Abstract

Electrode and specifically a transparent electrode for an electrolytic cell and specifically an electrolytic display cell constituted by a transparent conducting layer having a configuration suitable for display purposes and deposited on an electrically insulating transparent support. The transparent conducting layer is coated with a thin transparent conducting film made from a material different from that of the conducting layer, so that under the operating conditions of the cell it is possible to limit the overvoltage on the electrode to such a value that there can be no secondary reactions liable to bring about a transformation of the materials forming said layer and said film. The layer is made from tin-doped indium oxide and the film from tin oxide doped with antimony or cadmium.
