Abstract: A light emitting device and a manufacturing method thereof are provided. The light emitting device includes a light emitting unit, a fluorescent layer, a reflective layer, and a light-absorbing layer. The light emitting unit has a top surface, a bottom surface opposite to the top surface, and a side surface located between the top surface and the bottom surface. The light emitting unit includes an electrode disposed at the bottom surface. The fluorescent layer is disposed on the top surface of the light emitting unit. The reflective layer covers the side surface of the light emitting unit. The light-absorbing layer covers the reflective layer, so that the reflective layer is located between the side surface of the light emitting unit and the light-absorbing layer.

Abstract: A light emitting device including a light emitting unit, two electrodes, a reflective member, and a light transmissive member is provided. The two electrodes are disposed on one side of the light emitting unit, and electrically connected to the light emitting unit. The reflective member is disposed on the other side of the light emitting unit, and has at least one reflective surface. The light transmissive member is disposed between the reflective member and the light emitting unit, and covers a part of the light emitting unit. A lateral surface of the light transmissive member is served as a light emitting surface of the light emitting device. A manufacturing method of a light emitting device is also provided.
