摘要： A nematic liquid crystal composition of the present invention is used in liquid crystal display devices of the TN mode, OCB mode, ECB mode, IPS mode, or VA-IPS mode. The liquid crystal composition has positive dielectric anisotropy. Since the refractive index anisotropy and the nematic phase-isotropic liquid phase transition temperature are decreased and the increase in the lower limit temperature of the nematic phase is suppressed, the viscosity of the liquid crystal composition is sufficiently low without degrading the nematic phase temperature range. The liquid crystal composition also offers excellent features such as high-speed response, good display quality, and less display failures and is thus suitable as a practical liquid crystal composition.
摘要翻译： 本发明的向列型液晶组合物用于TN模式，OCB模式，ECB模式，IPS模式或VA-IPS模式的液晶显示装置中。 液晶组合物具有正的介电各向异性。 由于折射率各向异性和向列相各向同性液相转变温度降低，并且向列相的下限温度的上升被抑制，所以液晶组合物的粘度足够低，而不降低向列相温度范围。 液晶组合物还具有高速响应，显示质量好，显示不良等优异的特性，因此适用于实用的液晶组合物。

摘要： A tetrahydronaphthalene derivative represented by the general formula (I) and a liquid crystal composition containing the same. A compound represented by the general formula (I) shows superior liquid crystallinity and co-solubility with conventional liquid crystal compounds and compositions. Furthermore, addition of such a compound enables the threshold voltage to be significantly reduced with almost no deleterious effect on the responsiveness. In addition, a compound of the present invention can also be easily produced industrially, is colorless, and is chemically stable. Consequently, liquid crystal compositions containing such a compound are extremely useful as liquid crystals, and are particularly suitable for liquid crystal displays requiring a wide operating temperature range, low voltage driving and a high response speed.
