摘要：
An organic EL element includes a first electrode, a first luminescent layer, a second luminescent layer, a third luminescent layer, and a second electrode, in this order. The second luminescent layer is in contact with the first luminescent layer and the third luminescent layer. The first luminescent layer contains a red dopant and a first host material. The second luminescent layer contains a blue dopant and a second host material, and the third luminescent layer contains a green dopant and the second host material. The second host material is different from the first host material.
