Description

There is liquid-crystal composition and the application thereof of negative dielectric anisotropic
Technical field
The present invention relates to a kind of liquid-crystal composition, in particular to a kind of, there is suitable negative dielectric anisotropic, suitable optical anisotropy, lower viscosity, the liquid-crystal composition of wider nematic phase range and the application in VA, MVA, PVA, PSVA, IPS or TFT mode LCD thereof.
Background technology
In liquid crystal display device, classification based on the operating mode of liquid crystal has: phase transformation (phase change, hereinafter referred to as PC), twisted nematic (twisted nematic, hereinafter referred to as TN), STN Super TN (super twisted nematic, hereinafter referred to as STN), electrically conerolled birefringence (electrically controlled birefringence, hereinafter referred to as ECB), optical compensation curved (optically compensated bend, hereinafter referred to as OCB), transverse electric field switch type (IPS), vertical transverse type (VA) etc.Classification based on the type of drive of device has: passive-type matrix (passive matrix, hereinafter referred to as PM) and AM.PM is divided into static state (static) and multiplex (MUX) (multiplex) etc., and AM is divided into thin film transistor (thin film transistor, hereinafter referred to as TFT), metal-insulator-metal (metal insulator metal, MTM) etc.The classification of TFT has non-crystalline silicon (amorphous silicon) and polysilicon (polycrystal silicon).The latter can be divided into high temperature modification and low temperature modification according to the difference of manufacturing step.Classification based on light source have utilize the reflection-type of natural light, utilize backlight (black light) penetrating type, utilize the semi penetration type of both natural light and backlight.
Current, vertical orientation type (VA) indicating meter, more and more known by people, be applied in widely on TV, watch-dog, Vehicle-carrying type steel indicating meter, and the liquid crystal media be mated needs specific customization.Such as, liquid crystal media should have suitable negative dielectric anisotropic, suitable optical anisotropy, wide nematic temperature range, less viscosity and responding faster.For the liquid-crystal display of active array addressing, liquid crystal media also needs to have high voltage and keeps ratio, and good light, thermostability.Especially, for the indicating meter being used in Vehicle-carrying type steel and other outdoor uses, especially need to have wider nematic temperature range and time of response faster.
But the properties of liquid crystal media is conflicting, available liquid crystal medium cannot have above-mentioned performance simultaneously.For the indicating meter being used in Vehicle-carrying type steel and other outdoor uses, while the nematic temperature range ensureing non-constant width, need suitable negative dielectric anisotropic, suitable optical anisotropy, viscosity little as far as possible and good light, thermostability.Liquid-crystal composition disclosed in Chinese patent application publication number CN101679867A, although there is enough wide nematic phase upper temperature limit, viscosity is relatively large, responds fast not.
Well-known, the optical delay of the liquid crystal layer of VA display is the wavelength of 1/2, distortion is shown, even be operated in the first mnm. also require that the optical delay of liquid crystal layer is close to an all-optical wavelength, the thick meeting of box that the optical delay amount of visible VA pattern determines VA liquid-crystal display is less than twisted mode.In actual use, retardation design (i.e. Δ n*d) of the liquid crystal display device of VA pattern generally can be a bit larger tham theoretical value, and its value is at about 300nm, and the thick general control of its box is at about 3 ~ 4 μm.And less box thick (3 ~ 3.5 μm) although can bring responds faster, its more difficult control in production, the yield of the liquid crystal cell produced is lower, and comprehensive cost is higher.Comparatively speaking, larger box thick (3.5 ~ 4 μm) can better production control technique, is more conducive to large-scale production application.Therefore, the negative liquid crystal composition of a series of low-refraction of urgent demand, low negative dielectric anisotropic, low viscosity, wide nematic phase range.The liquid-crystal composition of negative dielectric anisotropic provided by the invention, can meet the characteristic of low-refraction, low negative dielectric anisotropic, low viscosity, wide nematic phase range, be applicable to VA, MVA, PVA, PSVA, IPS or TFT mode LCD.
