Abstract: A display device with low power consumption is provided. Furthermore, a display device in which an image is displayed in a region that can be used in a folded state is provided. The conceived display device includes a display portion that can be opened and folded, a sensing portion that senses a folded state of the display portion, and an image processing portion that generates, when the display portion is in the folded state, an image in which a black image is displayed in part of the display portion.

Abstract: The thickness of a display device including a touch sensor is reduced. Alternatively, the thickness of a display device having high display quality is reduced. Alternatively, a method for manufacturing a display device with high mass productivity is provided. Alternatively, a display device having high reliability is provided. Stacked substrates in each of which a sufficiently thin substrate and a relatively thick support substrate are stacked are used as substrates. One surface of the thin substrate of one of the stacked substrates is provided with a layer including a touch sensor, and one surface of the thin substrate of the other stacked substrate is provided with a layer including a display element.

Abstract: A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.
