An image display device in which image data produced by an image scanner separate from the display may be written and erased. The display consists of a movable endless belt. Four embodiments are shown with the belt being made of an electrochromic material which electrochemically shows oxidation-reduction reactions; an optically reversible photochromic material; a thermoplastic sheet produced by applying a photoconductor and a thermoplastic resin to a transparent conductive film; and a color photochromic sheet made up of a photochromic film whose absorption changes when illuminated by light of predetermined wavelengths and a repetitive sequence of color filters of red, green and blue each being formed in a stripe configuration, respectively. Visible images are displayed on the display member based on the image data.
