Abstract
There are provided a light emitting device and a method of manufacturing the same. A light emitting device according to the present invention includes a substrate; an N-type semiconductor layer, an active layer and a P-type semiconductor layer, sequentially formed on the substrate; one or more trenches formed to expose the N-type semiconductor layer by partially removing at least the P-type semiconductor and active layers; a first insulating layer formed on sidewalls of the trenches; and a conductive layer filled in the trenches having the first insulating layer formed therein. According to the present invention, it is possible to obtain a characteristic of uniform current diffusion, and thus, light is uniformly emitted to thereby enhance the light emitting efficiency.
