Abstract

The liquid crystal project includes a light source, color separation mirrors, liquid crystal panels, color combining mirrors and a projection lens; the color combining mirror located near the projection lens is formed in the form of a transparent block having a color combining film held between two prism; a polarizer and a lambda/4 plate are arranged between the liquid crystal panels and a projection lens to militate stray light.
