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.
