摘要：
A liquid crystal light valve includes a first substrate having a transparent electrode formed thereon, a second substrate, a liquid crystal provided between the first and second substrates, a photoconductive layer formed between the liquid crystal layer and the first substrate, the photoconductive layer being adapted to change impedance thereof in response to an incident ray of light thereto, and a light waveguide for emitting light from the first substrate side to the photoconductive layer.
