ABSTRACT:
The present invention provides an electrochromic display device which can realize a reduction in color drift in storing images and has excellent memory properties. The electrochromic display device is an active matrix drive-type electrochromic display device containing opposed electrodes, at least one type of a porous layer containing titanium oxide with an electrochromic dye adsorbed thereon, and at least one type of a porous layer containing tin oxide. The active matrix drive-type electrochromic display device is characterized in that the tin oxide-containing porous layer is connected to a pixel circuit used in active matrix drive through one of the opposed electrodes.
