Abstract: An organic light emitting element includes a first electrode; a first organic layer on the first electrode; a second organic layer on the first organic layer; a second electrode on the second organic layer; and a mixed layer between the first organic layer and the second organic layer. A gap between a highest occupied molecular orbital (HOMO) energy level of the first organic layer and a lowest unoccupied molecular orbital (LUMO) energy level of the second organic layer may be in a range from about 1.35 eV to about 1.70 eV. The mixed layer may emit light having a wavelength in a range from about 740 nm to about 950 nm by exciplex.
