Abstract
A photowriting display device which is capable of performing bright full color display and a photowriting display apparatus which incorporates the photowriting display device and on which the pen moving operation is directly reflected as information to be displayed. A photowriting display device is disclosed which incorporates: an electrochromic display member incorporating a photoconductor in which only regions irradiated with writing light generate carriers to realize conductivity; an electrochromic layer in which light absorption of the regions are reversibly changed owing to electrochemical oxidation and reduction reactions caused to occur due to the conductivity; an electrolyte in which the electrochromic layers are laminated or an electrochromic material is dissolved; and a pair of electrodes laminated through the photoconductor, the electrochromic layer and the electrolyte. A plurality of the electrochromic display members are laminated.
