Classification: CPC G  H | IPC G  H

Claim 10:
11. A display device comprising:
a substrate;
a plurality of pixel electrodes on the substrate and spaced apart from each other;
a plurality of light-emitting elements respectively on the plurality of pixel electrodes; and
a common electrode layer on the plurality of light-emitting elements and to which a common voltage is applied,
wherein the plurality of light-emitting elements comprise:
a first light-emitting element that is configured to emit first light according to a first driving current;
a second light-emitting element that is configured to emit second light according to a second driving current; and
a third light-emitting element that is configured to emit third light according to a third driving current,
wherein a current density of the first driving current is the same regardless of a gray level of the first light-emitting element, and a current density of the second driving current is the same regardless of a gray level of the second light-emitting element, and
a current density of the third driving current is adjusted according to a gray level of the third light-emitting element.
