Abstract: A highly reliable display device or electronic appliance is provided. The display device or a light-emitting device includes a substrate; a light-emitting element including a first electrode, an EL layer, and a second electrode; an organic resin film in contact with the light-emitting element; and an oxide semiconductor film in contact with the light-emitting element and the organic resin film. The oxide semiconductor film is in contact with the first electrode or the second electrode included in the light-emitting element. The oxide semiconductor film is in contact with an exposed portion of the organic resin film, typically, a side surface of the organic resin film. The light-emitting element and the organic resin film are positioned between the substrate and the oxide semiconductor film.
