Abstract

According to a lighting apparatus using an organic light-emitting diode and a manufacturing method thereof of the present disclosure, a current imbalance due to a short circuit is controlled using a transparent high-resistance conductive film as a positive electrode instead of indium tin oxide (ITO), and a decrease in luminance is prevented by decreasing resistance of a positive electrode of an emission region through a post treatment. According to the present disclosure, it is possible to solve the problem of lighting malfunction of an entire panel, caused by a short circuit due to a foreign substance, even without reducing an aperture ratio, and concurrently, it is possible to secure normal luminance as resistance of an emission region is decreased.
