Abstract

A light emitting device and a method of manufacturing the same are disclosed. The light emitting device includes a buffer layer formed on a substrate, a nitride semiconductor layer including a first semiconductor layer, an active layer, and a second semiconductor layer, which are sequentially stacked on the buffer layer, a portion of the first semiconductor layer being exposed to the outside by performing mesa etching from the second semiconductor layer to the portion of the first semiconductor layer, and at least one nanocone formed on the second semiconductor layer.
