Provided is a light-emitting element that has excellent external quantum efficiency. A light-emitting element that has a positive electrode, a negative electrode, a first light-emitting layer provided between the positive electrode and the negative electrode, and a second light-emitting layer provided between the positive electrode and the negative electrode; the first light-emitting layer being obtained by using a polymeric compound containing a structural unit that has a crosslinking group and a phosphorescent light-emitting structural unit, and the second light-emitting layer being obtained by using a composition that contains a non-phosphorescent light-emitting compound that has a heterocyclic structure and at least two phosphorescent light-emitting compounds.
