Abstract
A light emitting device includes a substrate, an electrode connection layer, an epitaxial structure and a plurality of pads. The substrate has an upper surface, a lower surface and a plurality of conductive through holes. The electrode connection layer is disposed on the upper surface of the substrate and has at least one first electrode, at least one second electrode and a connection layer which has at least one buffer region. The epitaxial structure is disposed on the electrode connection layer and electrically connected to the electrode connection layer. The pads are disposed on the lower surface of the substrate and connect with the conductive through holes.
Claims21
