Abstract:
1. A method of producing an organic electroluminescent element comprising a substrate having thereon: a first electrode; an organic compound layer; a second electrode; and a sealing layer, the method comprising the steps of: supplying the substrate from a first roll core upon which the substrate had been wound; supplying a masking member from a second roll core upon which the masking member had been wound; laminating the masking member onto a region of the substrate on which the organic compound layer is prevented from forming, provided that the masking member has an adhesion force of from 4.1 to 6.5 N/25 mm; forming the organic compound layer on the substrate; and separating the masking member from the masked substrate on which the first electrode and organic compound layer have been formed.
