ABSTRACT:
Provided is an organic electroluminescent device having a high-efficiency optical output with high luminance and long life, which includes at least: a pair of electrodes comprising an anode and a cathode; and one or more organic-compound-containing layers sandwiched between the pair of electrodes, and in which among the organic-compound-containing layers, at least one layer having a light-emitting region contains a first compound represented by the following general formula [1] and a second compound having a band gap larger than a band gap of the first compound.
