摘要：
A reflection type liquid crystal light valve comprises a first transparent substrate, a second transparent substrate for supporting the liquid crystal layer together with the first transparent substrate therebetween, a driver for driving liquid crystal molecules of the liquid crystal layer to modulate a light directed to the liquid crystal layer through the first transparent substrate, and a heat sink substrate attached to the second transparent substrate and having a reflection plane for reflecting the light directed thereto through the second transparent substrate to the first transparent substrate, on a plane thereof facing the second transparent substrate.
