1. A light emitting element comprising:
a semiconductor core having at least a partial region extending in a direction and including:
a first end;
a second end; and
a main body part between the first end and the second end;
a first electrode layer surrounding the second end of the semiconductor core;
a second electrode layer surrounding at least the first end of the semiconductor core and spaced apart from the first electrode layer; and
an insulating film surrounding the semiconductor core, the first electrode layer, and the second electrode layer,
wherein the second end of the semiconductor core has a diameter smaller than a diameter of the main body part.
