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.

Abstract: According to the present disclosure, an organic light emitting material and a metal may be entirely deposited on a substrate without using an open mask to form an organic light emitting device, thereby facilitating application to a roll fabrication apparatus. A side surface of an organic light emitting layer may be exposed to the outside, but a step structure may be formed on an outer portion of the substrate, and the organic light emitting layer is disconnected between an outer region and a lighting region by the step of the step structure, thereby preventing moisture that penetrates into the organic light emitting layer in the outer region from being propagated to the organic light emitting layer in the lighting region.
