Abstract
A manufacturing method of electrochromic devices () includes the steps of providing a first and second sheet including a first () and second () plastic substrate, respectively, at least partially coated with a first () and second () electron conducting layer, respectively. The first sheet is at least partially coated with a first electrochromic layer (). The second sheet is at least partially coated with a counter electrode layer (). The first and second sheets are laminated with an electrolyte layer () interposed in-between into an electrochromic laminate sheet (). The electrochromic device is at least partially defined by forming a seal () through the electrochromic laminate sheet () at a distance (D) from a peripheral edge (). The distance (D) is preferably larger than the mean diffusion lengths of oxygen, water or an electrolyte component in the electrolyte during a predetermined time period.
