ABSTRACT OF THE DISCLOSURE The disclosure describes a transparent electrode for an electrolytic display cell comprising a first transparent conducting oxide layer having a configuration suitable for display purposes and deposited on an electrically insulating transparent support. The first transparent conducting oxide layer is coated with a thin transparent second conducting layer of an oxide which differs from that of the first layer and which makes it possible under the operating conditions of the cell to limit the overvoltage on the electrode. The optical transmission and the electrical conduction character- istics of the electrode are slightly reduced with respect to those of the first layer. The second layer is electrochemi- cally etched and the thus exposed portions of the first layer are chemically etched so as to obtain a conductive coating of a given configuration.
