Abstract
The present invention is an electrochromic device which is provided with a first electrode; an electrochromic layer which is disposed on the first electrode, while containing an organic/metal hybrid polymer that contains at least an organic ligand and a metal ion to which the organic ligand is coordinated; an electrolyte layer which is disposed on the electrochromic layer; a counter electrode material layer which is disposed on the electrolyte layer and contains a conductive polymer; and a second electrode which is disposed on the counter electrode material layer. The conductive polymer may be at least one polymer that is selected from the group consisting of polypyrroles, polyanilines, polythiophenes, poly(p-phenylene)s, poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate)s (PEDOT:PSS), polyfluorenes, poly(p-phenylenevinylene)s, polythienylenevinylenes and organic/metal hybrid polymers.
