Abstract

A compound having the structure of general formula I is useful as a liquid crystal composition and as a photoelectric display device including the liquid crystal composition. The compound having the structure of general formula I is chemically and physically stable, and has higher clearing point, and both large dielectric anisotropy and large optical anisotropy at the same time. The compound having the structure of general formula I is well compatible with other liquid crystal compounds when applied in a liquid crystal composition, the composition has good stability especially in a low-temperature environment, the characteristic of fast response and a wide range of applicabilities, especially applicable to the IPS-type and TN-TFT-type liquid crystal display devices.
