Abstract
The present application provides an electrochromic device, which comprises a first substrate layer, a first conductive layer, a solid-state color changing layer, a second conductive layer and a second substrate layer which are stacked in sequence. A varnish layer is disposed at an edge region of the first conductive layer and/or an edge region of the second conductive layer. The Dyne value of the varnish layer minus the surface tension of a slurry of a structure layer in the solid-state color changing layer which is in contact with the first conductive layer or the second conductive layer is less than or equal to 5 mN/m. Since the varnish layer is arranged, when the solid-state color changing layer is coated, the slurry of the solid-state color changing layer cannot be attached to the varnish surface. Therefore, wiping is not required, and a number of problems caused by wiping are avoided. Otherwise, the adhesion of the solid-state color changing layer to the varnish surface is reduced. Moreover, the arrangement of the varnish defines the boundary of wiping and ensures the progress of wiping.
