PROBLEM TO BE SOLVED: To aim at lowering drive voltage by making a positive hole barrier from a positive electrode to an organic layer, small. SOLUTION: In an organic electric field light emitting device, which has a luminescence layer sandwiched by the positive electrode and a negative electrode on a substrate, a mono-molecule layer constituted from specific structure on a surface by a side of the luminescence layer of the positive electrode, is prepared. Or the surface of the side of the luminescence layer of the positive electrode is processed with a specific compound. |
