摘要： A liquid crystal display has a nematic liquid crystal (60), opposite sides of which are contacted by respective orientation films (50, 51). Electrodes (40, 41, 42) on opposite sides of the nematic liquid crystal (60) are used to control the transmission of light through the nematic liquid crystal (60) and polarizing plates (10, 11) by varying the optical rotation of polarized light through the nematic liquid crystal (60). In such an arrangement:

i) the dielectric constant anisotropy of the nematic liquid crystal (60) is at least 4 ;
ii) the orientation films (50, 51) are arranged so that the nematic liquid crystal (60) has a twist angle greater than 90° but not greater than 150° ;
iii) the electrode (42) on one side of the nematic liquid crystal forms a matrix of active elements and a drive circuit (90) applies an alternating voltage to the other electrode (40); and/or
iv) the liquid crystal display includes a phase difference plate (20, 21) with the product of the thickness and refractive index anisotropy of the phase difference plate (20, 21) being at least 0.005µm but not greater than 0.2µm.

In this way, the voltage needed to switch the liquid crystal display between the state in which it passes light and the state on which it blocks light may be reduced.
