Abstract: The present disclosure relates to the field of display technologies, and particularly discloses an organic electroluminescent device. The organic electroluminescent device has a first electrode, a second electrode, and an organic functional layer. The organic functional layer comprises a light-emitting layer. The light-emitting layer comprises at least a host material and a guest material. The host material comprises an exciplex composed of a donor molecule and a receptor molecule, wherein the donor molecule and/or the receptor molecule contains a large steric hindrance substituent group X for increasing an inter-molecular distance between the donor molecule and the receptor molecule, which enables to enhance Foster energy transfer to the guest material molecule, improve device efficiency, inhibit Triplet-Polaron Annihilate Annihilation (TPA), and prolong the device lifetime.
