Abstract: A display device includes a substrate, a first conductive layer disposed on the substrate, a second conductive layer disposed on the first conductive layer and a third conductive layer disposed on the second conductive layer. The first conductive layer includes a data line extending in a first direction. The second conductive layer includes a first scan line extending in a second direction intersecting the first direction, and a second scan line spaced apart from the first scan line and extending in the second direction. The third conductive layer includes a first driving voltage line extending in the second direction, a first common voltage line spaced apart from the first driving voltage line and extending in the second direction, and a pixel electrode disposed between the first driving voltage line and the first common voltage line in a plan view.

Abstract: A gate driver includes stages. Each stage includes: a first output part for outputting a carry signal in response to a voltage of a first node; a first input part for controlling the voltage of the first node in response to a previous carry signal; a second input part for controlling the voltage of the first node in response to a first next carry signal; a second output part for outputting a scan signal in response to the voltage of the first node; a third output part for outputting a sensing signal in response to the voltage of the first node; and a scan signal control part for applying a first low power voltage to an output terminal of the second output part to which the scan signal is output in response to a second next carry signal of which a pulse is generated before the first next carry signal.
