ABSTRACT:
A liquid crystal display device comprises a light source, a diffusion plate for diffusing light beams emitted from the light source, and a liquid crystal panel for forming an image thereon as a result of a variation in scattering efficiency wherein the diffusion plate and liquid crystal panel are separately arranged with a distance between them, thereby the liquid crystal panel being illuminated by the diffused light beams uniformly, and a liquid crystal projection display device further comprises a color separator, a light deflector, a projector lens assembly and apertures having a shape similar to an image of the light source formed near the pupil of the projector lens assembly.
