Abstract
A display device according to an embodiment of the present invention includes a display panel having a through hole in a display area including a plurality of pixels. The display panel includes a substrate, and an organic light-emitting diode including a first electrode provided above the substrate for each of the pixels, a second electrode provided over the plurality of pixels, and an organic electroluminescence layer arranged between the first electrode and the second electrode. The through hole penetrates at least the second electrode, and the second electrode includes an oxidized part exposed at an inner surface of the through hole.
