Abstract
A light emitting device includes at least one light emitting and connecting unit that includes an epitaxial layer structure and a metallic connecting layer structure, and an insulating substrate that has a main substrate body and first and second contact members. The connecting layer structure interconnects the epitaxial layer structure and the main substrate body, and is completely plane at least right under the epitaxial layer structure. The contact members extend from a first surface to a second surface on the main substrate body, and are disposed outside an imaginary projection of the epitaxial layer structure on the main substrate body. The first contact member is electrically connected with the connecting layer structure. Alight emitting apparatus including the device is also disclosed.
