Abstract:
A gate driving circuit is provided which includes a plurality of stages cascade-connected with each other and outputting a plurality of gate signals. An n-th (n is a natural number) stage includes a gate output part, a first node control part and a carry part. The gate output part includes a first transistor. The first transistor outputs a high voltage of a clock signal to a high voltage of an n-th gate signal in response to a high voltage of a control node. The first node control part is connected to the control node to control a signal of the control node and includes at least one transistor having a channel longer than the channel length of the first transistor. The carry part outputs the high voltage of the clock signal to an n-th carry signal in response to the signal of the control node.
