Abstract: A light emitting element includes 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 layer surrounding the semiconductor core, the first electrode layer and the second electrode layer. The second end of the semiconductor core has a diameter smaller than a diameter of the main body part.

Abstract: A light emitting diode includes a first end and a second end facing each other, a current blocking layer, a first semiconductor layer, an active layer, a second semiconductor layer, and an insulating film surrounding outer circumferential surfaces of the first semiconductor layer, the active layer, and the second semiconductor layer and exposing at least a portion of the current blocking layer and at least a portion of the first semiconductor layer at the second end. The current blocking layer, the first semiconductor layer, the active layer, and the second semiconductor layer are sequentially disposed in a direction from the second end to the first end.
