A display device comprises a pixel. The pixel comprises: a first light-emitting element, a second light-emitting element, and a third light-emitting element which are arranged at equal intervals along a first direction; first pixel electrodes which are arranged along the first direction and make contact with the first to third light-emitting elements; and second pixel electrodes which are arranged along the first direction so as to form pairs with the first pixel electrodes, and make contact with the first to third light-emitting elements. The first to third light-emitting elements each comprise active layers disposed on a first semiconductor layer, a second semiconductor layer, and between the first semiconductor layer and the second semiconductor layer, and comprise a mesa region where one of the first and second semiconductor layers is partially exposed by means of the other. The mesa region of the first light-emitting element makes contact with one of the first pixel electrodes.
