Abstract: A display device comprises a substrate, a pixel electrode, a common electrode, an intermediate layer, a semiconductor layer, a metal layer, and an organic layer. The substrate includes an opening area, a peripheral area surrounding the opening area, and a display area surrounding the peripheral area. The pixel electrode overlaps the display area. The common electrode overlaps the pixel electrode. The intermediate layer is disposed between the pixel electrode and the common electrode and includes a light emitting layer and a functional layer. The semiconductor layer overlaps the peripheral area and is spaced from the display area. The metal layer overlaps the semiconductor layer. The organic layer is disposed between the semiconductor layer and the metal layer. The common electrode, the functional layer, and the metal layer respectively have a first opening, a second opening, a third opening overlapping each other and overlapping the semiconductor layer.
