<p>The purpose of the invention is to provide an organic electroluminescent element of superior luminescent element life and drive voltage. The organic electroluminescent element is produced using a benzo[c]carbazole compound represented by formula (1) as the electron transport material. (In formula (1), R is an aryl or heteroaryl, either A or A' is a group selected from groups represented by formulas (A-1) - (A-4) and the other is a C6-18 aryl.)</p> |
