Abstract

Based upon the Ericksen-Leslie hydrodynamic equations, we studied an inverse twisted nematic liquid crystal cell, in which the liquid crystal is untwisted in the field-off state and twisted in the field-on state. The time evolution of director configuration and velocity of flow was obtained by computer simulation. An abnormal director profile that caused by the backflow appeared after switching on the holding voltage. We also compared the optical transmittance of the inverse twisted nematic liquid crystal cell having backflow effect with that without considering backflow effect.
