1. A light-emitting device, comprising:
- a substrate;
a light-emitting stack above the substrate and having a first diffusing surface; and
a transparent connective layer between the substrate and the first diffusing surface;
wherein a surface of the transparent connective layer adjacent to the substrate is a flat surface.

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