Abstract
A lighting apparatus using an organic light emitting diode comprises a first anode and a second anode respectively disposed in an emission zone and a non-emission zone of an emission area defined at a substrate; a first insulating layer disposed on the second anode; an organic layer and a primary cathode disposed on the first anode; a secondary cathode disposed on the insulating layer and laterally connected to the primary cathode; and an encapsulating material disposed above the substrate, wherein the organic layer is disposed only between the primary cathode and the secondary cathode in the emission zone.
