A light emitting device having a transparent substrate, a light emitting stack, and a transparent adhesive layer is provided. The light emitting stack is disposed above the transparent substrate and comprises a diffusing surface. The transparent adhesive layer is disposed between the transparent substrate and the diffusing surface of the light emitting stack; an index of refraction of the light emitting stack is different from that of the transparent adhesive layer.
