<P>PROBLEM TO BE SOLVED: To provide an aging method of an organic EL device, the method being able to process the aging of the device in a roll-to-roll manner, having a high aging processing capacity, and obtaining an organic EL device with stable emission luminance. <P>SOLUTION: An aging method of an organic EL device performs aging of an organic EL device group. The organic EL device group consists of: on a long flexible band-like substrate, a plurality of organic EL structures having a first electrode comprising at least extraction electrode parts, an organic functional layer including a luminescent layer, and a second electrode comprising extraction electrode parts; and a sealing member covering the organic EL structures. In the method, the plurality of extraction electrode parts of the first electrode are connected using a first conductive power supply member; the plurality of extraction electrode parts of the second electrode are connected using a second conductive power supply member; and the first conductive power supply member and the second conductive power supply member are electrified with the flexible band-like substrate wound in a roll shape, thereby causing the organic EL device to emit light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
