A light emitting element according to an embodiment of the present invention comprises a first conductive-type semiconductor layer including a contact region on the lower surface thereof, a light emitting structure which includes a mesa including a second conductive-type semiconductor layer and an active layer, a second electrode, a first insulation layer, an electrode cover layer, a first electrode, a second insulation layer, and a support structure. In addition, the mesa may include a body part and a plurality of protrusion parts protruding from the body part, the contact region may be disposed between the protrusion parts, and a part of the contact region may overlap with a second metal bulk in the vertical direction. Accordingly, current spreading efficiency can be improved, and thus luminance efficiency can be more improved.
