ABSTRACT:
An optical scan type display device is provided to have an excellent display characteristic so that it may achieve a large-screen and high-resolution display. The display device is arranged to have a pair of glass substrates and a liquid crystal material sealed therebetween. On one of the glass substrates, there are formed a plurality of optical waveguides, a plurality of signal wires ranged vertically to the optical waveguides, a plurality of pixel electrodes located on sections defined by the optical waveguides and signal wires, and a plurality of light switching elements located at the crossing spots between the optical waveguides and the signal wires. The pixel electrodes are selectively driven in response to the light signal applied through the signal wires and the light switching elements. The optical waveguides are formed of optical fibers and the surface of the substrate is mirror-finished.
