1. A display device comprising:
a first voltage wiring line extending in a first direction;
a data line spaced apart from the first voltage wiring line and extending in the first direction;
a scan line extending in a second direction different from the first direction;
a sensing line spaced apart from the scan line and extending in the second direction;
a first internal bank and a second internal bank on the first voltage wiring line and the data line and extending in the first direction, the first internal bank and the second internal bank being spaced apart from each other and facing each other;
a first electrode on the first internal bank and extending in the first direction;
a second electrode on the second internal bank and extending in the first direction;
a plurality of light emitting elements between the first electrode and the second electrode,
a reference voltage wiring line extending in the first direction and spaced apart from the data line in the second direction; and
a reference voltage distribution line extending in the second direction and spaced apart from the sensing line in the first direction,
wherein each of the plurality of light emitting elements comprises a semiconductor core comprising a light emitting layer, and an insulating film around at least a portion of an outer surface of the semiconductor core, and
wherein the data line is between the first voltage wiring line and the reference voltage wiring line, and the sensing line is between the scan line and the reference voltage distribution line.
