Abstract
A novel edge design for a laminated electrochromic device containing an ion-conducting material layer prone to moisture gain or loss disposed between first and second substrates is disclosed. The device is characterized by a continuous nub on its circumferential edge which is aligned with the ion-conducting material interface between the substrates forming the device. The nub can be used to interlock with a peripheral edge seal.
