Patent ID: 7880182

Claim:
A light-emitting element array comprising: a conductive substrate; an adhesive layer disposed on the conductive substrate; a first epitaxial light-emitting stack layers disposed on the adhesive layer, the first epitaxial light-emitting stack layers comprising a first contact and an second contact, wherein the first contact and the second contact are disposed on the same side of the first epitaxial light-emitting stack layer; and a second epitaxial light-emitting stack layers disposed on the adhesive layer, the second epitaxial light-emitting stack layers comprising a third contact and an fourth contact, wherein the third contact and the fourth contact are disposed on the opposite side of the epitaxial light-emitting stack layer; wherein the first epitaxial light-emitting stack layers and the second epitaxial light-emitting stack layers are electrically connected in anti-parallel.
