摘要： 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 2 μm.

摘要： A display apparatus includes a thin film transistor disposed in a display area of a substrate and a display device in the display area that is electrically connected to the thin film transistor, an encapsulation layer that protects the display device, at least one through portion formed in the display area that vertically penetrates the substrate and a plurality of layers stacked on the substrate, and a first groove and a second groove that are spaced apart from each other and that surround the at least one through portion. A flow-restriction portion is disposed in a region between the first groove and the second groove that protrudes upwards from the substrate and confines an organic encapsulation layer of the encapsulation layer.
