Electrochromic device by oblique evaporation to improve the response of coloration and bleaching
 An electrochromic device includes a layer of electrochromic material, such as tungsten oxide, which is deposited by oblique evaporation at an acute angle of incidence in the range of from 10.degree. to 90.degree. between the normal to the substrate and the direction of the evaporation. Due to the anisotropic topography achieved by the oblique evaporation, the layer of electrochromic material exhibits improved fast response and long life time of cycling of coloration and bleaching.
