Abstract:
1. A semiconductor light-emitting device comprising: a first conductive type semiconductor layer having a main surface; a plurality of vertical type light-emitting structures protruding beyond the main surface of the first conductive type semiconductor layer; a transparent electrode layer covering at least a portion of each of the plurality of vertical type light-emitting structures; and an insulation-filling layer on the transparent electrode layer, the insulation-filling layer extending parallel to the main surface of the first conductive type semiconductor layer to cover an upper portion of each of the plurality of vertical type light-emitting structures, wherein a selected one of the first conductive type semiconductor layer and the insulation-filling layer has an uneven outer surface opposite to an inner surface of the selected one, the inner surface facing the plurality of vertical type light-emitting structures, and at least a portion of the insulation-filling layer directly contacts the transparent electrode layer.
