Description

technical field

[0001] The present invention relates to compounds as components of liquid-crystalline media, their preparation and use. Background technique

[0002] Liquid crystal materials are substances with a liquid crystal phase between a solid phase and a liquid phase, and are mainly used as dielectrics in displays because the optical properties of such substances can be changed by an applied voltage. Electro-optic devices based on liquid crystals are well known to those skilled in the art, in which various effects may be incorporated. Examples of such devices are liquid crystal cells with dynamic scattering, DAP (distorted alignment phase) liquid crystal cells, guest / host type liquid crystal cells, TN cells with twisted nematic structure, STN (super twisted nematic) liquid crystal cells, SBE ( super birefringence effect) liquid crystal cell and OMI (optical film interference) liquid crystal cell. The most common displays are based on the Schadt-Helfrich effect and h...
