ABSTRACT:
An electro-optical display device including a substrate which carries a layer of electrodes containing one or more semi-conductive metal oxides. Over particular sections of its surface the layer of electrodes is provided with a metal coating. In these sections (25) the layer of electrodes (20) includes a portion (22) of the metals in elementary condition, which portion becomes greater from the area (A) adjacent to the substrate to the area (0) facing away from the substrate. The metals are available in combined condition in the semi-conductive metal oxides.
