ABSTRACT:
A liquid crystal projector includes a light source, a color filter for adding color projection image, a liquid crystal panel for forming a projection image on it, a projection lens and an optical unit located between the color filter and the liquid crystal panel for optically coupling the color filter and the liquid crystal panel. The color filter is separately located from the liquid crystal, and therefore the increase in temperature on the color filter because of absorbing the light from the light source has less effect on the liquid crystal panel.
