A method for preparing and operating dynamic scattering liquid crystal display cells having internal electrodes and containing a smectic liquid having positive dielectric anisotropy and incorporating a homeotrophic alignment inducing medium for the smectic liquid filling. The cell can be switched off to make the transition from dynamic scattering to static scattering for providing indefinite storage properties.
