We propose a novel mechanism of short-term image-sticking phenomenon in in-plane switching liquid crystal displays (IPS LCDs) that is related to ionic relaxation generated by a vertical electric field caused by a flexoelectric effect. We discuss the differences between electric fields caused by the flexoelectric effect and those caused by DC bias voltage.
