Abstract
A solid-state optical device with a plurality of cells having a plurality of optical functions is disclosed. Each of the cells comprises a transparent substrate, an anti-reflection film formed on the lower surface of the transparent substrate, a MOS transistor and a capacitor formed on the upper surface of the transparent substrate, a liquid crystal display device formed on the MOS transistor and capacitor, and window for leading a light signal incident on the liquid crystal display device from above to the transparent substrate. At least either a channel region of the MOS transistor and a region intervening between pair electrodes of the capacitor is formed of a photoconductive film. A transparent medium intervenes between the transparent substrate and photoconductive film such that light signal led through the window to the transparent substrate is reflected by an object disposed in contact with anti-reflection film to reach the photoconductive film, thereby generating carriers therein.
