    Abstract: To improve peelability, yield in a peeling step, and yield in manufacturing a flexible device. A peeling method is employed which includes a first step of forming a peeling layer containing tungsten over a support substrate; a second step of forming, over the peeling layer, a layer to be peeled formed of a stack including a first layer containing silicon oxynitride and a second layer containing silicon nitride in this order and forming an oxide layer containing tungsten oxide between the peeling layer and the layer to be peeled; a third step of forming a compound containing tungsten and nitrogen in the oxide layer by heat treatment; and a fourth step of peeling the peeling layer from the layer to be peeled at the oxide layer.

    Abstract: A highly reliable light-emitting device is provided. Damage to an element due to externally applied physical power is suppressed. Alternatively, in a process of pressure-bonding of an FPC, damage to a resin and a wiring which are in contact with a flexible substrate due to heat is suppressed. A neutral plane at which stress-strain is not generated when a flexible light-emitting device including an organic EL element is deformed, is positioned in the vicinity of a transistor and the organic EL element. Alternatively, the hardness of the outermost surface of a light-emitting device is high. Alternatively, a substrate having a coefficient of thermal expansion of 10 ppm/K or lower is used as a substrate that overlaps with a terminal portion connected to an FPC.

    Abstract: A semiconductor device including a large display portion with improved portability is provided. The display device includes a first display panel, a second display panel, and an adhesive layer. The area of the second display panel is larger than the area of the first display panel. The first display panel includes a first substrate, a second substrate, and a reflective liquid crystal element and a first transistor each positioned between the first substrate and the second substrate. The second display panel includes a first resin layer having flexibility, a second resin layer having flexibility, and a light-emitting element and a second transistor each positioned between the first resin layer and the second resin layer. The liquid crystal element has a function of reflecting light toward the second substrate side. The light-emitting element has a function of emitting light toward the second resin layer side. The first substrate and part of the second resin layer are bonded to each other with the adhesive layer.

    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.
