— By adding a uniaxial retardation film and using a chlorinated LC mixture, the performance of polymer‐dispersed LCDs with crossed Nicols (PDN‐LCDs) was improved. A wide viewing angle of more than 60° (contrast ratio >5) for all azimuth directions was obtained. In the horizontal and vertical viewing azimuth, the contrast ratio was over 30 even at an inclination viewing angle of 60°.
