Classification: CPC H | IPC H

Claim 10:
11. A display device comprising:
a first pixel electrode and a second pixel electrode which are spaced apart from each other in a first direction on a substrate and extend in a second direction different from the first direction; and
light-emitting elements which are disposed between the first pixel electrode and the second pixel electrode and each include a first end portion and a second end portion in a length direction of light-emitting elements;
a first contact electrode disposed on the first pixel electrode and the first end portion of each of the light-emitting elements, and
a second contact electrode disposed on the second pixel electrode and the second end portion of each of the light-emitting elements, wherein
the first contact electrode is electrically connected to the first pixel electrode,
the second contact electrode is electrical connected to the second pixel electrode,
each of the light-emitting elements includes:
a first electrode corresponding to the first end portion;
a first semiconductor layer disposed on the first electrode;
an active layer disposed on the first semiconductor layer;
a second semiconductor layer disposed on the active layer; and
a second electrode corresponding to the second end portion and including a first layer disposed on the second semiconductor layer and a second layer disposed on the first layer,

each of the first and second end portions overlaps one of the first and second pixel electrodes in a cross-section view,
a contact area between the first contact electrode and the first electrode is substantially the same as the contact area between the second contact electrode and the second electrode, and
the first layer and the second layer include a transparent conductive material.
