Claim 0:
1. A semiconductor light-emitting device comprising:
a substrate having an upper surface and a lower surface;
a first insulating layer disposed on the upper surface of the substrate;
a plurality of light-emitting structures disposed on the first insulating layer and spaced apart from each other, each of the plurality of light-emitting structures comprising a first semiconductor layer, an active layer, and a second semiconductor layer;
a plurality of optical layers, each filling a groove that is formed in an upper surface of the second semiconductor layer of each of the plurality of light-emitting structures;
a plurality of first electrodes penetrating the substrate and electrically connected to the first semiconductor layer of each of the plurality of light-emitting structures, respectively;
a plurality of second insulating layers disposed on side surfaces of each of the plurality of light-emitting structures, respectively; and
a second electrode connected to the plurality of light-emitting structures, the second electrode being disposed on the second semiconductor layer of each of the plurality of light-emitting structures and each of the plurality of second insulating layers,
wherein, in a plan view, a planar area of each of the plurality of optical layers is less than a planar area of each corresponding first electrode, and
wherein, in a side cross-sectional view, a maximum width of the first semiconductor layer is less than a maximum width of each corresponding first electrode.
