Description
Technical field
The present invention relates to a kind of liquid-crystal composition, in particular to a kind of liquid-crystal composition with suitable optical anisotropy, suitable dielectric anisotropy, wider nematic temperature range, high voltage retention, high resistivity and response speed faster, and comprise the liquid crystal display device of this liquid-crystal composition.
Background technology
Liquid crystal material is at a certain temperature, the mobility not only with liquid but also the mixture of anisotropic organic bar-shaped micromolecular compound with crystal.According to the difference of liquid crystal material character, the liquid crystal material of various phase has been developed mostly in liquid crystal display device.
For liquid-crystal display, possess good chemistry and thermostability, the good stability to electric field and electromagnetic radiation, the liquid crystalline cpd of suitable optical anisotropy, faster response speed and lower threshold voltage and liquid crystal media and meet current needs.Because the mixture of liquid crystal usually used as various ingredients uses, dissolving each other each other between each component, seems particularly important, and according to different battery types and Application Areas, liquid crystal must meet different requirements, as specific conductivity, dielectric anisotropy and optical anisotropy etc., but the shortcoming significantly existed in the prior art is the longer time of response, low resistivity and operating voltage is excessively high, as EP0673986, DE19528106, DE19528107.
Response speed is the important evaluation index of liquid-crystal display, and response speed is excessively slow, and display frame just there will be motion blur phenomenon, therefore requires that liquid-crystal display has fast response speed.In order to improve the response speed of liquid-crystal display, can select and reduce the method such as driving voltage, the quick liquid-crystal composition responded of employing that box is thick, improve type of drive, raising.But no matter adopt which kind of method, always bring the weakening of other performances of liquid-crystal display.As changed type of drive, cost raises, circuit is more complicated often to cause IC to drive; Improve driving voltage, power consumption also can increase thereupon; Reduce box thick, the difficulty of production technique can be increased, cause the defects such as box thickness ununiformity, cause the decline of liquid-crystal display yield.
A series of compounds up to now with liquid crystal Jie phase do not comprise the monomeric compound meeting all these aspects and require, therefore, in liquid crystal material field, need to have the novel liquid crystalline compositions improving performance.Especially, for many type useds, liquid-crystal composition must have suitable wide nematic phase range, suitable specific refractory power, dielectric anisotropy and low temperature storage stability.
The object of this invention is to provide a kind of liquid-crystal composition, it has high, the nematic lower limit temperature of nematic ceiling temperature low (namely transition temperature range is wide); Viscosity is low; Suitable optical anisotropy; Suitable dielectric anisotropy; At least one characteristic in the characteristics such as high-temperature stability is good.Other objects of the present invention are to provide a kind of liquid crystal display device, it is the composition with characteristics such as suitable optical anisotropy, suitable dielectric anisotropy, high-temperature stability are good, and makes liquid crystal display device have time of response short, the characteristic such as display comparison degree is good.
