Abstract: A display panel includes a substrate comprising an opening. A plurality of light-emitting diodes is arranged in a display area surrounding the opening. A plurality of grooves is located in a middle area between the opening and the display area and disposed on at least one inorganic insulating layer on the substrate. At least one groove of the plurality of grooves includes a tip protruding towards a center of the at least one groove. The tip includes a transparent layer and a metal pattern layer disposed on the transparent layer. The metal pattern layer includes a groove portion corresponding to an edge of the tip. The groove portion exposes at least a portion of an upper surface of the transparent layer.
