    Abstract: Provided is a novel substance that can be used in an element capable of emitting phosphorescence, a novel substance that contributes to high emission efficiency, or a novel substance that contributes to light emission with high color purity. A light-emitting element includes a pair of electrodes and an EL layer between the pair of electrodes. The EL layer includes a substance including a carbazole skeleton. The substance is bonded to a substituted or unsubstituted first arylene group through a nitrogen atom included in the carbazole skeleton. The first arylene group is bonded to a substituted or unsubstituted benzofuropyridyl group or a substituted or unsubstituted benzothienopyridyl group. The first arylene group includes 1 to 5 substituted or unsubstituted second arylene groups which are bonded to one another. The EL layer may further include a layer including an emission center substance, specifically an iridium compound.

    Abstract: A light-emitting element having low driving voltage and high emission efficiency is provided. In the light-emitting element, a combination of a guest material and a host material forms an exciplex. The guest material is capable of converting triplet excitation energy into light emission. Light emission from the light-emitting layer includes light emission from the guest material and light emission from the exciplex. The percentage of the light emission from the exciplex to the light emission from the light-emitting layer is greater than 0 percent and less than or equal to 60 percent. The energy after subtracting the energy of light emission from the exciplex from the energy of light emission from the guest material is greater than 0 eV and less than or equal to 0.23 eV.
