Abstract
A process for forming a light valve device comprises forming a semiconductor single crystal film to form a composite substrate by polishing a semiconductor single crystal substrate after an electric insulating substrate has been bonded thereto; forming a group of pixel electrodes for defining a pixel region and a group of switch elements for selectively energizing the pixel electrodes by integrating a pixel array portion over the composite substrate; forming a liquid crystal aligning means for the pixel region; superposing an opposed substrate over the composite substrate with a gap therebetween; and filling the gap with liquid crystal material.
