Display panel including a non-display area within a display area

A display panel, comprising:

• a substrate including a first area, a second area at least partially surrounding the first area in a plan view, and a third area disposed between the first area and the second area in the plan view;
• a plurality of display elements, each disposed in the second area and including a pixel electrode, an opposite electrode, and an emission layer disposed between the pixel electrode and the opposite electrode;
• a plurality of wirings detouring around an edge of the first area in the third area in the plan view;
• at least one groove disposed in the third area;
• a first electrode layer covering at least a portion of the plurality of wirings;
• and
• a second electrode layer disposed over the first electrode layer,
• wherein the first area is a transmission area and is inside the second area,
• wherein in the third area, the first electrode layer includes a plurality of holes that are spaced apart from each other and the second electrode layer contacts the first electrode layer between neighboring holes of the plurality of holes, and
• wherein in the third area, the plurality of wirings is disposed below a region in which the first electrode layer directly contacts the second electrode layer in a cross-sectional view.
