    Abstract: An organic light-emitting device is provided That includes: a first electrode; a second electrode facing the first electrode; m number of emission units disposed between the first electrode and the second electrode, the emission units each including at least one emission layer. m−1 charge generation layers are disposed between two adjacent emission units and each includes an n-type charge generation layer and a p-type charge generation layer. Maximum emission wavelengths of light emitted by two emission units may be different. At least one of the emission units, at least one of the charge generation layers, or any combination thereof may each include a first compound, which may be represented by Formula 1:
