ABSTRACT:
Electrolytic display cell of the type comprising a transparent electrode of shape suitable for display purposes, a counter-electrode made from metal, called primary metal, an electrolyte inserted between the electrode and the counter-electrode, and means for supplying the electrode and counter-electrode with electric power so as to bring about in certain parts of the electrode the deposition or dissolving of a metal coating formed from the primary metal, wherein the counter-electrode is continuous and also comprises an electricity conducting material, which is chemically and electrochemically inert under the operating conditions of the cell, the said material and the said metal being associated in the counter-electrode in such a way that the primary metal is in contact with the electrolyte and the electricity conducting material forms a continuous film.
