Abstract: Provided is a gate driving circuit comprising an N-th stage and an N+1-th stage. The N-th stage outputs an N-th scan gate signal based on an N-th scan clock signal, a voltage of a QN node, and a voltage of a QBN node and to output an N-th carry signal based on an N-th carry clock signal, the voltage of the QN node, and the voltage of the QBN node. The N+1-th stage outputs an N+1-th scan gate signal based on an N+1-th scan clock signal, a voltage of a QN+1 node, and the voltage of the QBN node and an N+1-th carry signal based on an N+1-th carry clock signal, the voltage of the QN+1 node, and the voltage of the QBN node. The N-th stage and the N+1-th stage share an inverting circuit. The inverting circuit controls the QBN node based on a third signal. N is a positive integer.

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.
