    Abstract: To provide a display device that is suitable for increasing in size. To provide a display device in which display unevenness is suppressed. In a display device, a plurality of display panels are arranged to partly overlap one another. In two of the overlapping display panels, a display panel positioned on the display surface side includes a region transmitting visible light that is adjacent to a display portion, and the region transmitting visible light overlaps with a pixel of a display panel positioned on the lower side. Furthermore, in at least a display portion of the display panel placed on the lower side, an aperture ratio of the pixel overlapping with the region transmitting visible light of the display panel on the upper side is higher than an aperture ratio of another pixel.

    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.
