Abstract
A lighting apparatus including organic light-emitting diodes comprises an anode disposed in an emission area of a substrate; first and second pad electrodes disposed on an outer side of the emission area of the substrate; a short-circuit reduction pattern surrounding an emission zone of each of pixels and formed by removing a part of the anode; a passivation layer comprising the short-circuit reduction pattern and disposed on the anode; an organic layer and a cathode disposed on the passivation layer in the emission area of the substrate; and a metal film disposed in the emission area of the substrate, wherein the short-circuit reduction pattern has a gradually-reducing resistance with an increased distance between the pixels and the first and second pad electrodes.
