To provide a material for an electroluminescence element of which a buffer layer can be formed without using water as a solvent unlike a conventional polymer material used in a buffer layer, and an electroluminescence element using the same. According to the present invention, in an electroluminescence (EL) element including a first electrode ( 101 ), a buffer layer ( 102 ), an electroluminescence (EL) film ( 103 ), and a second electrode ( 104 ) (as shown in FIG. 1 A), a conductive material is used as the buffer layer ( 102 ) formed on the first electrode ( 101 ). The conductive material includes: a polymer compound (so-called conjugate polymer) soluble in an organic solvent, which has a conjugate on a main or side chain thereof; and a compound soluble in an organic solvent, which has acceptor or donor properties for the polymer compound. |
