Abstract:
1. A method for producing an organic electroluminescent device by using a transfer material, said transfer material comprising a temporary support, an electroluminescent element layer, and a peeling layer between said temporary support and said electroluminescent element layer, said method comprising the steps of: contacting the electroluminescent layer side of said transfer material with an electrode layer side of a substrate, wherein said electrode layer is partially or wholly transparent or opaque; and transferring said at least one electroluminescent element layer to said electrode layer side of said substrate with at least one heating means and pressing means, wherein a maximum surface roughness Rmax (according to JIS B 0601-1982) of said peeling layer is not less than 0 and not more than 50, assuming that the thickness of said electroluminescent element layer is 100.
