Abstract: A display device includes a substrate having an active area, a visible region located on the active area, and a non-visible region farther from the active area in a first direction than the visible region is; a first conductive layer disposed on the substrate; a first insulating layer disposed on the first conductive layer; a second conductive layer disposed on the first insulating layer; a first via layer disposed on the second conductive layer; a second insulating layer disposed on the first via layer; and a third conductive layer disposed on the second insulating layer and including touch signal lines. The visible region includes a line area where the second conductive layer is disposed, and a line-free area where the second conductive layer is not disposed. The third conductive layer includes a dummy pattern disposed in the line-free area and has a width greater than the touch signal lines.
