Abstract: A light-emitting element with high heat resistance and high emission efficiency is provided. A novel heterocyclic compound that can be used in such a light-emitting element is provided. One embodiment of the present invention is a light-emitting element which includes, between a pair of electrodes, a layer containing a first organic compound, a second organic compound, and a light-emitting substance; the first organic compound includes one pyrimidine ring and one ring with a hole-transport skeleton; the second organic compound is an aromatic amine; and the light-emitting substance converts triplet excitation energy into light. A combination of the first organic compound, which includes the one pyrimidine ring and the one ring with the hole-transport skeleton, and the second organic compound, which is the aromatic amine, forms an exciplex.
