Claim:
1. A light emitting device, comprising: a substrate; a light emitting structure disposed on the substrate and the light emitting structure including a first conductive type semiconductor layer, an active layer on the first conductive type semiconductor layer, and a second conductive type semiconductor layer on the active layer; a first transmissive electrode layer disposed on a top surface of the first conductive type semiconductor layer; a second transmissive electrode layer disposed on a top surface of the second conductive type semiconductor layer; a first electrode disposed on the first transmissive electrode layer; and a second electrode disposed on the second transmissive electrode layer, wherein at least one portion of the top surface of the second conductive type semiconductor layer is exposed by forming an opening through the second transmissive electrode layer, wherein at least one portion of the top surface of the first conductive type semiconductor layer is exposed by forming an opening through the first transmissive electrode layer, wherein the first electrode has a first portion and an second portion under the first portion, wherein a width of the first portion is wider than a width of the second portion, and wherein both of the first portion and the second portion are electrically in contact with the first transmissive electrode layer.
