ABSTRACT:
An organic light-emitting device is provided which has an optical output with a high efficiency, a high luminance and a long life and which includes a pair of electrodes including an anode and a cathode, and at least one layer comprising an organic compound provided between the pair of electrodes, wherein at least one layer having a light-emitting region of the at least one layer comprising the organic compound comprises a first compound represented by the general formula (1):and a second compound having a bandgap larger than a bandgap of the first compound.
