Abstract:
A gate driving circuit including a plurality of stage circuits to output a plurality of gate signals, a N-th stage circuit of the plurality of stage circuits includes: an output pull-up part including a control electrode connected to a first node, the first node being configured to have a potential increase in response to a (N−1)-th control signal received from a previous stage circuit of the N-th stage circuit, the output pull-up part to receive a clock signal to output a gate signal of the N-th stage circuit; a control node pull-up part to control the potential of the first node by using the (N−1)-th control signal; and a control node pull-down part to discharge the first node to a second low voltage according to a (N+1)-th control signal, wherein the output pull-up part is to discharge the gate signal of the N-th stage circuit in a (N+2)-th stage circuit.
