Zusammenfassung:Disclosed is an organic light-emitting diode and an organic light-emitting device including the organic light-emitting diode. The organic light-emitting diode includes a cathode electrode; an anode electrode; a first emitting material layer including a first host and a first delayed fluorescent material, which is between the cathode electrode and the anode electrode; and a second emitting material layer having a second delayed fluorescent material and a first fluorescent or phosphorescent material, between the cathode electrode and the anode electrode. The organic light-emitting diode has enhanced luminous efficiency and color continuity.
