ABSTRACT:
A projection type liquid crystal display device includes a light source and condenser lenses for emitting two beams of light which are orthogonal to each other. One of the light beams passes through a liquid crystal panel of one color, and the other light beam is further divided into two light beams each of which passes through liquid crystal panels of other colors. The three light beams are then synthesized by dichroic mirrors and fed to a projection lens system.
