Abstract
An electrochromic display device includes an electrolyte and at least one transparent electrically conductive electrode. An organic insulating layer e.g. a photoresist material, is disposed between the transparent electrode and the electrolyte such that no portion of the transparent electrode is in contact with the electrolyte. The insulating layer protects the transparent electrode from deterioration so as to increase the lifetime of the transparent electrode.
