Abstract
A light emitting device includes a substrate, a plurality of light emitting cells separated from each other and disposed on the substrate, and a plurality of conductive interconnection layers electrically connecting two neighboring light emitting cells. Each light emitting cell 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, a second electrode, and an etching area. The light emitting structure further includes a first side surface and a second side surface, and if a width between the first side surface and the second side surface is defined as W, the second electrode is disposed in an area between a position separated from the first side surface by ⅕ W and a position separated from the first side surface of the light emitting structure by ½ W.
