The invention discloses an organic electroluminescent device. A light-emitting layer comprises a host material and a guest material. The host material is an exciplex formed by an electron donor material and an electron acceptor material, and the guest material is a thermally activated delayed fluorescent material. The singlet-state energy level of the host material is lower than the singlet-stateenergy level of the guest material. Since the singlet-state energy level of the exciplex as the host material in the light-emitting layer is lower than the singlet-state energy level of the thermallyactivated delayed fluorescent material, the generation of high-energy excitons is prevented, and molecular bond breakage due to high excitation energy is effectively suppressed. The singlet-state energy level of the exciplex is low, which is beneficial to reduce the excitation energy of the excitons in the device, and suppress the triplet state-triplet state annihilation, the triplet state-polaronquenching and the singlet state-triplet annihilation phenomena in the device, thereby reducing the efficiency roll-off of the device and prolonging the service life of the device.
