Abstract
An electrochromic apparatus includes a first substrate, a first electrode layer, an electrochromic layer, an electrolyte layer, a second substrate, a second electrode layer, a first extraction electrode layer, a second extraction electrode layer, and a partition wall. The first extraction electrode layer contacts the first electrode layer and is isolated from the second electrode layer and the electrochromic layer. The second extraction electrode layer contacts the second electrode layer and is isolated from the first electrode layer and the electrolyte layer. The partition wall is electrically insulative and sandwiched between the first extraction electrode layer and the electrolyte layer and between the second extraction electrode layer and the electrolyte layer.
