Abstract:
1. A semiconductor light emitting device comprising: a substrate comprising a top surface and a bottom surface; a light emitting structure on the substrate, disposing closer to the substrate top surface than the substrate bottom surface, and comprising an n-type conductive type semiconductor layer, a p-type conductive type semiconductor layer on the n-type conductive type semiconductor layer, and an active layer between the n-type and p-type conductive type semiconductor layers; a transparent electrode layer on the p-type conductive type semiconductor layer; a first electrode disposed on the n-type conductive type semiconductor layer; and a second electrode disposed on and contacting to the transparent electrode layer, wherein the substrate has side surfaces extending from the substrate bottom surface to the substrate top surface, the side surfaces inclined outwardly as the substrate extends in a direction from the substrate bottom surface to the substrate top surface, wherein the transparent electrode layer covers more than 50% of a total area of a top surface of the p-type conductive type semiconductor layer, and wherein a part of light generated by the light emitting structure is emitted to outside via the transparent electrode layer.
