Gate driving circuit and display device including the same
Last updated:
Abstract:
A gate driving circuit includes a plurality of stages connected to one another, wherein each of the plurality of stages includes an output unit which outputs a first clock signal as a gate voltage in accordance with a voltage of a Q node and a voltage of a QB node; a first node control unit which controls the voltage of the Q node; and a second node control unit which controls the QB node, wherein the first node control unit includes second and third transistors which discharge the Q node, the second transistor outputs a ground voltage to the Q node in response to a second clock signal, and the third transistor outputs the ground voltage to the Q node in response to the voltage of the QB node.
