Abstract: A display panel includes a plurality of display elements arranged in a display area, an opening, a multi-layer including a first layer and a second layer disposed on the first layer, and a groove. Each display element includes a pixel electrode, an emission layer disposed on the pixel electrode, and an opposite electrode disposed on the emission layer. The display area surrounds the opening. The groove is located between the opening and the display area. The groove has an undercut cross-section that is concave in a thickness direction of the multi-layer, the second layer includes a pair of tips that protrude toward a center of the groove, and a length of each tip is less than about 2μm.

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.
