ABSTRACT:
A novel liquid crystal display device which enables continuous gray-scale display, has a wide viewing angle and readily allows an active-matrix drive. The liquid crystal display device has a pair of substrates and a liquid crystal material having an antiferroelectric phase sandwiched between said pair of substrates, at least one of the substrates undergoing an aligning process. In the liquid crystal display element, a natural helical pitch of the liquid crystal material is smaller than a gap between the substrates, and moreover, smaller than twice a lower-limit wavelength of the wavelength range of light used in the liquid crystal display device.
