Abstract
An LCD gate line drive circuit is constituted by plural stages of TFT-LCD drive circuits which are each composed of a shift register, a set/reset flip-flop and a buffer section and which are successively driven repeatedly. A set input terminal in each stage of drive circuit is connected to an output terminal of the preceding stage of drive circuit, while a reset input terminal in each stage of drive circuit is connected to an output terminal of the succeeding stage of drive circuit, and an operating bias current in the buffer section of the stage concerned is turned ON only during the period from the start of drive in the preceding stage until the start of drive in the succeeding stage.
