Claim Text:
1. A light emitting device comprising: a substrate; a light emitting structure on the substrate comprising: a first electrode on the first conductive type semiconductor layer; a second electrode on the second conductive type semiconductor layer; and a light extraction structure disposed above an edge area of the second conductive type semiconductor layer, wherein the second electrode is disposed on a top surface of the second conductive type semiconductor layer, wherein the light extraction structure is not disposed between the first electrode and the second electrode, wherein the light extraction structure includes a first wall, a second wall and a third wall, wherein at least two of the walls of the light extraction structure have an inner surface inclined at an acute angle, and wherein the second electrode comprises an electrode pad and a transparent electrode layer disposed between the electrode pad and the second conductive type semiconductor layer.
