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.
