Abstract
Organic adhesive light-emitting device with ohmic metal bulge. The organic adhesive light-emitting device includes a conductive substrate, a light-emitting stack layer, a metal layer formed over the conductive substrate, a reflective layer formed over the light-emitting stack layer, and an organic adhesive layer having an ohmic metal bulge and an adhesive material around the ohmic metal bulge. The adhesive material bonds the metal layer and the reflective layer together, while the ohmic metal bulge forms ohmic contacts with the metal layer and the reflective layer. The configuration can simplify a light-emitting diode.
