摘要： In an organic light-emitting element including a first electrode, a second electrode, and a light-emitting layer placed between the first electrode and the second electrode, the light-emitting layer includes a host material, a first emitter, and a second emitter, the emission peak wavelength of the first emitter is longer than the emission peak wavelength of the second emitter, and an aromatic heterocyclic ligand or an auxiliary ligand of the first emitter include an electron withdrawing group. Accordingly, an organic light-emitting element can be provided in which the HOMO value of a specific luminescent dopant is closer to the HOMO value of another luminescent dopant.
