ABSTRACT:
There is provided an organic light-emitting element comprising at least one light-emitting layer between a pair of electrodes formed on a substrate and at least two or more light emission center materials included in the light-emitting layer, and that the at least one or more light emission center materials include a phosphorescent light-emitting material, and an excitation lifetime of the light emission center material that emits light having a shortest wavelength is shorter than an excitation lifetime of the other light emission center material, whereby a high-efficiency organic light-emitting element without decreasing a color purity of white light emission can be obtained.
