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: It is an object to improve light extraction efficiency in a light-emitting device and a lighting device. A light-emitting device includes a plurality of light-emitting portions, and a plurality of hemispherical components provided so as to overlap with the plurality of light-emitting portions. The plurality of hemispherical components are provided so as not to form a space therebetween in a region where the plurality of hemispherical components are adjacent to each other. When a refractive index of the hemispherical component is n and a radius of a bottom surface of the hemispherical component is b, the light-emitting portion is provided inside a circle whose radius r from a center of the bottom surface of the hemispherical component is b/n.

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.
