Abstract: A film having a plurality of lighting devices thereon is transferred between a film supplying roll and a film collecting roll, and an organic light emitting layer and a second electrode are formed on the film being transferred from a deposition unit. An aging unit is provided on a rear end of the deposition unit, and applies an aging voltage to the film transferred after the organic light emitting layer is deposited by the deposition unit, thereby aging the organic light emitting layer.

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.
