Abstract: A display device includes a substrate, a plurality of pixel electrodes on the substrate and spaced apart from each other, a plurality of light-emitting elements on the plurality of pixel electrodes, respectively, and a common electrode layer on the plurality of light-emitting elements and to which a common voltage is applied. The plurality of light-emitting elements include a first light-emitting element that is configured to emit first light according to a first driving current and a second light-emitting element that is configured to emit second light according to a second driving current. An active layer of the first light-emitting element is the same as an active layer of the second light-emitting element.
