ABSTRACT:
In a method of driving a liquid crystal element constituted by interposing a bistable ferroelectric liquid crystal between electrodes, a driving method of a liquid crystal element having a memory property characterized in that a first voltage signal the absolute value of a peak value of which is less than a predetermined value is applied to the ferroelectric liquid crystal in order to keep a light transmission state of said liquid crystal element, and a second voltage signal the absolute value of a peak value of which is over the predetermined value is applied to the ferroelectric liquid crystal in order to change the light transmission state of the liquid crystal element.
