Patent ID: 8860055

Claim:
A light emitting device, comprising: a second electrode layer; a light emitting structure comprising an n-type semiconductor layer, a p-type semiconductor layer, and an active layer between the n-type semiconductor layer and the p-type semiconductor layer; at least one current blocking layer disposed between the second electrode layer and the light emitting structure; a first electrode layer including a body and a protrusion extending from the body towards the n-type semiconductor layer with a triangular cross-section; and a reflection layer formed between the protrusion of the first electrode layer and the n-type semiconductor layer, the reflection layer being formed at a bottom surface of the body and at an inclined surface of the protrusion, wherein a width of the reflection layer is identical to a width of the first electrode layer, wherein the reflection layer directly contacts the n-type semiconductor layer, wherein the n-type semiconductor layer has a recess having an inclined surface, and wherein the reflection layer directly contacts the inclined surface of the recess; wherein the first electrode layer has a first bottom surface with the protrusion and a second bottom surface surrounding the first bottom surface, and wherein the reflection layer has a first portion between the recess of the n-type semiconductor layer and the first bottom surface of the first electrode layer and a second portion between a portion of a top surface of the n-type semiconductor layer and the second bottom surface of the first electrode layer; and wherein the current blocking layer comprises an oxide-based material.
