MATERIAL FOR ELECTROLUMINESCENT ELEMENT AND ELECTROLUMINESCENT ELEMENT USING THE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a material for an electroluminescent element and an electroluminescent element using the material capable of forming a buffer layer without using water as a solvent, as is different from a polymer system material used in a conventional buffer layer. SOLUTION: With the electroluminescent element provided with a first electrode 101, a buffer layer 102, an electroluminescent film 103 and a second electrode as shown in Figure (A), a conductive material including a polymer compound containing a conjugate in a main chain or a side chain (what is called a conjugate polymer) as a polymer system material soluble to an organic solvent and a compound soluble to an organic solvent and having either an acceptor property or a donor property against the above polymer compound is used as a material for forming the buffer layer 102 formed on the first electrode 101.
