Abstract: A semiconductor light-emitting device includes a first conductive type semiconductor layer having a main surface, a plurality of vertical type light-emitting structures protruding upward from the first conductive type semiconductor layer; a transparent electrode layer covering the plurality of vertical type light-emitting structures; and an insulation-filling layer disposed on the transparent electrode layer. The insulation-filling layer extends parallel to the first conductive type semiconductor layer so as to cover the plurality of vertical type light-emitting structures. A selected one of the first conductive type semiconductor layer and the insulation-filling layer, which is disposed on a light transmission path through which light generated from the plurality of vertical type light-emitting structures is radiated externally, has an uneven outer surface. The uneven outer surface is opposite to an inner surface of the selected one, and the inner surface faces the plurality of vertical type light-emitting structures.
