Abstract: A display panel includes a substrate having an opening area, and a display area at least partially surrounding the opening area. Display elements are arranged in the display area. The display elements includes a pixel electrode, an opposite electrode, and an intermediate layer interposed therebetween. A multilayer film includes a first insulating layer between the substrate and the pixel electrode and a second insulating layer, of a different material, on the first insulating layer. A thin film encapsulation layer covers the display elements and includes at least one organic encapsulation layer and at least one inorganic encapsulation layer. The multilayer film includes a first groove disposed between the opening area and the display area. The first groove has an undercut structure in which a lower width of the first groove is greater than an upper width of the first groove.
