Abstract

There is provided a material for an anode buffer lay which permits the use of an organic solvent as a solvent an anode buffer layer-forming solution, and is capable forming an anode buffer layer that does not dissolve even win coated with a luminescent layer-forming material solution containing an organic solvent as a solvent, and which is capable of producing an organic EL element having high electrical power efficiency and long life.
