1. A display device comprising:
a first pixel circuit unit, a second pixel circuit unit, a third pixel circuit unit, and a fourth pixel circuit unit spaced from one another;
a first pixel electrode on the first pixel circuit unit;
a second pixel electrode on the second pixel circuit unit;
a third pixel electrode on the third pixel circuit unit;
a fourth pixel electrode on the fourth pixel circuit unit;
a first light-emitting element electrically connected to the first pixel electrode, the first light-emitting element being configured to emit first light;
a second light-emitting element electrically connected to the second pixel electrode, the second light-emitting element being configured to emit second light that has a different color from the first light; and
a third light-emitting element electrically connected to the third pixel electrode, the third light-emitting element being configured to emit third light that has a different color from the first light and the second light, wherein:
a length of the first light-emitting element in a first direction is greater than each of a length of the second light-emitting element and a length of the third light-emitting element in the first direction;
a length of the first light-emitting element in a second direction is greater than a length of the third light-emitting element in the second direction;
the lengths of the second light-emitting element and the third light-emitting element in the first direction are the same as each other and the second light-emitting element and the third light-emitting element are immediately adjacent to each other in the second direction; and
the second direction is orthogonal to the first direction.
