ABSTRACT:
The present invention provides a patterning method of an organic EL device that can easily and efficiently be performed with high definition, and that can control a contrast by a luminous brightness.In an organic EL device having an organic layer, including an organic luminescent material, formed between a pair of counter electrodes, ultraviolet ray is irradiated to the organic layer, and the amount of irradiation is changed to form an emission pattern having a contrast caused by a luminous brightness corresponding to the amount of the irradiation of the ultraviolet ray.
