A light emitting element has an organic layer that sequentially includes a first emission layer and a second emission layer, a first reflection interface, and a second reflection interface, wherein, if the optical distance between the first reflection interface and the emission center of a first emission layer is L11, the optical distance between the first reflection interface and the emission center of a second emission layer is L21, the optical distance between the emission center of the first emission layer and the second reflection interface is L12, the optical distance between the emission center of the second emission layer and the second reflection interface is L22, a central wavelength of an emission spectrum of the first emission layer is λ1, and a central wavelength of an emission spectrum of the second emission layer is λ2, the optical distances L11, L21, L12 and L22 satisfy predetermined expressions. |
