Electrochromic device and electronic device

Abstract

An electrochromic device, comprising a first conductive base layer, an electrochromic layer and a second conductive base layer stacked in sequence. The first conductive base layer comprises a first transparent conductive layer and a first base material layer stacked in sequence; the first transparent conductive layer is adhered to one side of the electrochromic layer; the second conductive base layer comprises a second transparent conductive layer and a second base material layer stacked in sequence; the second transparent conductive layer is adhered to the other side of the electrochromic layer; a partition groove is provided in the second transparent conductive layer for partitioning the second transparent conductive layer into a first conductive area and a second conductive area independent of each other; a conduction member is provided on the second conductive area, and the first transparent conductive layer is electrically connected to the second conductive area by the conduction member.
