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.
