Abstract:
1. A light emitting device, comprising: a substrate; and a light emitting structure on the substrate, comprising a first semiconductor layer, a second semiconductor layer on the first semiconductor layer, and an active layer between the first and second semiconductor layers, wherein the substrate has at least one side surface extending outwardly as the substrate extends in a direction from a bottom surface of the substrate to a top surface of the substrate, wherein the at least one side surface includes a first portion, a transition portion connected to the first portion, and a second portion connected to the transition portion, the first portion provides a first obtuse inclination angle with reference to the bottom surface of the substrate and the transition portion provides a second obtuse inclination angle with reference to the bottom surface of the substrate, the second obtuse inclination angle is larger than the first obtuse inclination angle, and wherein the second portion includes a vertical side surface with reference to the bottom surface of the substrate.
