ABSTRACT:
A liquid crystal display device of optical writing type has a first transparent substrate, a first transparent electrode formed on the first transparent substrate, and a photoconductive layer formed on the first transparent electrode and including hydrogenated amorphous silicon carbide (a-Si.sub.1-x C.sub.x :H). The display device also has a second transparent substrate, a second transparent electrode formed on the second transparent substrate, and a liquid crystal layer disposed between the photoconductive layer and the second transparent electrode. The dielectric mirror can be made of alternating layers of hydrogenated amorphous silicon carbide (a-SiC:H) with different silicon to carbon ratios.
