Abstract: A display device includes a circuit layer disposed on a base layer, a pixel definition layer disposed on the circuit layer and provided with first, second, and third light emitting openings, and first, second, and third light emitting elements disposed on the circuit layer and including light emitting patterns disposed in the first, second, and third light emitting openings. The pixel definition layer has a first gap corresponding to a distance between the first and third light emitting openings and a second gap corresponding to a distance between the first and second light emitting openings. A difference between the first gap and the second gap is determined according to a difference in size of a shadow area of at least one of the light emitting patterns and a difference in deviation of a pixel position accuracy (PPA) of the at least one of light emitting patterns.
