Abstract: A display device may include a substrate, an organic light emitting layer overlapping the substrate and including an opening, and a holed insulating layer positioned between the substrate and the organic light emitting layer. The holed insulating layer may include a first through hole, a first groove, and a first undercut. A position of the opening may overlap a position of the first groove. The first groove may surround the first through hole in a plan view of the display device. The first undercut may surround the first groove in the plan view of the display device.
