Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A display device comprising:
a first substrate;
a first electrode disposed on the first substrate;
a second electrode spaced apart from the first electrode;
a first insulating layer disposed on the first substrate and overlapping parts of the first and second electrodes; and
a plurality of light-emitting elements disposed on the first insulating layer, each of the plurality of light-emitting elements including a first end portion disposed on the first electrode and a second end portion disposed on the second electrode, each of the plurality of light-emitting elements including:
a first semiconductor layer which is doped to have a first polarity;
a second semiconductor layer which is doped to have a second polarity different from the first polarity;
a light-emitting layer which is disposed between the first and second semiconductor layers;
a shell layer which is formed on a side surface of the first semiconductor layer, a side surface of the light-emitting layer, and a side surface of the second semiconductor layer, the shell layer including a divalent metal element; and
an insulating film which is disposed to cover an outer surface of the shell layer and to surround at least the side surface of the light-emitting layer,

wherein the shell layer includes at least one of ZnS, ZnSe, MgS, MgSe, ZnMgS, and ZnMgSe.
