PROBLEM TO BE SOLVED: To provide a method for manufacturing a stack type organic electroluminescent element, by which a long life can be achieved while a manufacturing process is easy.SOLUTION: A method for manufacturing a stack type organic electroluminescent element comprises the steps of: preparing a first laminate 100 having, on the side of one face of a first substrate 10, at least one light-emitting unit 13 including a positive electrode 11 and a light-emitting layer 12; preparing a second laminate 200 having, on the side of one face of a second substrate 20, at least one light-emitting unit 23 including a negative electrode 21 and a light-emitting layer 22; forming, by using ink having a particular composition, a precursory coating of a charge-generation layer 14(M) on a surface of the first laminate on the side of the light-emitting unit and/or a precursory coating of a charge-generation layer 24(N) on a surface of the second laminate on the side of the light-emitting unit; and sticking the light-emitting unit side of the first laminate and the second laminate and the light-emitting unit side of the second laminate to each other through the charge-generation layer precursory coating with each or the one charge-generation layer precursory coating formed in position to form each or the one charge-generation layer.SELECTED DRAWING: Figure 4 |
