Abstract
An embodiment of present disclosure discloses a light-emitting device which includes a light-emitting unit, a transparent covering structure, a first reflective structure, a second reflective structure, and a wavelength conversion structure. The light-emitting unit includes a light-emitting surface, a bottom surface opposite to the light-emitting surface, a side surface, a first conductive electrode, and a second conductive electrode. The first conductive electrode and the second conductive electrode are located on the bottom surface. The transparent covering structure covers the light-emitting surface and the side surface. The first reflective structure surrounds the transparent covering structure. The second reflective structure is disposed under the first reflective structure and surrounds the first conductive electrode and the second conductive electrode. The wavelength conversion structure is disposed on the first reflective structure and the transparent covering structure.
