A standing helix ferroelectric liquid crystal display cell includes: two transparent substrates (A,B); a ferroelectric liquid crystal layer () comprising ferroelectric liquid crystals in a standing helix configuration, the ferroelectric liquid crystal layer () being disposed between the two transparent substrates (A,B), the ferroelectric liquid crystals having a helix axis perpendicular to the two substrates (A,B) and chiral smectic liquid crystal helix pitch shorter than a wavelength of a polarized light normally impinging at least one of the two transparent substrates (A,B); and inter-digital electrodes (), disposed in plane with the two transparent substrates (A,B), configured to apply an electric field to the ferroelectric liquid crystal layer () that provides a driving voltage below a critical voltage for helix unwinding.
