Abstract: A display panel including a glass substrate having an opening area, and a display area at least partially surrounding the opening area; a thin film transistor on the display area including a semiconductor layer and a gate electrode; a display element electrically connected to the thin film transistor; a multi-layer including an insulating layer and a lower insulating layer. The insulating layer is between the glass substrate and the display element and the lower insulating layer is between the glass substrate and the insulating layer; and a thin-film encapsulation layer covering the display element including an inorganic encapsulation layer and an organic encapsulation layer. The multi-layer includes a first groove between the opening area and the display area. A first width of a portion of the first groove in the lower insulating layer is greater than a second width of a portion of the first groove in the insulating layer.

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.
