part of an on-pixel adjacent to an off-pixel, said disclination pattern comprising disclination lines extending along boundaries between the on-pixel and the off-pixel; a light synthesizing unit for synthesizing the colored light modulated by the liquid crystal display panels, respectively, into one image; and a projecting unit for projecting the synthetic light produced by the light synthesizing unit onto a screen, wherein, the alignment direction of one of the plurality of the liquid crystal display panels which provides an image inverted in relation to images provided by the other liquid crystal display panels is arranged to form a substantially 90 degree angle with the alignment directions of the other liquid crystal display panels, so that said respective disclination lines of said disclination pattern corresponding to said on-pixel of each one of the plurality of the liquid crystal display panels substantially coincide with each other in an image displayed on the screen.
