Abstract
The invention relates to liquid-crystalline compounds of the formula (I) having a —CF2O— bridge. The invention also relates to liquid-crystalline media prepared therewith and to liquid-crystal display devices (LC displays) containing these media. This kind of compounds has the excellent characteristics including a large dielectric anisotropy, fast response time and high clearing point, and good miscibility at low temperature in the same time which has important significance in new TFT LC mixture.
