ABSTRACT:
A display element which has an electrolyte layer containing silver or a compound containing silver in the chemical structure thereof and an electrolytic solvent between opposed electrodes, and also contains a porous white scattering material between said opposed electrodes, wherein said opposed electrodes can be operated so as to dissolve silver or deposit silver, characterized in that said porous white scattering material is incorporated through a step of imparting an aqueous intimate mixture containing a water-soluble polymer substantially insoluble in said electrolytic solvent and a white pigment onto a component between said opposed electrodes, followed by drying. The above display element is composed of simple and easily available members, can be operated with a low voltage, exhibits high display contrast and satisfactorily high reflectance for the white display, and is reduced in the fluctuation of the white reflectance.
