Classification: CPC H | IPC H

Claim 13:
14. A display device comprising:
a substrate;
a first electrode and a second electrode, spaced from each other along a first direction on one surface of the substrate, the first electrode and the second electrode extending in a second direction different from the first direction; and
a plurality of light emitting elements located between the first electrode and the second electrode, each of the plurality of light emitting elements comprising one end portion electrically connected to the first electrode and the other end portion electrically connected to the second electrode,
wherein each of the light emitting elements comprises:
a first semiconductor layer;
an active layer on the first semiconductor layer;
a second semiconductor layer on the active layer; and
an insulating film surrounding an outer surface of at least one of the first semiconductor layer, the active layer, and the second semiconductor layer, and
wherein the insulating film comprises a zinc oxide (ZnO) thin film layer doped with at least one of Group III transition metals including yttrium (Y), scandium (Sc), lanthanum (La), actinium (Ac), lutetium (Lu) ruthcnium (Ru), and lawrencium (Lr).
