Ferroelectric liquid crystals have developed from the early single component chiral systems, that brought a wealth of fundamental knowledge, to multi-component achiral host systems with optimised physical properties that have a small quantity of chiral dopant added to provide the required ferroelectricity. The research into ferroelectric liquid crystals has been intense, but the technology has not yet proved commercially viable. This paper discusses the developments in ferroelectric materials and focuses on the ferroelectric mixtures generated from ortho-difluoroterphenyl host materials and the chiral cyanohydrin dopants which have: a high dielectric biaxiality and are suitable for use in tauV(min) devices. Such ferroelectric mixtures have been incorporated into structurally matched diacrylates and polymerised to form a gel network, and the interesting results of these systems are discussed in comparison with the conventional ferroelectric mixtures.
