ABSTRACT:
A laminate electrochromic display is disclosed in which a layer containing electrode leads addresses a laminate layer of side-by-side working and counter electrodes. A laminate layer of an electrochromic material is disposed on the electrode layer and, optionally, an ionically conductive electrolyte material is included in the electrochromic layer or provided in a separate electrolyte layer disposed over the electrochromic layer. In addition, a sandwich-type electrochromic device is disclosed in which the electrodes serve as either working or counter electrodes and a transparent electrode, disposed over the electrochromic layer serves as the other electrode. The electrochromic layer can optionally contain an ionically conductive electrolyte or, alternatively, a separate layer containing the electrolyte can be disposed between the electrochromic layer and counter electrode layer.
