Abstract
Abstract An electrochromic layer system, in particular for motorcar mirrors, comprising one first transparent, electrically conductive layer deposited on a glass carrier and serving as an electrode, one electrochromic layer, one second electrically conductive layer serving as a backplate electrode, and one reflecting layer. The electrochromic layer includes at least one oxidation-reduction layer as a metal oxide layer or a polymer layer having a conjugate double bond system, which is deposited upon the electrode. Hence, preferably a storage layer for ions is also provided.
