Claim Text:
1. A method of manufacturing an organic light-emitting device, the method comprising: providing a graphene donor unit, wherein the graphene donor unit comprises a graphene layer, a release layer, and an elastic stamp layer which are sequentially stacked; providing a device unit, wherein the device unit comprises a substrate, a lower electrode, and an organic part which are sequentially stacked; contacting the graphene layer of the graphene donor unit with the organic part; and removing the release layer and the elastic stamp layer, wherein: the providing of the graphene donor unit comprises patterning the graphene layer such that, when taken from a sectional view, the graphene layer is separated into a plurality of graphene layer parts spaced apart from each other; the graphene layer comes in contact with the organic part, such that a top surface of the organic part has a plurality of first regions covered by the graphene layer and a second region without being covered by the graphene layer between the plurality of first regions; and the providing of the graphene donor unit includes forming the graphite layer on a mother substrate, then the patterning of the graphene layer, then disposing the patterned graphene layer on the release layer and the elastic stamp layer, and then removing the mother substrate from the graphite layer.
