Organic light emitting diode lighting apparatus

Abstract

An organic light emitting diode (OLED) lighting apparatus includes a substrate including a plurality of emission areas and a plurality of non-emission areas surrounding edges of the plurality of emission areas, an overcoat layer disposed on the substrate and having a first non-flat top surface in at least one of the emission areas and a second non-flat top surface in at least one of the non-emission area, an auxiliary electrode disposed on the second non-flat top surface and including a reflective material, a first electrode disposed on the first non-flat top surface in at least one of the emission areas and disposed on the auxiliary electrode in the non-emission areas, an organic emitting layer on the first electrode, and a second electrode on the organic emitting layer, wherein the auxiliary electrode and the first electrode are in electrical contact with each other.
