PURPOSE:To provide an organic film EL element with less drift of luminous characteristic and less deterioration during element storage. CONSTITUTION:A metal layer forming an electron injection electrode is made in 2 layers or more, a metal layer 5 which is in contact with an organic film layer is formed out of a metal such as MgIn, and an outer metal layer 6 is formed out of Au, etc., with grater work function. By forming at least one layer of those metal layers by a spatter film formation method, adhesiveness with an organic luminous body film layer 4 is improved and drift of a luminous characteristic is decreased. |
