Abstract
A gate driving circuit includes a first driving stage driving a first gate line included in a display panel. The first driving stage includes a first output transistor outputting a first carry signal on the basis of a first clock signal in response to a voltage of a first node, a second output transistor outputting a first gate signal on the basis of the first clock signal in response to the voltage of the first node, a first control transistor applying a second clock signal to a second node, a second control transistor applying a start signal to the first node in response to a voltage of the second node, and a third control transistor applying a first discharge voltage to the first node in response to the first carry signal.
