<p>PROBLEM TO BE SOLVED: To provide an electroluminescent element excellent in heat resistance and durability by restraining thermal deterioration of an organic electroluminescent element. SOLUTION: With the electroluminescent element composed of consisting of a positive and a negative electrodes, and organic compounds of one or a plurality of layers pinched between them, a conductive thin film formed of an oligoaniline derivative as represented in a formula (1), an electron-accepting dopant and salt as a carrier transport sub-layer between the positive electrode and the organic layer. In the formula, R1, R2 and R3 denote, each independently, non-substitute or substitute univalent carbon hydride group, or organooxy group, A and B each independently bivalent group as represented in formula (2) or (3), and R4 to R11 denote, each independently, hydrogen atom, a hydroxyl group, a non-substitute or substitute univalent carbon hydride group or organooxy group, acyl group, or sulfonic group. 'm' and 'n' denote, each independently, an integer of 1 or more, and satisfy m+n<=20.</p> |
