Abstract:
1. A light emitting device, comprising: a substrate; a light emitting structure; a first electrode on the light emitting structure; a contact layer between the substrate and the light emitting structure; a metal layer between the substrate and the light emitting structure; a reflective layer between the substrate and the light emitting structure; an adhesive layer between the substrate and the light emitting structure; wherein the light emitting structure comprise a first region and a second region, wherein the metal layer and the reflective layer are disposed under the light emitting structure at the first region of the light emitting structure, wherein the contact layer contacts with the light emitting structure at the second region of the light emitting structure, wherein a lateral width of the second region of the light emitting structure is smaller than a lateral width of the first region of the light emitting structure, wherein the metal layer and the reflective layer vertically overlaps each other, wherein a material of the contact layer is different from a material of the reflective layer, and wherein at least one of the reflective layer or the metal layer does not vertically overlap the first electrode layer.
