Patent ID: 7455792

Claim:
An organic electroluminescence element having a conductive thin film formed from a conductive varnish comprising an organic conductive material which comprises a salt formed by an oligoaniline derivative represented by the formula (1) in which quinoimine as an oxidant formed at the time of synthesis of the oligoaniline derivative is reduced by a reducing agent, and an electron accepting dopant, where R 1 and R 2 independently denote a hydrogen atom, unsubstituted or substituted monovalent hydrocarbon group, organoxy group, or acyl group, R 3 denotes a phenyl group; A and B independently denote a divalent group represented by the formula (2) or (3) below; where, R 4 to R 11 independently denote a hydrogen atom, hydroxyl group, unsubstituted or substituted monovalent hydrocarbon group, organoxy group, acyl group, or sulfonic group; and m and n independently denote a positive number equal to or larger than 1 such that m+n≦20, and wherein the organic conductive material of the conductive varnish is in an amount of 1 to 80wt %.
