Abstract
A light-emitting device including an epitaxial layer, a support layer, an insulating layer, a first electrode pad, and a second electrode pad is provided. The epitaxial layer includes a first type doped semiconductor layer, a light-emitting layer and a second type doped semiconductor layer, wherein the light-emitting layer is disposed on a partial area of the first type doped semiconductor layer and is between the first type doped semiconductor layer and the second type doped semiconductor layer. The support layer covers the second type doped semiconductor layer while the insulating layer covers the epitaxial layer and the support layer. The first and the second electrode pads are disposed over the insulating layer and electrically connected to the first and the second type doped semiconductor layers, respectively. The support layer extends from a first position below the first electrode pad to a second position below the second electrode pad.
