1. A display device, comprising:
a first substrate;
a conductive layer comprising a first voltage line configured to supply a first voltage, a second voltage line configured to supply a second voltage, and a third voltage line spaced from each other along a first direction on the first substrate, the first voltage being different from the second voltage;
an interlayer insulating layer on the conductive layer;
first and second electrodes on the interlayer insulating layer and spaced from each other along the first direction;
a plurality of light emitting elements having at least one end on and overlapping the first electrode or the second electrode;
a first contact electrode on first ends of some of the plurality of light emitting elements and not overlapping the first electrode and the second electrode; and
a second contact electrode on second ends of some of the plurality of light emitting elements,
wherein the first electrode and the second electrode do not overlap the first voltage line and the third voltage line, respectively,
wherein the plurality of light emitting elements comprises first light emitting elements on the first electrode and the first voltage line, and second light emitting elements on the second electrode and the third voltage line, and
wherein the first voltage line, the second voltage line, and the third voltage line are located at a layer that is different from a layer in which the first contact electrode is located.
