PROBLEM TO BE SOLVED: To provide a wide nematic phase range, a low viscosity, and an appropriate optical dielectric Δ corresponding to a display mode to be used. n, particularly suitable properties for practical use, such as a suitably high Δn for complex systems such as PDLC, and sufficiently good and suitable compatibility with polymer precursors, especially for complex systems. Providing a liquid crystal medium having SOLUTION: It has an isothiocyanate group at a terminal and has 2 A strong positive dielectric liquid crystal component A having a birefringence Δn greater than 0.3 at 0 ° C. and 589.3 nm, and a positive dielectric component having a wide nematic phase range, preferably a terminal polar bi or terphenyl Or liquid crystal media comprising further ferroelectric liquid crystal components B comprising biphenylcyclohexane compounds, furthermore liquid crystal displays comprising these media, in particular PDLC displays and especially holographic PDLC displays. |
