LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

Disclosed is a liquid crystal composition which can form a nematic phase over a wide temperature range, has a proper level of optical anisotropy, a high negative dielectric anisotropy, and a high specific resistance, preferably a liquid crystal composition in which the optical anisotropy can be increased and the lower limit of the nematic phase can be lowered while retaining the properties mentioned above. Also disclosed is a liquid crystal display element comprising the composition. The liquid crystal composition has a negative dielectric anisotropy and comprises a first component and a second component, wherein the first component comprises a liquid crystalline compound having a terphenyl structure in which one or two hydrogen atoms are substituted by fluorine atoms and the second component comprises a liquid crystalline compound having a phenylene which has hydrogen 2-substituted by fluorine.
