Abstract:
1. A light emitting device comprising: a first conductive semiconductor layer; an active layer on the first conductive semiconductor layer; a second conductive semiconductor layer on the active layer; a passivation layer surrounding entire side surfaces of at least one layer of the first conductive semiconductor layer, the active layer, or the second conductive semiconductor layer; a first light extracting structure layer having a concave-convex structure on the passivation layer; a first electrode layer on a portion of a top surface of the first conductive semiconductor layer; a growth substrate under the first conductive semiconductor layer; a reflective layer under the growth substrate; and a second light extracting structure layer having a concave-convex structure between the growth substrate and the reflective layer, wherein an entire side surface of the first electrode layer is surrounded by the passivation layer and the first light extracting structure layer, wherein the first light extracting structure layer includes a material that is different from the passivation layer, and wherein the first light extracting structure layer and the second light extracting structure layer include a same material.
