Light emitting device and light emitting device package having the same

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 and disposed in the opening portion;
• a second electrode on the light emitting structure and connected to a portion of the second conductive type semiconductor layer;
• and
• a first electrode layer connected to the second conductive type semiconductor layer and the second electrode;
• wherein the first electrode layer is disposed on a top surface of the second conductive type semiconductor layer and a top surface of the insulating layer,
• wherein the insulating layer is disposed between the first electrode and the first electrode layer,
• wherein the light emitting structure includes a first sidewall and a second sidewall spaced apart from the first sidewall,
• wherein the opening portion includes a first opening adjacent to the first sidewall and the second opening adjacent to the second sidewall,
• wherein the first opening has a width wider than that of the second opening,
• wherein the first electrode has a first part contacted with the insulating layer in the second opening and a second part exposed to an opening region of the insulating layer on the first opening, and
• wherein the second electrode is not vertically overlapped with the first electrode.
