Abstract

See full text

Disclosed is a driving circuit of a liquid crystal display having a stable operation characteristic. The driving circuit comprises first and second transistors connected in series with each other between an output terminal of an (N-1).sup.th circuit and a Vss terminal, a third transistor operated by a clock signal and having a drain for receiving an inversion signal of the clock signal and a source connected to an N.sup.th gate line, a fourth transistor having a drain connected to the source of the third transistor and a source connected to the Vss terminal, fifth and sixth transistors connected in series with each other between a VDD terminal and the Vss terminal, a seventh transistor operated by an output signal of an (N+1).sup.th circuit, an eighth transistor operated by an output signal of an (N+1).sup.th circuit, a first capacitor formed at a front terminal of a gate of the third transistor, and a second capacitor formed between a gate and a drain of the sixth transistor.
