Patent ID: 7485376

Claim:
An organic electroluminescent element comprising a light emission layer containing a phosphorescent compound and a hole transporting layer adjacent thereto containing a hole transporting material, wherein the hole transporting material has a 0-0 band of the phosphorescence spectra of from 300 to 450 nm and has a molecular weight of not less than 550, and is a triarylamine compound represented by the following Formula 4-1 or 4-2: wherein Ar 801 through Ar 803 independently represent a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group; and R 801 through R 827 independently represent a hydrogen atom or a substituent, provided that at least one of R 801 and R 802 is a substituent, at least one of R 803 and R 804 is a substituent, at least one of R 805 and R 806 is a substituent, at least one of R 807 through R 810 is a substituent, at least one of R 811 through R 814 is a substituent, and at least one of R 815 through R 818 is a substituent.
