Patent ID: 8647164

Claim:
A method of producing an organic electroluminescent element comprising a laminated body incorporating an anode substrate, an anode, at least one non-light emitting organic layer A exhibiting positive hole transportability, at least one light emitting organic layer B, at least one non-light emitting organic layer C exhibiting electron transportability, a cathode, and a cathode substrate in the sequence set forth, the method comprising: laminating, on the anode substrate, the anode and the organic layer A in that order to form a partially laminated body; laminating, on the cathode substrate, the cathode and the organic layer C in that order to form a partially laminated body; forming the organic layer B on a temporary support; superposing the organic layer B side on the temporary support with the organic layer side of the partially laminated body on the anode substrate or the organic layer side of the partially laminated body on the cathode substrate, followed by subjecting to a heat treatment or a pressure treatment so as to transfer the organic layer B onto the organic layer side of the partially laminated body on the anode substrate or onto the organic layer side of the partially laminated body on the cathode substrate; superposing the organic layer B side of the substrate to which the organic layer B has been transferred with the organic layer side of the partially laminated body on another substrate to which the organic layer B has not been transferred, followed by subjecting to a heat treatment or a pressure treatment so as to form the laminated body; and sealing an entire periphery of the side of the laminated body with an adhesive.
