Abstract
An organic adhesive light-emitting device with a vertical structure is provided. The organic adhesive light-emitting device comprises a conductive substrate with a concavo-convex upper surface; a first metal layer formed on the concavo-convex upper surface of the conductive substrate; an organic adhesive material formed over the first metal layer; a second metal layer formed over the organic adhesive material, wherein all or part of the first metal layer over the concavo-convex upper surface is in ohmic contact with the second metal layer through the organic adhesive material; a reflective layer formed over the second metal layer; and a light-emitting stack layer formed over the second metal layer. The process for manufacturing the present invention organic adhesive light-emitting device is less complex than that for manufacturing prior art diodes.
