摘要： 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. After the two stacked substrates are attached to each other so that the touch sensor and the display element face each other, the support substrate and the thin substrate of each stacked substrate are separated from each other.

摘要： A light-emitting device includes a strip-like high flexibility region and a strip-like low flexibility region arranged alternately in a direction. The high flexibility region includes a flexible light-emitting panel. The low flexibility region includes the light-emitting panel and a support panel having a lower flexibility than that of the light-emitting panel and overlapping with the light-emitting panel. It is preferable that the light-emitting panel include an external connection electrode and that a length in the direction of a low flexibility region A that overlaps with the external connection electrode be longer than a length in the direction of a low flexibility region B that is closest to the region A.

摘要： A novel foldable display device or an electronic device using the same, e.g., a portable information processor or a portable communication information device, is provided. A foldable display device of which a display panel can be folded n times (n≥1, and n is a natural number) at a curvature radius of greater than or equal to 1 mm and less than or equal to 100 mm is obtained. The display device can be miniaturized by being foldable. In addition, in the state where the flexible display panel is opened, display which is unbroken and continuous over a plurality of housings is possible. The plurality of housings can store a circuit, an electronic component, a battery and the like inside as appropriate, and the thickness of each housing can be small.

摘要： 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.

摘要： 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.

摘要： A display device including a peripheral circuit portion with high operation stability. The display device includes a first substrate and a second substrate. A first insulating layer is on a first plane of the first substrate, and a second insulating layer is on a first plane of the second substrate. An area of the first plane of the first substrate is the same as an area of the first plane of the second substrate. The first plane of the first substrate and the first plane of the second substrate face each other. A bonding layer is between the first insulating layer and the second insulating layer. A protection film is in contact with the first substrate, the first insulating layer, the bonding layer, the second insulating layer, and the second substrate.

摘要： A novel human interface excellent in operability is provided. Furthermore, a novel data processor excellent in operability is provided. Furthermore, a novel data processor, a novel display device, or the like is provided. An input/output device that receives image data and supplies positional data, and an arithmetic device that supplies the image data and receives the positional data are included. The input/output device includes a first region, a second region, and a bend portion between the first region and the second region. Each of the first region and the second region includes a display portion and a positional data input portion that overlaps the display portion. The arithmetic device includes an arithmetic unit and a storage unit that stores a program to be executed by the arithmetic unit.
