Abstract:
1. A light emitting device comprising: a light emitting structure including a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer; a substrate under the light emitting structure; a first reflective layer having a plurality of dielectric layers including a first dielectric layer having a first refractive index under the substrate, and a second dielectric layer having a second refractive index different from the first refractive index under the first dielectric layer, the first reflective layer having a bottom most surface; a second reflective layer under the first reflective layer, the second reflective layer having a refractive index lower than the refractive index of each dielectric layer of the first reflective layer; a support layer under the first reflective layer, the sub-mount having a top most surface; and a sub-mount under the support layer, wherein the support layer is disposed between the bottom most surface of the first reflective layer and the sub-mount, wherein the top most surface of the support layer is disposed under the bottom most surface of the first reflective layer.
