Abstract
A lighting apparatus using an organic light emitting diode and a method of fabricating the same according to the present disclosure is configured such that a contact electrode is formed using laser ablation and printing after an organic light emitting material, a conductive layer for a cathode and a passivation layer are deposited on an entire surface of a substrate, and then encapsulated with a metal film. The present disclosure simplifies a fabricating process of the lighting apparatus by virtue of a non-use of an open mask (metal mask) as a sophisticated apparatus, and particularly, can be effectively applied to a roll-producing process. Also, the present disclosure can provide an effect of improving reliability by preventing moisture permeation in a manner of covering an exposed contact portion with a protection film such as a barrier tape.
