ABSTRACT:
A projection type liquid crystal display apparatus comprises three light valves showing a same temperature level to eliminate color distortions at low cost without requiring a large space. Rays of light of R, G, and B from a light source are made to enter light valves of R, G and B respectively by way of reflector mirrors and field lenses for R, G and B and modulated by the light valves before they are combined to produce an image, which image is then projected onto a screen by means of a projection lens group. The liquid crystal light valves are connected with each other by way of a high thermal conductivity sheet member, which is held in contact with the rear surface of each of the liquid crystal light valves.
