A supported or self-supporting electrochromic device is provided having (a) at least one electrochromic element comprising (i) at least one material that is electrically conducting in at least one material that is electrically conducting in at least one oxidation state and (ii) at least one electrochromic material, wherein said materials (i) and (ii) can be the same or different, (b) at least one layer of a solidified electrolyte which is in direct electrical contact with said electrochromic element, and (c) at least two electrodes adapted to be electrically connected to a voltage supply so as to create a difference in potential therebetween, with each of said electrodes being in direct electrical contact with at least one of said electrolyte layer(s) and not in direct electrical contact with said electrochromic element. Displays incorporating such a device, as well as processes for the production of such a device are contemplated. A method for addressing an electrochemically active element also is provided.
