Zusammenfassung:A gate driving circuit comprising stages cascade-connected with each other and configured to output gate signals, a stage of the stages including a pull-up circuit configured to output a high voltage of a clock signal as a high voltage of a gate signal in response to a bootstrap voltage of a control node in a period of a frame period, a first discharging circuit configured to discharge a voltage of the control node to a first low voltage in response to a carry signal of at least one stage of the plurality of stages that is subsequent to the stage, and a second discharging circuit configured to discharge a voltage of the control node to a second low voltage being lower than the first low voltage in response to a carry signal of at least one stage of the plurality of stages that is subsequent to the stage.
