Abstract: A display device and a method of manufacturing the same are provided. A display device includes: a substrate including a plurality of pixels; a first electrode and a second electrode spaced apart from each other on the substrate; a light emitting element located between the first electrode and the second electrode; and a conductive pattern on the light emitting element. The light emitting element includes a first semiconductor layer, a second semiconductor layer, and an active layer between the first semiconductor layer and the second semiconductor layer, and the conductive pattern overlaps the active layer and does not overlap the first semiconductor layer or the second semiconductor layer.
