Abstract
A display device (10) having first and second substrates (12) and (30) and a layer of a PSCT or PFCT liquid crystal material disposed therebetween. The display is driven by an addressing scheme in which voltages are applied either in phase or out of phase in order to switch the liquid crystal material between stable states.
