Abstract
A liquid crystal composition having a negative dielectric anisotropy is disclosed. The liquid crystal composition includes compounds of Formulas I to IV. The composition has a low threshold voltage, a low rotary viscosity, a high resistivity, a high voltage holding ratio, and a good high temperature and UV stability. The LC medium has the advantage of obviously reduced response time after polymerization under UV irradiation, thus having important application value.
