Here is presented a nematic LCD based on a novel orientational effect in suspension of the nematic liquid crystal (NLC) with solid nanoparticles, controlled by the optically “hidden” electrophoretic effect: electrophoretically controlled nematic (EPCN) [1,2]. Polarity controlled electromigration of the nanoparticles, results in the stabilization of the molecular alignment and provides the bistable/multistable switching in a conventionally designed LC structure. Multistability, provided by the electrophoretically controlled birefringence effect, allows multistable color switching, stabilized at zero field. This makes it easier to introduce into conventional nematic LC technology a polarity‐controlled bistable/multistable switching with color capability and gives to standard LCD fabrication technique a big opportunity for developing low consumption high informative displays, including low cost large scale flexible displays.
