摘要： The commercial production of DHF (Deformed Helix Ferroelectric) cells, in particular DHF color display cells, has scarcely become established to date. This is in particular because the DHF cells required for this purpose and based on the known prior art have short switching times and a good angular range of view but relatively high voltages and currents are required for their operation. Moreover, for the production of a DHF cell, the liquid crystal mixture must additionally be oriented or formatted by means of an electric field. The present invention relates to a ferroelectric display cell which does not have these disadvantages and in particular is distinguished by the fact thatthe display is dark at U=0 and bright at .vertline.U.vertline.>0,the current-voltage hysteresis characteristic has two maxima of equal size,the birefringence .DELTA.n in the field-free state is greater than that in the saturated state andthe saturation voltage is relatively low even with very small spontaneous polarization P.sub.s (P.sub.s

摘要： A ferroelectric liquid crystal display comprises two liquid crystal cells disposed one behind the other between two polarizers, one cell having line electrodes and the other having pixel electrodes. The pixel electrodes are driven with image information in synchronism with the line electrodes. The orientation and refractive index of the liquid crystal cells are so chosen that transmission is not substantially altered when the control voltages are reversed. The two displays are so actuated that the switching angle never exceeds .+-.22.5.degree.. The polarity of the voltages is periodically so inverted that on average there is no DC voltage across the cells.
