Abstract

A light emitting device may be provided that includes a substrate, a light emitting structure, a first electrode on a part of the first semiconductor layer, an electrode layer on the second conductive semiconductor layer, an insulating layer on the electrode layer, a second electrode on the electrode layer, a support member on the insulating layer, a first connection electrode connected to the first electrode, and a second connection electrode connected to the second electrode. The insulating layer is disposed on a side surface of the light emitting structure and the part of the first semiconductor layer. The insulating layer includes a first layer and a second layer having a different material from the first layer. The first layer of the insulating layer has a refractive index different from the second layer of the insulating layer.
