This invention relates to a polymeric electrolyte for an electro-optical device including an electrode provided with an electrochromic layer and a counter electrode which comprises a mixture of a protonic polymer and water in which the product of the water content and the gram equivalent weight of polymer is equal to or less than the product of the molecular weight of water and the number n of water molecules bonded per anion group of each monomer of the polymer, the number n being 6 in the case of a sulphonic polymer.

The electrolyte, which may be used, e.g. in a display cell including an electrode provided with an electrochromic layer, for example WO.sub.3, and a counter electrode, is inert relative to the electrochromic layer.
