1. A display device comprising:
light-emitting elements arranged on a circuit board comprising pixel electrodes, and extending in a thickness direction of the circuit board, wherein the 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; and
a first semiconductor layer,
wherein the first semiconductor layer of each of the light-emitting elements is connected to a respective one of the pixel electrodes; and
connection electrodes respectively between the first semiconductor layers of the light-emitting elements and the pixel electrodes,
wherein the first light-emitting element and the second light-emitting element are on different layers,
wherein a width of the first light-emitting element is greater than a width of the second light-emitting element, and
wherein a length of the connection electrode corresponding to the first light-emitting element is greater than a length of the connection electrode corresponding to the second light-emitting element.
