As illustrated in FIG. 18, the light-emitting element 86R includes the oxide layer (the HTL) 124a serving as a hole-transport layer and the oxide layer 124b. The oxide layers 124a and 124b are provided between the first electrode 22 and the light-emitting layer 24c of the first wavelength range, and stacked one another from toward the first electrode 22. The light-emitting element 86R also includes the oxide layer (the ETL) 74a serving as an electron-transport layer and the oxide layer 74b. The oxide layers 74a and 74b are provided between the second electrode 25 and the light-emitting layer 24c of the first wavelength range, and stacked one another from toward the second electrode 25.
As the oxide layer (the HTL) 124a and the oxide layer 124b according to this embodiment, the oxide layer (the HTL) 124a and the oxide layer 124b according to the first to fourth embodiments are applicable.
Moreover, as the oxide layer (the ETL) 74a and the oxide layer 74b according to this embodiment, the oxide layer (the ETL) 74a and the oxide layer 74b according to the fifth to eighth embodiments are applicable.
