Abstract

According to a lighting apparatus using an organic light emitting diode of the present disclosure and a manufacturing method thereof, a transparent high resistance conductive layer is used for an anode instead of ITO to control the concentrated current due to the short and the anode of the emission area lowers the resistance through the post-treatment to suppress the lowering of luminance. Further, the auxiliary electrode is formed of a transparent nanowire and the first protective layer above the auxiliary electrode is removed to be utilized as an emission area, so that the aperture ratio is drastically improved.
