Abstract
A display device suitable for timepieces and the like includes a solid electrochromic material and a solid electrolyte. The device is free of liquid components and is substantially thinner than conventional display devices. The problem of leakage arising from the use of liquid electrochromic material or liquid electrolyte is avoided.
