Abstract
Ferroelectric liquid crystal compositions including organic ion pair compounds wherein image sticking is reduced or eliminated. Use of the ferroelectric liquid crystal compositions in a ferroelectric liquid crystal display device allows for rapid image refresh rates without required a DC-balancing algorithm. The organic ion pair compounds provide electrical resistivity values for the compositions that result in reduced image sticking when the compositions are used in FLC display devices.
