ABSTRACT:
An electrochromic element including a pair of electrochromic bases is provided. Each electrochromic base is defined by a substrate, an electrode layer disposed on the substrate, and a color-forming layer disposed on the electrode layer. The electrochromic bases are superposed such that their respective color-forming layers face each other. A solid electrolyte of ultraviolet-setting type is disposed between the color-forming layers of the electrochromic bases. The method of manufacturing the electrochromic element and the method of driving the same are also disclosed.
