<p>An optical valve device in which an integrated circuit substrate comprising a semiconductor thin film and driving circuits and switching elements both formed on the semiconductor thin film and electro-optical materials are incorporated as one body. The integrated circuits for driving a display, driving electrodes, picture element electrodes and active elements including switching elements are formed on the substrate finely and densely. The semiconductor single crystal thin film having lattice defects of low density is formed on an electrically insulating support layer and the active elements are formed thereon by using microelectronics techniques. Light transmission of the electro-optical material layer is controlled by the active elements. The optical valve device is suitable to a high resolution video projector of a small size and a color displaying device of a matrix type.</p> |
