Abstract

The invention describes an electrochromic display element in the form of an electrically dimmable mirror, an optical filter having an electrically alterable transparency or a display element which contains an electrochromic liquid between two electrode sheets, where at least one of the electrode sheets is transparent and has a transparent, electrically conductive layer and the transparent electrode sheet has a pattern of strips or grid made of a material having metallic conductivity in order to produce a uniform coloration of the electrochromic liquid.
