Abstract:
1. A semiconductor light emitting device, comprising: a stacked structure including a first semiconductor layer with a first conductivity type, a light emitting layer, and a second semiconductor layer with a second conductivity type, the respective layers being stacked directly or indirectly on each other; a first electrode connected to the first semiconductor layer; a second electrode disposed on a first surface of the second semiconductor layer, the first surface of the second semiconductor layer being a flat surface; a first plurality of concavo-convex shapes provided in a second surface of the second semiconductor layer, the second surface of the second semiconductor layer being opposite to the first surface of second semiconductor layer; and a transparent conductive film having a third surface disposed on and in contact with the first plurality of concavo-convex shapes provided in the second surface of the second semiconductor layer, the transparent conductive film having a fourth surface that is opposite the third surface and a second plurality of concavo-convex shapes provided in the fourth surface, wherein the second plurality of concavo-convex shapes corresponds to the first plurality of concavo-convex shapes, and opposing surfaces of both the first semiconductor layer and the light emitting layer are flat surfaces.
