Abstract
This disclosure discloses a light-emitting device. The light-emitting device includes a light-emitting stack with a first (top) surface, a bottom surface and at least one side surface connected to the first surface and the bottom surface, a light-reflective enclosure with a second (top) surface, a contact electrode formed on the bottom surface of the light-emitting layer, and a wavelength converting layer. Moreover, the light-reflective enclosure surrounds the side surface of the light-emitting stack and exposes to the first surface. The wavelength converting layer covers the first surface and the second surface. In addition, the second surface has a plurality of fine concave structures distributed on the second surface.
