Abstract:
Provided is a novel electrochemical display element which performs bright white display, high contrast black/white display and full-color display with a simple member configuration. A method for driving such display element is also provided. The display element contains an electrochromic compound, which is colored or has its color disappear due to oxidation or reduction, a metallic salt compound, an electrolyte and a white scattered material, between opposing electrodes. The display element substantially performs multiple color display of three colors or more, i.e., black display, white display and colored display other than black, by driving operation of the opposing electrodes.
