Abstract: A display panel includes a peripheral region adjacent to a display region. The display region includes a hole peripheral region, and a recessed region is overlapped with the hole peripheral region. The display panel also includes a barrier layer with a penetrating opening overlapped with the recessed region, a circuit layer on the barrier layer and including a transistor and insulating layers, and a device layer including an organic light emitting area coupled to the circuit layer. In addition, a module hole is overlapped with the hole peripheral region and penetrates the base substrate, and a first groove is overlapped with the hole peripheral region and corresponds to a portion of the base substrate that is recessed from a top surface of the barrier layer and that encloses the module hole. The insulating layers include inorganic layers and an organic layer having side portions enclosing the module hole.

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.
