Abstract

The invention relates to a liquid crystal composition which contains a pentafluoropropylene ether end group structure liquid crystal compound. The invention further relates to an application of the liquid crystal composition. The liquid crystal composition is excellent in property, has high dielectric anisotropy and low rotary viscosity, and is applicable to liquid crystal displays with display modes of IPS, FFS (fringe field switching), ADS and the like and TN-TFT (twisted nematic-thin film transistor) liquid crystal displays with low driving voltage.

Description

Technical field [0001] The present invention relates to the field of liquid crystal compositions, in particular to a liquid crystal composition containing a pentafluoropropene ether type liquid crystal compound with an end group structure and its application in the field of liquid crystal display. Background technique [0002] As early as the second half of the nineteenth century, many scholars in various fields including physics, chemistry, and biology have observed the strange phenomena of some compounds that change with temperature. Later, it was determined that the time when the LCD was officially discovered was 1888. This year, when the Austrian botanist Friedrich Reinitzer was studying the effects of cholesterol on plants, he discovered the first liquid crystal material: cholesterol benzoate (cholesteryl benzoate). More than one hundred years after the discovery of the liquid crystal phenomenon, people have never stopped studying it. [0003] In the early days, O. Wiener et...
