Two types of fast switching mixtures with high positive dielectric anisotropy were described. The first type, with a birefringence below 0.3, was designed for devices operating at room or lower temperatures and the second one, with a birefringence higher than 0.3 for devices operating at elevated temperatures.

Keywords: isothiocyanatobiphenyls; isothiocyanatoterphenyls; isothiocyanatotolanes; phase transitions; nematic high birefringence mixtures
