In this research, the image-sticking property of the in-plane switching (IPS)-liquid crystal display (LCD) with residual d.c. voltage on a rubbed polyimide surface was studied. The voltage holding ratio (VHR) and residual d.c. voltage were measured by the capacitance-voltage hysteresis method in the IPS-LCDs. It was found that the VHR increased with increasing specific resistivity of fluorine-containing LCs. The residual d.c. voltage decreased with increasing concentration of cyano-containing LCs. The residual d.c. voltage is thus decreased by the high polarity of cyano-LCs.
