ABSTRACT:
There are provided a condensed ring aromatic compound and an organic light-emitting device having an optical output with high efficiency and high luminance, and durability. An organic light-emitting device including: a pair of electrodes comprising an anode and a cathode of which at least one is transparent or translucent; and an organic compound layer disposed between the pair of electrodes, wherein the organic compound layer contains the condensed ring aromatic compound represented by the following formula [1].In the formula, X1to X16each independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, and each may be the same or different; adjacent groups combine with each other to form at least one ring in the group selected from X4to X7; and adjacent groups combine with each other to form at least one ring in the group selected from X12to X15.
