1. A light-emitting element extending in one direction, comprising:
a semiconductor core comprising a main body extending in the one direction, a first end connected to one side of the main body and having an inclined side surface, and a second end connected to an other side of the main body and having a width less than that of the main body; and
an insulation film around at least a portion of an outer surface of the semiconductor core,
wherein the insulation film comprises a first insulation film around the first end of the semiconductor core and a second insulation film around the second end of the semiconductor core, and
a diameter of an outer surface of the first insulation film is the same as a diameter of an outer surface of the second insulation film.
