Abstract: A first thin film is formed on one surface of an insulating base, and a second thin film having a thermal conductivity higher than the first thin film is formed on the first thin film. An amorphous semiconductor thin film having a higher thermal conductivity than the second thin film is formed on at least the second thin film. The amorphous semiconductor thin film is changed to a polycrystalline semiconductor thin film through laser annealing. The provision of the second thin film results in larger and uniform crystal grain diameters and less proturberances in the polycrystalline semiconductor thin film.

This enables a plurality of observers to simultaneously obtain a stereoscopic view using a binocular parallax without wearing special glasses and without having to position themselves in a very limited number of positions relative to the screen. Vertical diffusion can also be provided by using a lens sheet. The screen can be made concave in the horizontal or vertical directions, or both.

Abstract: To provide a display device capable of displaying a moving picture with high definition and at high speed. An image display system includes: an image display unit; and a control unit. The control unit has: a block discrimination circuit portion; an image processing portion; a storage portion; and a synchronizing signal generation portion. The block discrimination circuit portion discriminates a moving picture or a still picture to process the image information in accordance with the discriminated result, in which the number of gradations for the image information processed when the discriminated result is the moving picture is lower than when the discriminated result is the still picture. Thereby, the high definition image display and the high speed moving picture display can be effected by reducing the information with lower degree of recognition.
