    摘要: A ferroelectric liquid crystal display includes a cell comprising a layer of ferroelectric liquid crystal material contained between two transparent glass substrates having alignment layers for determining the surface alignment of the molecules in the liquid crystal material. The display further incorporates switching circuitry for switching the molecules in the liquid crystal material between a first state and a second state by means of a switching signal having a duration &tgr; and a voltage V. The liquid crystal material and the alignment layers are such that the cell exhibits a &tgr;-V response in the form of a curve having two minima separated by an intermediate maximum. Such a &tgr;-V response, which may be termed a double turnaround response, allows a high degree of discrimination between the switched and non-switched states beyond the turnaround point and offers potential addressing advantages.
