Abstract
A lighting apparatus using an organic light emitting diode according to the present disclosure is configured such that a substrate is planarized by forming an anti-scratch layer on a cathode electrode to fully cover the cathode electrode. The present disclosure having such configuration can uniformly maintain pressing pressure by virtue of the anti-scratch layer even while winding or unwinding the substrate for pulse aging, thereby preventing damages due to scratches or particles.
