Display panel
A display panel includes an opening area, a display area surrounding at least a portion of the opening area, and an intermediate area between the opening area and the display area in a plan view, a light-emitting diode arranged on a substrate in the display area and including a pixel electrode, an opposite electrode, and an intermediate layer, a support layer arranged on the substrate in the intermediate area, an organic insulating layer arranged on the substrate and the support layer and having a groove corresponding to the support layer, a metal layer arranged on the organic insulating layer and having a protrusion tip, and a cover layer including a first cover portion covering an upper surface and a side surface of the metal layer and a second cover portion arranged in the groove. The functional layer extends to the intermediate area and includes a dummy functional layer.
