PROBLEM TO BE SOLVED: To provide an organic EL element which realizes cost reduction, and further to provide a manufacturing method thereof.SOLUTION: An organic EL element comprises: a substrate; a positive electrode provided on the substrate; a light-emitting layer; and a negative electrode. A mixture containing plural kinds of condensed polycyclic aromatic molecules is used as a material for the light-emitting layer. A manufacturing method of the organic EL element having at least the positive electrode, the light-emitting layer and the negative electrode on the substrate, comprises the steps of: forming either one of the positive electrode and the negative electrode on the substrate; forming the light-emitting layer on the positive electrode or the negative electrode; and forming the other one of the positive electrode and the negative electrode on the light-emitting layer. The mixture containing plural kinds of condensed polycyclic aromatic molecules is used as a material for the light-emitting layer. |
