Description
Technical field
The present invention relates to a kind of liquid-crystal composition, particularly a kind ofly there is suitable optical anisotropy, suitable dielectric is eachThe liquid-crystal composition of anisotropy, higher clearing point, faster response speed and good low temperature storage stability, and bagContaining the liquid crystal display device of this liquid-crystal composition.
Background technology
Liquid crystal material is at a certain temperature, not only has the mobility of liquid but also have the anisotropic organic bar-shaped of crystalThe mixture of micromolecular compound. Liquid crystal material extensively should because of its feature with optical anisotropy and dielectric anisotropyFor device liquid crystal display cells such as electronic calculator, automobile instrument, television set, computers.
Liquid crystal material is divided by phase transition temperature, can be divided into normal temperature liquid crystal (phase transition temperature scope is :-10 DEG C～60 DEG C) and wide temperature liquidBrilliant (phase transition temperature scope is :-20 DEG C～70 DEG C), with the liquid crystal display of the liquid crystal material manufacturing of different phase transition temperatures, itsApplication site is different. Along with the continuous expansion of liquid crystal display device range of application, the operating temperature range of people to deviceAlso have higher requirement, to adapt to various severe environments for use. In order to expand the working range of liquid crystal display, liquidBrilliant display material also needs there is wide nematic temperature range, all can keep good wanting of showing to meet in various environmentAsk.
For liquid crystal display, possess good chemistry and heat endurance, good stable to electric field and electromagnetic radiationLiquid-crystal compounds and the liquid crystal media of property, suitable optical anisotropy, faster response speed and lower threshold voltage areMeet current needs. Because liquid crystal uses usually used as the mixture of various ingredients, dissolving each other each other between each component is aobviousParticularly important, and according to different battery types and application, liquid crystal must meet different requirements, as electrical conductivity,Dielectric anisotropy and optical anisotropy etc., but the shortcoming significantly existing is in the prior art the response time of growing,Low resistivity and operating voltage are excessively high, as EP0673986, DE19528106, DE19528107. In addition, low temperatureStorage stability is poor is also the defect of existing many liquid crystal materials, as WO9732942A1.
Disclosed a series of compounds with liquid crystal Jie phase do not comprise the list that meets all these aspects requirements up to nowBody compound, therefore, in liquid crystal material field, need to have the novel liquid crystalline compositions of improving performance. Especially, forMany application types, liquid-crystal composition must have suitable wide nematic phase range, suitable refractive index, dielectric respectively toThe opposite sex and low temperature storage stability.
The object of this invention is to provide a kind of have higher clearing point, low kinematic viscosity, wide nematic phase range, low temperature storageThe liquid-crystal composition of good stability, described liquid-crystal composition can be applicable in liquid crystal cell, while making this liquid crystal cell have responseBetween short, the characteristic such as reliability high and low temperature memory property is good.
The response time of liquid crystal is proportional to the coefficient of viscosity of liquid crystal. The coefficient of viscosity of liquid crystal is larger, points to and vows in outfield or selfUnder the effect of elastic force, the time that is converted to another state from a state is longer, and liquid crystal is just slower as the speed of photoswitch.
