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 2 μm.

Abstract: A display apparatus includes a thin-film transistor on a substrate, a planarization film on the thin-film transistor, a light-emitting element on the planarization film, connected to the thin-film transistor, and including a first electrode, an intermediate layer and a second electrode in order from the thin-film transistor, an insulating layer overlapping an edge of the first electrode, a metal stacked structure on the insulating layer, including a first sub-metal layer and a second sub-metal layer which is closer to the insulating layer than the first sub-metal layer, and a low reflection layer located on the metal stacked structure. The second electrode includes a first portion on the intermediate layer, and a second portion which is on the reflection layer and disconnected from the first portion at the metal stacked structure.

Abstract: 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.

Abstract: A display device may include a base substrate including display and peripheral regions adjacent to each other, an organic light emitting device, and an encapsulation member. A module hole, a first blocking groove, and a second blocking groove may be defined in the base substrate. The module hole may be defined in the display region to penetrate the base substrate from a front surface to a rear surface. The first and second blocking grooves may be provided to enclose the module hole. A distance from the rear surface of the base substrate to a top surface of the encapsulation member between the first and second blocking grooves is smaller than that in a region outside the second blocking groove.
