Abstract
Provided is a light emitting device, which includes a second conductive type semiconductor layer, an active layer, a first conductive type semiconductor layer, and a intermediate refraction layer. The active layer is disposed on the second conductive type semiconductor layer. The first conductive type semiconductor layer is disposed on the active layer. The intermediate refraction layer is disposed on the first conductive type semiconductor layer. The intermediate refraction layer has a refractivity that is smaller than that of the first conductive type semiconductor layer and is greater than that of air.
