摘要：
Herein disclosed are organic thin film EL element having layer structures each of which comprises at least one organic thin film sandwiched between two electrodes, at least one of which is a metal thin film or one of which is a metal thin film and the other of which is a transparent conductive inorganic thin film, and an optional thin film of an inorganic semiconductor positioned between the transparent conductive thin film and the organic thin film, wherein an interfacial layer is fromed between the organic thin film and the metal thin film adjacent to the organic thin film by treating the organic thin film and/or the metal thin film with an organic phosphorus atom-containing compound; and/or wherein an interfacial layer is formed between the organic thin film and the inorganic thin film adjacent to the inorganic thin film by treating the organic thin film and/or the inorganic thin film with a silane-coupling agent. In the EL element, the metal thin film formed on the organic thin film has low unevenness, the metal thin film is strongly adhered to the organic thin film.
