ABSTRACT:
Between each transparent pixel electrode driven by TFT as a drive device and a common electrode, a polymer layer located in contact with the transparent pixel electrode and electrically active to change in color by electrochemical oxidization or reduction and a polymeric solid electrolytic layer located in contact with the polymer layer and containing a coloring agent are interposed. since electrochemical oxidization or reduction brings about a color change, the contrast and the black concentration can be enhanced, and bronzing after long-time use does not occur.
