We propose a liquid crystal actuator using the backflow effect in the nematic π-cell in which a unidirectional flow is generated after the electric field is removed. Applying rectangular AC voltage continuously drives dispersed objects in the π-cell in the direction of rubbing. Using this actuator, we drive microspheres and a film. The drive velocity of dispersed objects depends on the amplitude and frequency of applied voltage.
