Liquid crystal light valve using non-monochromatic writing light |
摘要 |
A liquid crystal display unit uses a photoconductive type liquid crystal light valve. By using non-monochromatic light as the writing light, the light excitation can be induced near the surface layer of the photoconductive layer by light of a shorter wavelength and also on portions deep in the layer by light of a longer wavelength. Thus, it is possible to induce the light excitation effectively on the photoconductive layer even when it is thick.
