<p><P>PROBLEM TO BE SOLVED: To provide an organic electroluminescent element in which emission lifetime can be improved by preventing corrosion of an electrode or a luminous layer arranged contiguously to a hole injection layer or spaced apart therefrom, and lowering of emission efficiency can be minimized. <P>SOLUTION: An organic electroluminescent element includes a light-emitting part 14 where at least a hole injection layer 14a and a luminous layer 14b are provided between a pair of electrodes (anode 12, cathode 13). The hole injection layer 14a consists of a polymer semiconductor coat formed of a polymer semiconductor paint. The polymer semiconductor paint contains aπconjugate polymer semiconductor, polyanion, and a neutralizer consisting of at least one of triethanolamine and tri-isopropanol amine. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
