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 flexible, highly reliable power storage device or light-emitting device. The device includes a battery unit or a light-emitting unit and a member with rubber elasticity. The battery unit includes a secondary battery. The light-emitting unit includes a light-emitting element. The member with rubber elasticity is provided with a first projection and a second projection. The first projection and the second projection are arranged on a first surface of the battery unit or the light-emitting unit. The first projection and the second projection come in contact with each other when the power storage device is bent such that the first surface of the battery unit faces inward.

Abstract: A light-emitting element includes a stack of a first light-emitting layer emitting fluorescent light and a second light-emitting layer emitting phosphorescent light between a pair of electrodes. The second light-emitting layer includes a first layer in which an exciplex is formed, a second layer in which an exciplex is formed, and a third layer in which an exciplex is formed. The second layer is located over the first layer, and the third layer is located over the second layer. An emission peak wavelength of the second layer is longer than an emission peak wavelength of the first layer and an emission peak wavelength of the third layer.

Abstract: A bendable display device, lighting device, or electronic device which is unlikely to be broken when handled. The display device, lighting device, or electronic device includes two flexible substrates, and at least one of the two flexible substrates contains a plurality of glass fibers extending in one direction. Accordingly, the display device, lighting device, or electronic device has low flexibility in the one direction and is unlikely to be broken when handled.

Abstract: A display device, an electronic device, or a lighting device that is unlikely to be broken is provided. A flexible first substrate and a flexible second substrate overlap with each other with a display element provided therebetween. A flexible third substrate is bonded on the outer surface of the first substrate, and a flexible fourth substrate is bonded on the outer surface of the second substrate. The third substrate is formed using a material softer than the first substrate, and the fourth substrate is formed using a material softer than the second substrate.

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.
