ORGANIC EL ELEMENT AND METHOD FOR MANUFACTURING ORGANIC EL ELEMENT

摘要

An organic EL element which comprises: a positive electrode; a light emitting layer that is arranged above the positive electrode; a first intermediate layer that is arranged on the light emitting layer; a second intermediate layer that is arranged on the first intermediate layer; a functional layer that is arranged on the second intermediate layer; and a negative electrode that is arranged above the functional layer. The first intermediate layer contains a fluoride of a first metal that is an alkali metal or an alkaline earth metal. The second intermediate layer contains a second metal that has a property of breaking the bond between the first metal and a fluorine atom in the fluoride of the first metal. The functional layer (21) has an electron transport property and/or an electron injection property. If D1 is the film thickness of the first intermediate layer and D2 is the film thickness of the second intermediate layer, D1 and D2 satisfy the relational expression 3 [%] ≤ D2/D1 ≤ 25 [%].
