摘要： A light valve has a composite substrate comprised of an electrically insulating substrate and a semiconductor single crystal thin film formed over the electrically insulating substrate. A pixel array comprising semiconductor switch elements is formed in the semiconductor single crystal thin film. A peripheral circuit having circuit elements is formed in the semiconductor single crystal thin film so that a small-sized, high speed light valve is obtained. X- driver and Y-driver circuits are formed in the semiconductor single crystal thin film and controlled by a control circuit, such as a video signal processing circuit, which receives and processes video signals inputted directly from an external source. The peripheral circuit can be a DRAM sense amplifier for sensing charges stored in each pixel of the pixel array to detect defects in the pixel array. The peripheral circuit can be a photosensor circuit for detecting an intensity of incident light to monitor the performance of a light source of the light valve. The peripheral circuit can be a temperature sensor for detecting the temperature of a liquid crystal layer of the light valve, and may be comprised of Darlington connected NPN transistors formed in the semiconductor single crystal thin film. The peripheral circuit can also be a solar cell for converting incident light into electrical energy to supply power to at least one of the pixel array, X-driver and Y-driver circuits and the peripheral circuit.

A first alignment layer is disposed in contact with the liquid crystal layer and has a uniaxial alignment characteristic effective to align the molecular axes of liquid crystal molecules immediately adjacent to the first alignment layer in a predetermined direction parallel to the liquid crystal layer. A second adjacent layer is opposed to the first alignment layer in contact with the liquid crystal layer. The second alignment layer has a random homogeneous alignment characteristic and a water repellency characteristic defined in terms of a water contact angle of more than 70.degree. jointly effective to align the molecular axes of liquid crystal molecules immediately adjacent to the second alignment layer in either of two orientation directions oppositely inclined relative to the predetermined direction in parallel to the liquid crystal layer.
