The light emitting element layer may include a first electrode, a light emitting layer, and a second electrode. The second electrode may include a first portion that is not overlapped with the module hole and has a first thickness and a second portion between the module hole and the first portion and having a thickness that gradually increases in a direction toward the first portion. Thus, the display device may improve in durability in a hot and humid environment.
