Abstract
An electrochromic device is provided. The device includes a first substrate and a second substrate. The device includes electrochromic material, with the first substrate, the electrochromic material and the second substrate forming a laminate, the first substrate offset in a lateral direction from the second substrate along at least a portion of an edge of the electrochromic device. The device includes a plurality of terminals coupled to the electrochromic material, with at least two of the plurality of terminals exposed on the first substrate by the first substrate being offset in the lateral direction from the second substrate. A method of manufacturing an electrochromic device is also provided.
