Abstract: A light-emitting device includes at least one light-emitting element including a first electrode and a second electrode facing each other, and a light-emitting layer provided between the first electrode and the second electrode. At least one of the light-emitting elements includes a plurality of carrier transport layers and at least one insulating layer, both being layered between the first electrode and the light-emitting layer. The insulating layer is provided at least partially between at least one carrier transport layer among the plurality of carrier transport layers and at least another carrier transport layer overlapping the at least one carrier transport layer.
