    Abstract: A light-emitting element includes a first electrode; a second electrode facing the first electrode; a light-emitting layer provided between the first electrode and the second electrode; a first charge transport layer provided between the first electrode and the light-emitting layer, and a middle layer provided between the first charge transport layer and the light-emitting layer. The middle layer contains at least one first component selected from SiO2, SiO, a metal oxide, and a metal fluoride.
