    Abstract: A display device includes a display substrate, a first connection wiring, and a signal wiring. The display substrate includes a display area and a pad area disposed outside the display area. The first connection wiring is disposed on the pad area of the display substrate. The signal wiring is disposed on the first connection wiring of the pad area of the display substrate. The signal wiring is electrically connected to the first connection wiring through a first contact hole. The signal wiring includes at least one first opening at least partially surrounded by the signal wiring in a plan view. The first opening is disposed closer to the display area than the first contact hole.
