Abstract:
A light-emitting element having high emission efficiency which includes a fluorescent material as a light-emitting substance is provided. A light-emitting element includes a pair of electrodes and an EL layer between the pair of electrodes. The EL layer includes a light-emitting layer. The light-emitting layer includes a host material and a guest material. The host material has a difference of more than 0 eV and less than or equal to 0.2 eV between a singlet excitation energy level and a triplet excitation energy level. The guest material is capable of emitting fluorescence. The triplet excitation energy level of the host material is higher than a triplet excitation energy level of the guest material.

Claim (Index 11):
A light-emitting element comprising:\n a pair of electrodes; and an electroluminescence layer between the pair of electrodes, wherein the electroluminescence layer comprises a light-emitting layer, wherein the light-emitting layer comprises a first organic compound, a second organic compound, and a third organic compound, wherein a combination of the first organic compound and the second organic compound is capable of constituting an exciplex, wherein the third organic compound is capable of emitting fluorescence, wherein light emitted from the light-emitting layer comprises light emitted from the guest material, wherein light emitted from the light-emitting layer comprises delayed fluorescence, and wherein the triplet excitation energy level of the exciplex is higher than a triplet excitation energy level of the third organic compound.
