    Abstract: To provide a light-emitting element with high emission efficiency or long lifetime, in which the use amount of a phosphorescent compound is small. To provide a light-emitting element including a light-emitting layer between a pair of electrodes, wherein the light-emitting layer includes a phosphorescent compound, a first organic compound, and a second organic compound, and the combination of the first organic compound and the second organic compound forms an exciplex. The light-emitting element transfers energy by utilizing the overlap between the emission spectrum of the exciplex and the absorption spectrum of the phosphorescent compound and thus has high energy transfer efficiency, even when the concentration of the phosphorescent compound is low.

    Abstract: An object is to provide a light-emitting element which includes an exciplex being used as an energy donor capable of efficiently transferring energy to a substance exhibiting thermally activated delayed fluorescence. The exciplex comprises two kinds of substances and its singlet and triplet excited states are close to each other. Thus, by making light emission of the exciplex overlap with an absorption band on the longest wavelength side which corresponds to absorption by the substance exhibiting thermally activated delayed fluorescence, i.e., an energy acceptor, in a singlet excited state, it becomes possible to achieve efficient energy transfer from a singlet excited state of the exciplex to a singlet excited state of the substance exhibiting thermally activated delayed fluorescence, and it also becomes possible to achieve efficient energy transfer from a triplet excited state of the exciplex to a triplet excited state of the substance exhibiting thermally activated delayed fluorescence.
