Abstract: A description is given of a film for a film capacitor which is formed from an electrically insulating carrier film with an electrically conductive layer applied thereon, the electrically conductive layer in the film capacitor forming an electrode and the carrier film forming a dielectric. The invention is distinguished by the fact that the electrically conductive layer 2 is made as thin as possible, and that, in order to reduce the total sheet resistance on the electrically conductive layer 2, at least one current path 4, 5 is provided which has a lower sheet resistance than the electrically conductive layer.

Abstract: A controllable electrochromic indicator device is disclosed which includes two electrodes, an electrochromic layer and an adjacent charge-carrier-transmitting insulator layer situated between the two electrodes and at least one of the electrodes being deposited on a supporting plate and at least one of the electrodes being transparent. The charge carrier transmitting insulator layer is a good ion conductor and functions to almost completely block the flow of electrons. At least one of the electrodes is non-polarizable and is disposed in direct contact with the ion conductor.
