1. A display device comprising:
a first substrate;
a plurality of light-emitting elements on the first substrate and spaced from each other, wherein each of the plurality of light-emitting elements extends in a thickness direction of the first substrate;
a common electrode on the first substrate and the plurality of light-emitting elements;
a first insulating layer on the common electrode and the plurality of light-emitting elements; and
a plurality of first reflective layers on side surfaces of corresponding ones of the plurality of light-emitting elements with the first insulating layer therebetween, the first reflective layer being spaced from the common electrode and the plurality of light-emitting elements with the first insulating layer therebetween,
wherein the common electrode is in contact with a portion of the side surface of each of the plurality of light-emitting elements,
wherein adjacent ones of the plurality of first reflective layers respectively around corresponding adjacent ones of the plurality of light-emitting elements are spaced from each other, and
wherein the common electrode, the first insulating layer, and a first reflective layer of the plurality of first reflective layers partially overlap each other in a first direction perpendicular to the thickness direction of the first substrate.
