<p><P>PROBLEM TO BE SOLVED: To provide an organic EL element continuously keeping high luminous efficiency over a long time even in a high-temperature condition. <P>SOLUTION: In this organic electroluminescent element including a pair of an anode and a cathode, and an organic luminescent function layer sandwiched between the anode and the cathode, the organic luminescent function layer is formed as a multilayered structure of an organic material; and at least either of a tribiphenylamine derivative having an aryl group up to a tricyclic one that may have a substituent and a tris(para-naphthyl)triphenylamine derivative having an aryl group up to a tricyclic one is included in the multilayered structure, preferably in a hole transport layer. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
