Abstract: A light-emitting element includes a pair of electrodes, a first light-emitting unit, a second light-emitting unit, and a charge generation layer. The first light-emitting unit, between the pair of electrodes, and the first light-emitting unit, includes a first light-emitting layer. The second light-emitting unit, between the pair of electrodes, includes a second light-emitting layer. A first luminescent layer includes a first main body material, a second main body material, a first guest material, and a first auxiliary material, and the first main body material forms a first excimer complex with the second main body material. A first excited triplet state energy level of the first auxiliary material is lower than a first excited triplet state energy level of the first excimer complex, and the first excited triplet state energy level of the first auxiliary material is higher than that of the first guest material.
