Abstract: A display device that can display an image along a curved surface is provided. In the display device, a first display panel and a second display panel overlap each other with a light-transmitting layer provided therebetween. The light-transmitting layer is positioned on a display surface side of the first display panel, and on a side opposite to the display surface of the second display panel. The light-transmitting layer has an average transmittance of 80% or more with respect to light in the wavelength range of 450 nm to 700 nm and a refractive index higher than that of air. A display region of the first display panel overlaps a region transmitting visible light of the second display panel with the light-transmitting layer provided therebetween. It is preferred that the display region of the first display panel not overlap with a region blocking visible light of the second display panel.

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: 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: A display device or a display system with which a viewer can feel a strong or natural stereoscopic effect in a two-dimensional image and is less likely to be fatigued is provided. The display system includes a display portion, a detection portion, and a control portion. The display portion is flexible. The detection portion is configured to detect the conditions of a viewer's eye to obtain detection information and to supply the detection information to the control portion. The control portion is configured to extract information on the viewer's fatigue from the detection information and to change the curvature of the display portion on the basis of the information on the viewer's fatigue. The central angle of the curved surface of the display portion is preferably greater than or equal to 20° and less than 90°.

Abstract: To provide a display device that gives a viewer a strong stereoscopic effect or sense of depth or a natural stereoscopic effect or sense of depth in a two-dimensional image, a display device including a display portion having a curved surface is provided. The display portion may be bent in a horizontal direction or a vertical direction. Alternatively, the display portion may have a convex surface or a concave surface on a display surface side. The display device may include a frame portion. A display device including a frame portion and a display portion which has a display surface on a frame portion side, is located so as to be apart from the frame portion with a distance therebetween, and has a curved surface, in which the display portion overlaps with an opening of the frame portion, and an end portion of the display portion overlaps with the frame portion, is provided.
