Abstract: A red light-emitting element includes an anode, a cathode, and a red light-emitting layer, the red light-emitting layer includes a compound including Sn (IV) and a chalcogen, a quantum dot, a first compound including Sn (II) and a chalcogen of the same element as the chalcogen, and a chalcogenium ion of the same element as the chalcogen, and a substance amount rate of Sn (II) to Sn (IV) is more than 0% and equal to or less than 50%.
