Abstract:
A gate driving circuit includes stages connected in series. In a stage, a pull-up part pulls up a present gate signal to a level of a first clock signal, and a pull-down part receives a next gate signal from a next stage to discharge the present gate signal to an off-voltage. A pull-up driving part turns on or turns off the pull-up part and the carry part. A holding part holds the present gate signal at the off-voltage and a present inverter turns on or turns off the holding part in response to the first clock signal. A ripple preventing capacitor is connected between a present node and an output terminal of a previous stage's inverter to prevent a ripple at the present Q-node in response to an output signal from the previous inverter.
