    摘要: Provided is an organic light-emitting device that can be driven at low voltage, that produces a light output with high efficiency and high luminance, and that can emit light with high color purity. An organic light-emitting device includes an anode, a cathode, a light-emitting layer disposed between the anode and the cathode, and an organic layer disposed between the anode and the light-emitting layer. The organic layer has a fused polycyclic compound represented by general formula (1): wherein R1 to R8 are each a hydrogen atom, a halogen atom, a cyano group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted polycyclic group and are each the same or different, and wherein R9 and R10 are substituted or unsubstituted aryl groups that are the same or different.
