<P>PROBLEM TO BE SOLVED: To provide a high-efficiency and durable organic electroluminescent element having a low drive voltage, and to provide a compound useful for the organic electroluminescent element. <P>SOLUTION: The organic electroluminescent element has on a substrate a pair of electrodes comprising a positive electrode and a negative electrode and, between the electrodes, one or more organic layers including a light-emitting layer. The light-emitting layer contains at least one phosphorescent material. Moreover, the organic electroluminescent element contains, in at least one of the one or more organic layers, a specific compound having a dibenzothiophene or dibenzofuran structure and a phenanthrene structure. Also disclosed is the specific compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
