Abstract:
1. A liquid crystal projector including a liquid crystal display, said liquid crystal display having a liquid crystal cell in which a liquid crystal is sealed between a pair of transparent substrates, and an incident-side polarizer and an exit-side polarizer respectively disposed in front of and at the back of said liquid crystal cell, said liquid crystal projector comprising: a polarization azimuth compensator, disposed between said incident-side polarizer and said liquid crystal cell and/or between said exit-side polarizer and said liquid crystal cell, for compensating an azimuth of a polarization plane; a TFT circuit pattern formed on one of said pair of transparent substrates; and a black matrix formed on the other one of said pair of transparent substrates, wherein said TFT circuit pattern and said black matrix have periodic microstructures arranged with a pitch allowing diffraction of visible light.
