An organic electroluminescent device includes: a pair of electrodes including a positive electrode and a negative electrode, at least one of the electrodes being transparent or semi-transparent; and an organic compound layer including one or more layers interposed between the pair of electrodes, at least one layer included in the organic compound layer containing one or more compounds represented by the following formula (I):
in formula (I), R
1
s each independently representing a linear alkyl, linear alkoxy, branched alkyl, or branched alkoxy group having from 3 to 20 carbon atoms; and R
2
s each independently representing a hydrogen atom, a linear alkyl group having from 1 to 20 carbon atoms, a linear alkoxy group having from 1 to 20 carbon atoms, a branched alkyl group having from 3 to 20 carbon atoms, or a branched alkoxy group having from 3 to 20 carbon atoms.
