1. A display device comprising:
a substrate;
first sub-pixels, second sub-pixels, and third sub-pixels on the substrate, the second sub-pixels being adjacent to the first sub-pixels, and the third sub-pixels being spaced from the first sub-pixels with a respective one of the second sub-pixels therebetween;
first electrodes and second electrodes on the substrate and located in the sub-pixels;
first light-emitting elements, second light-emitting elements, and third light-emitting elements on the first electrodes and the second electrodes and located in the sub-pixels, each of the light-emitting elements comprising a first end and a second end opposite to the first end; and
a first connection electrode, a second connection electrode, a third connection electrode, and a fourth connection electrode on the first to third light-emitting elements and located in the sub-pixels,
wherein in the first sub-pixel:
the first electrodes are extended in a first direction and are spaced from one another in a second direction crossing the first direction;
the second electrodes are extended in the first direction and are spaced from one another with the first electrode located on an opposite side in the second direction therebetween;
the first light-emitting elements are between the first electrode located on the opposite side in the second direction and the second electrode located on the opposite side in the second direction,
the second light-emitting elements are between the first electrode located on the opposite side in the second direction and the second electrode located on one side in the second direction,
the third light-emitting elements are between the first electrode located on the one side in the second direction and the second electrode located on the one side in the second direction,
the first connection electrode is in contact with the first end of the first light-emitting element,
the second connection electrode is in contact with the second end of the third light-emitting element,
the third connection electrode is in contact with the second end of the first light-emitting element and the first end of the second light-emitting element, and
the fourth connection electrode is in contact with the second end of the second light-emitting element and the first end of the third light-emitting element,
wherein the first sub-pixel, the second sub-pixel, and the third sub-pixel are repeatedly arranged along the second direction,
wherein the first end of the first light-emitting element and the first end of the third light-emitting element face the opposite side in the second direction, and
wherein the first end of the second light-emitting element faces the one side in the second direction opposite to the opposite side in the second direction.
