Liquid crystalline medium and liquid crystal display

摘要

The instant invention relates to dielectrically positive liquid crystalline media comprising
- a first dielectrically positive component, component A, comprising a dielectrically neutral compound of formula I
wherein the parameters have the meaning given in claim 1 and
- a second dielectrically positive component, component B, comprising one or more dielectrically positive compounds having a dielectric anisotropy of more than 3 and
- optionally a dielectrically neutral component, component C, comprising one or more dielectrically neutral compounds having a dielectric anisotropy in the range from -1.5 to 3,
their use in liquid crystal displays as well as to liquid crystal displays comprising these media, especially to active matrix displays and in particular to TN and to IPS displays.
