Abstract: An electronic device usable in a manner similar to reading a book and a novel electronic device are provided. The electronic device includes flexible first to n-th display panels (n is a natural number of 4 or more) and an shaft. The first to n-th display panels each include a first surface and a second surface opposite to the first surface. The first and second surfaces are provided with the first and second display portions, respectively. The shaft includes an operating circuit, to which the first to n-th display panels are electrically connected. The first display panel and the second display panel nearest to the first display panel are fixed to the shaft so that an angle formed by straight lines connecting a portion where the first display panel projects from the shaft and the center of the shaft and connecting a portion where the second display panel projects from the shaft and the center of the shaft is (360/n)° in a cross-sectional view along a plane orthogonal to an extending direction of the shaft.

Abstract: A highly reliable display device. A first flexible substrate and a second flexible substrate overlap each other with a display element positioned therebetween. Side surfaces of at least one of the first substrate and the second substrate which overlap each other are covered with a high molecular material having a light-transmitting property. The high molecular material is more flexible than the first substrate and the second substrate.

Abstract: A display device suitable for increasing in size, a display device where display unevenness is suppressed, or a display device that can display an image on a curved surface is provided. The display device includes a first display panel, a second display panel, a first adhesive layer, and a substrate. The first and second display panels each include a first region, a second region, and a barrier layer. The barrier layer includes a portion overlapping with the first region and a portion overlapping with the second region. The first region includes a region transmitting visible light. The second region can display an image. The barrier layer contains an inorganic insulating material and includes a region in contact with the first adhesive layer and a region with a thickness of 10 nm to 2 μm. The display device includes a region where the substrate, the first adhesive layer, the first region of the second display panel, and the second region of the first display panel overlap each other.

Abstract: A highly reliable display device. A first flexible substrate and a second flexible substrate overlap each other with an element positioned therebetween. A periphery of the overlapped first and second substrates is covered with a high molecular material having a light-transmitting property. The high molecular material is more flexible than the first substrate and the second substrate. As the element, for example, an EL element can be used.

Abstract: A display device which can display a two-dimensional image that gives a viewer a strong sense of depth or three dimensions is provided. A display device includes a light-transmitting layer with a viewing surface and a convex surface facing each other, and a display region in which a plurality of display elements for displaying an image toward the viewing surface are provided along the convex surface. In the display device, the refractive index of the light-transmitting layer is higher than the refractive index of the atmosphere, and the viewing surface is a surface intersecting the convex surface at three points, or a distance between a foot N of a perpendicular line drawn from a point M on the convex surface to the surface and an intersection P of the perpendicular line with the viewing surface is largest when the point M is at an outermost point.
