Abstract

Disclosed are a light emitting device, a method of manufacturing the same, a light emitting device package, and a lighting system. The light emitting device includes: a substrate; a first conductive semiconductor layer on the substrate; an active layer on the first conductive semiconductor layer; a second conductive semiconductor layer; and a nitride semiconductor layer having a refractive index less than a refractive index of the second conductive semiconductor layer on the second conductive semiconductor layer.

First claim

What is claimed is:

1. A light emitting device comprising:
a substrate;
a first conductive semiconductor layer on the substrate;
an active layer on the first conductive semiconductor layer;
a second conductive semiconductor layer on the active layer; and
a nitride semiconductor layer having a refractive index less than a refractive index of the second conductive semiconductor layer on a top surface of the second conductive semiconductor layer,
wherein the nitride semicon…
