Title: ELECTROCHROMIC DEVICE, ELECTRODE STRUCTURE THEREFOR, AND MANUFACTURING METHOD THEREOF
Abstract:
Disclosed is an electrochromic device manufactured by a method for forming a bus electrode on an electrochromic layer. A bus electrode is directly formed on the electrochromic layer by using a printing process. In the case of a small area device, a main bus electrode is formed at an edge portion of a first electrode part and a second electrode part. Furthermore, in the case of a large area device, bus electrode arrays are disposed at a center portion of the electrochromic layer as well as at the edge portions, and an insulating film is formed on the surfaces thereof so as to prevent an electrolyte layer and bus electrodes from directly contacting each other. By forming a bus bar and an insulator layer on the electrochromic layer, an electrochromic device is provided, which has a uniform color change rate not only in a small area electrochromic device, but also in a large area electrochromic device, and which has a response rate, in the large area electrochromic device, on which almost no influence is exerted compared to that in the small area electrochromic device.
