1. A display panel comprising:
a substrate including a top surface and a bottom surface, the substrate having a through hole passing from the top surface to the bottom surface;
a first transistor in a display area and electrically connected to a scan line and a data line;
a second transistor in the display area and electrically connected the first transistor;
an organic insulating layer in the display area and a non-display area between the display area and the through hole, wherein the organic insulating layer includes a groove in the non-display area;
a light-emitting diode in the display area, the light-emitting diode comprising a pixel electrode on the organic insulating layer, an opposite electrode on the pixel electrode, and an intermediate layer between the pixel electrode and the opposite electrode; and
a metal layer in the non-display area, wherein the metal layer is on the organic insulating layer and comprises a tip protruding toward a center of the groove,
wherein the opposite electrode or at least one organic material layer of the intermediate layer is separated to a plurality of portions by the tip of the metal layer, and one of the plurality of portions is on the metal layer and an other of the plurality of portions is in the groove, and
wherein the organic insulating layer is interposed between the first and second transistor and the pixel electrode of the light-emitting diode in the display area.
