1. A display device comprising:
a substrate;
a plurality of pixel electrodes on the substrate and spaced apart from each other; and
a plurality of light-emitting elements on the plurality of pixel electrodes, respectively, and
wherein the plurality of light-emitting elements comprise a first light-emitting element configured to emit a first light, a second light-emitting element configured to emit a second light, a third light-emitting element configured to emit a third light, and
wherein the first light, the second light, and the third light have different wavelengths from each other, and
wherein an active layer of the first light-emitting element has a same material as an active layer of the second light-emitting element, and
wherein an active layer of the third light-emitting element has a different material as the active layer of the first light-emitting element and the active layer of the second light-emitting element.
