Provided are a gate driver and a display device including the same. The display device may include a display panel configured to display an image, a data driver configured to supply a data voltage to the display panel, a gate driver including a scan signal generation circuit configured to supply a scan signal to the display panel and a light-emitting signal generation circuit configured to supply a light-emitting signal to the display panel, and a clear signal line connected to the gate driver to deliver a clear signal in an alternating current form including a positive voltage and a negative voltage, wherein the gate driver initializes at least one of nodes of the scan signal generation circuit and nodes of the light-emitting signal generation circuit based on the clear signal.

Gate driving circuit and display device including the same

A gate driving circuit and a display device including the same are discussed. A signal transmitter of the gate driving circuit can include a first charge controller configured to charge a first control node in response to a voltage of a VST node, a second charge controller configured to charge a second control node using a first transistor that is turned on in response to an (N+1)th clock generated following an Nth clock, a first discharge controller configured to discharge the first control node in a charging period of the second control node, and a second discharge controller configured to discharge the second control node when the voltage of the VST node is a high voltage or in a charging period of the first control node.
