Abstract
The solid electrochromic element of this invention is to be used for various types of dimmers and displays, and comprises a pair of electrode layers, an oxidation color-developing layer, an ion-donating layer and a reduction color-developing layer laminated one upon another on a substrate. In the manufacture of this type of electrochromic element, the pair of electrode layers and the ion-donating layer are formed by the ion plating technique. The dimmers of this invention for automotive sun roof, side-watching window and glare-free mirror each contains an electrochromic element manufactured by the process mentioned above. The light transmittance of the sun roof and side-watching window, as well as the intensity of reflecting light at the glare-free mirror, are appropriately controlled according to the conditions of their use by application of a variable voltage across the two electrode layers of the electrochromic element.
