Abstract
Abstract Between a display electrode and a counter electrode, an all-solid-state organic electrochromic display device comprises a polymer layer comprising at least one organic electrochromic material and at lest one ionic material. The layer may be a polymer film of at least one polymer material in which film the electrochromic and the ionic materials are dispersed, a polymer electrochromic film comprising the electrochromic material in which film the ionic material is dispersed, a polymer ionic film comprising the ionic material in which film the electrochromic material is dispersed, or a polymer electrochromic and ionic film comprising the electrochromic and the ionic materials. Between the electrochromic layer and the counter electrode, the device may comprise a polymer redox layer which is similar in structure to the electrochromic layer and preferably comprises at least one ionic material. Between the electrochromic layer and either one of the display and the counter electrodes or the redox layer, the device may comprise a solid electrolyte layer which may either be a polymer ionic layer or an inorganic solid electrolyte layer. Preferably, the electrochromic, the redox, and/or the polymer ionic layer include conductive powder, at least one plasticizer, and/or reflective powder and, more preferably, are cross-linked. A conductive and/or reflective powder may be included in the inorganic solid electrolyte layer.
