Abstract

An electrochromic display device composed of a pair of oppositely disposed electrode plates at one of which is transparent, and an electrochromic composition sealed between the pair of electrode plates. The electrochromic composition is composed of an electrochromic compound coloring in a reduced state and a solvent. The electrochromic compound coloring in a reduced state is sealed between the electrode plated in a reducing atmosphere. The solubility of the electrochromic compound to the solvent is 10-2mol/(100 g solvent) or more in a reduced state and 10-1mol/(100 g solvent) or more in an oxidized state. The solvent is preferably composed of water and at least 70% by weight of alcohol. The alcohol is desirably polyhydric alcohol.
