    Abstract: A light-emitting device in which different electrodes in a work function are used in a first light-emitting element and a second light-emitting element are provided. A light-emitting device includes a first light-emitting element and a second light-emitting element. The first light-emitting element includes a first electrode, an EL layer, and a second electrode in this order. The second light-emitting element includes a third electrode, the EL layer, and the second electrode in this order. The EL layer includes a first light-emitting layer, a layer, and a second light-emitting layer in this order. The structure of the first light-emitting layer is different from the structure of the second light-emitting layer. The first light-emitting element and the second light-emitting element are different in a carrier-injection property.
