Abstract: A battery includes a first insulator, a first electrode layer, and a first counter-electrode layer. The first counter-electrode layer is a counter electrode for the first electrode layer. The first insulator includes a first electrolyte portion, a second electrolyte portion, and a first bent portion. The first bent portion is positioned between the first electrolyte portion and the second electrolyte portion. The first electrode layer is disposed in contact with the first electrolyte portion. The first counter-electrode layer is disposed in contact with the second electrolyte portion. The first insulator is bent at the first bent portion, and thereby the first electrode layer and the first counter-electrode layer are positioned facing each other.

Abstract: There is provided a display device having an electrochromic element placed in the display device. The electrochromic element has: a light transmittance of 70% or more and a light reflectance of 20% or less at a central wavelength of a visible spectrum when in a transparent state; and a light reflectance of 65% or more at the central wavelength of the visible spectrum when in a mirror state. By this, the display device is not only highly effective in terms of light-shielding, heat blocking, screening, etc., but is also switchable between a transmissive type and a reflective type.
Abstract translation: 提供了一种显示装置，其具有放置在显示装置中的电致变色元件。 电致变色元件具有在透明状态下在可见光谱的中心波长处的70％以上的透光率和20％以下的光反射率; 并且当处于镜像状态时，在可见光谱的中心波长处的光反射率为65％以上。 由此，显示装置在遮光，隔热，遮蔽等方面不仅高效，而且可以在透射型和反射型之间切换。
