Abstract
An electro-chromic display device comprises an electro-chromic material and an electrolyte between a display electrode formed by a combination of a plurality of segments, and counter electrode disposed opposite thereto, and undergoes a reversible reaction for developing or erasing a color upon application of voltage or reverse polarity voltage. The counter electrode comprises a molded product obtained by molding under pressure a mixture of the powders of a solid oxidation-reduction type active material and an electrically conductive material.
