Abstract
The present invention provides an electrochromic device which is especially suitable as a window, mirror or display element, characterized by a multi-layer construction with at least one layer, enclosed between two coated electrodes, of a material which is either ionically- or mixed ionically- and electronically-conductive, whereby at least one of the two electrode layers consists of transparent material and the ionically- or ionically- and electronically-conductive material is at least so long transparent as no excitation takes place by the application of voltage via the electrodes.
