Abstract
Disclosed is an electrochromic display device comprising: a first substrate; a first electrode; a second substrate; a second electrode; and an electrochromic composition layer, wherein the device is of a passive matrix drive where the device performs a display by an energization between the electrodes, and performs a erasion of the display, wherein the first electrode comprises electrodes, the second electrode comprises a plurality of transparent display electrodes, a pixel is formed where the electrodes are in a grade separated crossing, at least a surface of the electrodes is respectively oxidized, the electrochromic composition layer comprising (i) insulative partition walls and (ii) an electrochromic composition including a supporting electrolyte, a polar solvent, and a leuco dye, and wherein the device displays a selected pixel by applying a voltage of a first potential difference, and applies the voltage of a second potential difference so as not to cause any energization.
