Classification: CPC H | IPC H

Claim 7:
8. A display device comprising:
a pixel circuit;
an insulating layer covering the pixel circuit;
a first electrode on the insulating layer, and electrically connected to the pixel circuit;
a second electrode on the insulating layer, and spaced apart from the first electrode; and
a plurality of light emitting elements electrically connected to the first electrode and the second electrode, the plurality of light emitting elements comprising:
a body comprising an insulating film covering a side surface of a semiconductor layer and an active layer, and comprising a metal oxide; and
a ligand comprising:
a head portion bonded to the insulating film at an exterior surface of the body, the head portion being a hydroxyl group, a thiol group, a catechol group, or a carboxyl group, wherein the exterior surface of the body is a surface that defines an outermost surface of the body;
an end portion spaced apart from the body, and having a positive or a negative charge; and
a chain portion connecting the head portion and the end portion.
