Abstract: An electrochromic device is provided. The electrochromic device may include a plurality of auxiliary electrodes spaced apart from each other in both a first direction and a second direction. The electrochromic device may improve an electrochromism rate and prevent a drive failure problem due to oxidation of the auxiliary electrode from spreading.
