Abstract: An electron transport composition includes a metal oxide and a photoacid generator, wherein the photoacid generator has at least one of a halogenated triazine-based compound or an oxime sulfonate-based compound. When the electron transport composition is applied to a light-emitting element, the light-emitting element may exhibit improved luminous efficiency characteristics and element lifespan characteristics.
