Abstract
A circuit adapted to dynamically activate an electro-optical display device is constructed from a thin-film gate-insulated semiconductor device. This device comprises PMOS TFTs producing only a small amount of leakage current. Besides the dynamic circuit, a CMOS circuit comprising both NMOS and PMOS thin-film transistors is constructed to drive the dynamic circuit.
