Patent ID: 8648383

Claim:
A light emitting device comprising: a substrate; a light emitting structure on the substrate, 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; an opening portion disposed in the light emitting structure; a first electrode disposed in the opening portion and contacted with a portion of the first conductive type semiconductor layer; an insulating layer covering the first electrode; a second electrode on the insulating layer and connected to a portion of the second conductive type semiconductor layer; and a first electrode layer between the second electrode and the second conductive type semiconductor layer, wherein the first conductive type semiconductor layer includes a first sidewall and a second sidewall opposite to the first sidewall, wherein the opening portion includes a first opening adjacent to the first sidewall and a second opening adjacent to the second sidewall, wherein a width of the first opening is greater than a width of the second opening.
