• We propose image sticking resistant liquid crystal display (LCD) driven by fringe electric field for mobile application. For use of an alignment layer with polyamic acid (PA) type without cross link agent, impurity ions absorbed on the alignment layer easily discharge irrespective of liquid crystal (LC) because there is not any cross link agent which prevents discharging the ions, resulting in that image sticking easily disappears. For a panel with use of an alignment layer with polyimide (PI) type, time dependant flicker value is less than 2 dB and very steady while it is more than 10 dB and dramatically changes for a panel with the PA coated. From the result, we can know the PA coated panel without cross link agent has advantage in fast discharge of impurity ions when voltage is off, which is very favorable to an approach to image sticking free LCD driven by fringe electric field for mobile devices.
