Abstract: A display device includes a substrate including unit pixel areas repeatedly arranged in a plan view, first, second, and third light emitting devices disposed in each of the unit pixel areas on the substrate and emitting light of different colors, a pixel defining layer defining a first pixel opening positioned above a first pixel electrode of the first light emitting device, a second pixel opening positioned above a second pixel electrode of the second light emitting device, and a third pixel opening positioned above a third electrode of the third light emitting device, partition patterns disposed on the first to third light emitting devices and partially covering the first, second, and third pixel openings, and in a plan view, the three pixel openings have the same overlap ratio. An overlap ratio is a ratio of an area of a pixel opening that is covered by the partition patterns to a total area of the pixel opening.
