Based upon Erickson-Leslie hydrodynamic equations, we study 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 the velocity of flow are obtained. An abnormal director profile caused by the backflow appears after the switch of a holding voltage.
