LIQUID-CRYSTAL MEDIUM HAVING A LOW THRESHOLD VOLTAGE

摘要

The invention relates to a liquid-crystal medium containing a mixture of at least two compounds of the general formula (I): R<1>-Am-Bn-Z<1>-C-Z<2>-D-R<2>, characterized in that the mixture contains a) 30-90 wt.- % of the compounds of the general formula (I) with DELTA epsilon >/= 9 (= highly polar compounds); b) 0-30 wt.- % of compounds of the general formula (I) with 1 < DELTA epsilon < 9 (= polar compounds); c) 10-40 wt.- % of compounds of the general formula (I) with -1
