Liquid-crystalline medium having a dielectric anisotropy Deltaepsilon of >=3, comprising compounds of the general formula (I), in which R is as defined herein, are suitable for use as liquid-crystalline media for, e.g., IPS, MLC, TN or STN displays, but in particular for LCoS displays. The media have very high specific resistance values, low threshold voltages, short response times and high birefringence values Deltaepsilon, while maintaining other boundary conditions.
