Patent ID: 11194215

Abstract:
An electrochromic device includes an electrochromic element 110 including an anode electrode 2a, a cathode electrode 2b, and an electrochromic layer 4, and drive means 120 connected to the electrochromic element. The electrochromic element 110 includes a plurality of anode terminals (A1, A2) electrically connected to the anode electrode 2a, and a plurality of cathode terminals (C1, C2) electrically connected to the cathode electrode 2b, and each of the anode terminals constitutes a terminal pair in combination with one of the cathode terminals. At least part of a first application period in which the drive means 120 applies a voltage to a first terminal pair that is one of the terminal pairs and at least part of a second application period in which the drive means 120 applies a voltage to a second terminal pair that is another one of the terminal pairs are not overlapped with each other.
