Abstract: A display apparatus includes a display panel, an electrode, a first wiring, a second wiring, a first contact hole, a second contact hole and a first resistor. The display panel includes an active area to display an image and a peripheral area adjacent to the active area. The electrode is in the active area. The first wiring is in the peripheral area and configured to apply a power voltage to the electrode. The second wiring is in the peripheral area and configured to apply the power voltage to the electrode. The first contact hole connects the electrode and the first wiring. The second contact hole connects the electrode and the second wiring. The first resistor is connected between the first wiring and the second wiring.
