Abstract
According to one aspect of the present disclosure, an electrochromic element comprises: a first electrode; a second electrode; a peripheral seal disposed between the first electrode and the second electrode; and an electrochromic layer disposed in a space defined by the first electrode, the second electrode, and the peripheral seal, wherein the electrochromic layer includes an anodic electrochromic compound and a cathodic electrochromic compound, wherein the peripheral seal is an anode preferential peripheral seal that takes preference of oxidation reaction of anodic electrochromic compound near the peripheral seal, and wherein the anodic electrochromic compound in the electrochromic layer has a concentration greater than a concentration of the cathodic electrochromic compound.
