ABSTRACT:
A dielectrically positive liquid crystalline media comprising:a first dielectrically positive component, component A, comprising a dielectrically neutral compound of formula Iwherein the parameters have the meanings defined herein;a second dielectrically positive component, component B, comprising one or more dielectrically positive compounds having a dielectric anisotropy of more than 3; andoptionally 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,are suitable for use in liquid crystal displays, especially active matrix displays, and in particular TN and to IPS displays.
