摘要：
The invention provides a semi-conductor light valve device and a process for fabricating the same. The device comprises a composite substrate having a supporte substrate, a light-shielding thin film formed on said supporte substrate and semiconductive thin film disposed on the light-shielding thin film with interposing an insulating thin film. A switching element made of a transistor and a transparent electrode for driving light valve are formed on the semiconductive thin film, and the switching element and the transparent electrode are connected electrically with each other. The transistor includes a channel region in the semiconductive thin film and a main gate electrode for controlling the conduction in the channel region, and the light-shielding thin film layer is so formed as to cover the channel region on the side opposite to said channel region, so as to prevent effectively a back channel and shut off the incident light.
