Abstract:
Gate drive circuit includes a plurality of stages connected one after another to each other. An m-th stage includes a pull-up section outputting a first clock signal as a gate signal of the m-th stage to an output terminal, a pull-down section applying a low voltage to the output terminal, a carry section outputting the first clock signal as a carry signal of the m-th stage in response to the high voltage of the first node signal, a first carry holding section maintaining the carry signal of the m-th stage at the low voltage in response to the high voltage of the first clock signal and a second carry holding section maintaining the carry signal of the m-th stage at the low voltage in response to a high voltage of the second clock signal.
