Patent ID: 8723203

Claim:
A light emitting device comprising: a conductive layer; an electrode; a light emitting structure layer disposed between the electrode and the conductive layer, and the light emitting structure layer including a first semiconductor layer, a second semiconductor layer under the first semiconductor layer, and an active layer between the first semiconductor layer and the second semiconductor layer; and a light guide layer including a transmittive material between the first semiconductor layer and the electrode, wherein the electrode includes a first portion contacting at least one side surface of the light guide layer and a second portion extending from the first portion toward a top surface of the light guide layer, wherein a width of a lower surface of the light guide layer is less than a width of a top surface of the first semiconductor layer, wherein an entire top surface of the light guide layer contacts a lower surface of the second portion of the electrode, wherein the entire top surface of the light guide layer has a smaller area than a top surface of the electrode, wherein the light guide layer includes a first part and a second part opposite to the first part, wherein the first portion of the electrode is disposed between the first part of the light guide layer and the second part of the light guide layer, wherein the first part of the light guide layer includes a first side surface that contacts the first portion of the electrode and a second side surface that does not contact the electrode, wherein the second part of the light guide layer includes a third side surface that contacts the first portion of the electrode and a fourth side surface that does not contact the electrode, and wherein the second side surface of the first part is disposed in opposing relation to the fourth side surface of the second part.
