A second power wire is disposed in the non-display area and includes an extension portion extending in a second direction crossing the first direction, the extension portion located between the first and second wirings. A protective layer covers the first and second power wires, and a bridge wire is disposed on the protective layer and configured to electrically connect the first wiring to the second wiring. A vertical gap between the bridge wire and the extension portion is greater than a vertical gap between the bridge wire and the first wiring or a vertical gap between the bridge wire and the second wiring.
