Abstract:
1. A semiconductor light emitting device comprising: a substrate; a light emitting structure on the substrate comprising a first semiconductor layer including a first portion, a second portion and a third portion, an active layer on the first portion of the first semiconductor layer, and a second semiconductor layer on the active layer; a transparent electrode layer on the second semiconductor layer of the light emitting structure; a first electrode on a second portion of the first semiconductor layer; and a second electrode on the transparent electrode layer, wherein the transparent electrode layer has a single layer having a transparent conductive oxide layer, wherein the second electrode comprises a metal layer and a reflective layer disposed on the metal layer, the metal layer directly contacting at least a portion of a top surface of the single layer, wherein the second portion and the third portion of the first semiconductor layer do not overlap with the active layer in a vertical direction, wherein the first electrode is not on the third portion of the first semiconductor layer, wherein a width of the third portion is narrower than a width of the second portion, wherein the transparent electrode layer has a first top surface on which the metal layer is disposed and a second top surface on which the metal layer is not disposed such that light from the active layer is emitted toward the outside through the second top surface of the transparent electrode layer, wherein the second electrode comprises two or more divided parts, at least portions of the two or more divided parts of the second electrode being spaced apart from each other, and wherein at least a portion of the second electrode directly contacts the transparent electrode layer.
