Abstract:
Provided is an organic electroluminescent element containing an anode, a cathode, and an organic functional layer containing one or a plurality of light-emitting layers, the organic functional layer being interposed between the anode and the cathode, wherein at least one of the light-emitting layers contains a compound having two condensed aromatic rings bonded to each other with a linking group; and the condensed aromatic rings form a π-π stacking structure in the molecule.
