| 摘要 |
Disclosed is a light emitting device (500) including a light emitting structure (200) including a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer; a substrate (100) over the light emitting structure; a first reflective layer (310) having a plurality of dielectric layers including a first dielectric layer (311) having a first refractive index over the substrate, and a second dielectric layer (312) having a second refractive index different from the first refractive index over the first dielectric layer; and a second reflective layer (320) over 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. |
