Abstract
A light emitting device includes a light emitting unit, a light transmissive layer and an encapsulant. The light emitting unit includes a substrate, an epitaxial structure layer disposed on the substrate, and a first electrode and a second electrode disposed on the same side of the epitaxial structure layer, respectively. The light emitting unit is disposed on the light transmissive layer and at least a part of the first electrode and a part of the second electrode are exposed by the light transmissive layer. The encapsulant encapsulates the light emitting unit and at least exposes a part of the first electrode and a part of the second electrode. Each of the first electrode and the second electrode extends outward from the epitaxial structure layer, and covers at least a part of an upper surface of the encapsulant, respectively.
