Abstract:
1. A semiconductor light emitting device, comprising: a first semiconductor layer including a layer of a first conductivity type; a second semiconductor layer apart from a first direction, the second semiconductor layer including a layer of a second conductivity type different from the first conductivity type; and a light emitting layer provided between the first semiconductor layer and the second semiconductor layer, the first semiconductor layer having a first surface and a second surface, the second surface opposing the light emitting layer, the first surface being opposite to the second surface, the first surface including a plurality of bottom faces and an apical face, a distance between one of the bottom faces and the second surface in the first direction being less than a distance between the apical face and the second surface in the first direction, the bottom faces includes a first face and a second face nearest to the first face, the first face having a first centroid, the second face having a second centroid, the first centroid aligning with the second centroid along a second axis, and hb and rb satisfying where
