Abstract:
A liquid crystal display device comprising:a light source; an optically transmissive substrate positioned to receive light from the light source; a light valve matrix secured to the substrate and comprising an array of transistors formed from a thin film of single crystal material, an array of electrodes, each electrode being electrically connected to a transistor, a gate positioned between a channel region of each transistor and the optically transmissive substrate, a liquid crystal material through which light from the light source is selectively transmitted, and an of insulator positioned between the gate of each transistor and the channel region of said transistor; a driver circuit electrically connected to the light valve matrix for actuating the light valves; and an optical system that couples light transmitted through the light valves onto a viewing surface.
