Claim:
1. A light emitting device comprising: a substrate; a plurality of light emitting cells separated from each other and provided on the substrate, the plurality of light emitting cells including a first light emitting cell and a second light emitting cell, said second light emitting cell neighboring the first light emitting cell; a plurality of conductive interconnection layers, wherein a first one of the plurality of conductive interconnection layers electrically contacts the two neighboring light emitting cells, wherein each of the plurality of light emitting cells includes a light emitting structure including a first conductivity-type semiconductor layer, an active layer and a second conductivity-type semiconductor layer, a first electrode on the first conductivity-type semiconductor layer, a second electrode on the second conductivity-type semiconductor layer, and an etching area, in which the first conductivity-type semiconductor layer is exposed, formed by partially etching the light emitting structure, and an insulating layer along a first side surface of the light emitting structure of the first light emitting cell and along a second side surface of the light emitting structure of the second light emitting cell, wherein the second electrode includes a first part disposed in a first direction parallel with the first side surface and a second part disposed in a second direction differing from the first direction, wherein a length of the first part of the second electrode is greater than a length of the second part of the second electrode.
