One object of the present invention is to provide an electrochromic device (70) having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer (75), upper conductive layer (71), an electrochromic electrode layer (74a,b), a counter electrode layer (72), and at least one ion conductor layer (73a,b, 77) sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower conductive layer and the electrochromic electrode layer are scribed and the gap (P1) formed from the scribing is filled with the layers formed above the electrochromic electrode layer. In some aspects, the ion conductor layer is also scribed with the lower conductor and electrochromic electrode layers and the gap formed from the scribing is filled with the layers formed above the ion conductor layer. In further aspects, the insulating film may include one or more buffer layers (76) formed above an ion conductor layer, further separating the upper conductive layer from the lower conductive layer.
