Abstract

The invention relates to a liquid-crystalline medium comprising one or more compounds of the formula I in which R0, X0 and L1-6 have the meanings indicated in Claim 1, and to the use thereof in electro-optical liquid-crystal displays.

Description

[0001] This application is a divisional application of the Chinese patent application 200980105554.5 with the invention title "Liquid Crystal Medium". technical field [0002] The invention relates to liquid-crystalline media (FK media), their use for electro-optical purposes, and liquid-crystal displays comprising such media. Background technique [0003] Liquid crystals are mainly used as dielectrics in display devices because the optical properties of such substances can be changed by an applied voltage. Electro-optical devices based on liquid crystals are very well known to those skilled in the art and can be based on various effects. Examples of such devices are cells with dynamic scattering, DAP (distorted aligned phase) cells, guest / host cells, TN cells with twisted nematic (“twisted nematic”) structures, STN (“super twisted nematic”) cells , SBE ("Super Birefringence Effect") cell and OMI ("Optical Mode Interference") cell. The most common display devices are based...
