Description
Technical field
It is more particularly to a kind of that there is suitable negative dielectric anisotropic, suitable the present invention relates to a kind of liquid-crystal composition
Optical anisotropy, relatively low viscosity, the liquid-crystal composition of nematic phase range wider and its in VA, MVA, PVA, PSVA, IPS
Or the application in TFT mode liquid crystal display.
Background technology
In liquid crystal display device, the classification of the operating mode based on liquid crystal has：Phase transformation（Phase change, below letter
Claim 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）, light
Learn compensated bend（Optically compensated bend, hereinafter referred to as OCB）, transverse electric field switch type（IPS）, it is vertical horizontal
To type（VA）Deng.The classification of the type of drive based on device has：Passive-type matrix（Passive matrix, hereinafter referred to as PM）And
AM.PM points is static state（static）And multiplexing（multiplex）It is thin film transistor (TFT) Deng, AM points（thin film
Transistor, hereinafter referred to as TFT）, metal-insulator-metal（Metal insulator metal, MTM）Deng.The classification of TFT
There is non-crystalline silicon（amorphous silicon）And polysilicon（polycrystal silicon）.The latter can be according to manufacturing step
Difference and be divided into high temperature modification and low form.Classification based on light source have using natural light reflection-type, using backlight（black
light）Penetrating type, the semi penetration type using both natural light and backlight.
Currently, vertical orientation type（VA）Display is more and more known from, be widely applied to TV, monitor,
On vehicle-mounted class display, and the liquid crystal media coordinated with it needs specific customization.For example, liquid crystal media should have suitable negative Jie
Electrical anisotropy, suitable optical anisotropy, nematic temperature range wide and is responded less viscosity faster.It is right
For the liquid crystal display of active array addressing, liquid crystal media also needs to keep ratio with voltage high, and good light,
Heat endurance.Especially, for using the display that is used in Vehicle-carrying type steel and other open airs, it is especially desirable to it is wider to
Row phase temperature range and faster response time.
However, the properties of liquid crystal media are conflicting, available liquid crystal medium cannot simultaneously have above-mentioned performance.
For using the display used in Vehicle-carrying type steel and other open airs, while the nematic temperature range of non-constant width is ensured,
Need suitable negative dielectric anisotropic, suitable optical anisotropy is viscosity as small as possible and good light, thermally-stabilised
Property.Liquid-crystal composition disclosed in Chinese patent application publication number CN101679867A, although have sufficiently wide nematic phase temperature
The upper limit, but viscosity is relatively large, responds not fast enough.
It is well known that the optical delay of liquid crystal layer that VA shows is 1/2 wavelength, shown for distortion, even work
Make to also require that the optical delay of liquid crystal layer a close to all-optical wavelength in the first minimum, it is seen that the optical delay amount of VA patterns
Determine that the thick meeting of box of VA liquid crystal displays is smaller than twisted mode.In actually used, the delay of the liquid crystal display device of VA patterns
Amount design (i.e. Δ n*d）Theoretical value can be typically slightly larger than, in 300nm or so, its box thickness general control is at 3~4 μm or so for its value.
And less box is thick（3~3.5 μm）Although response faster can be brought, it is more difficult to control in production, produces
The yield of liquid crystal cell is lower, and integrated cost is higher.Comparatively, larger box is thick（3.5~4 μm）Production can preferably be controlled
Technique, more conducively large-scale production application.Therefore, a series of low-refractions of urgent demand, low negative dielectric anisotropic,
The negative liquid crystal composition of low viscosity, nematic phase range wide.The liquid-crystal composition of the negative dielectric anisotropic that the present invention is provided,
Disclosure satisfy that low-refraction, low negative dielectric anisotropic, low viscosity, the characteristic of nematic phase range wide, be applicable to VA,
MVA, PVA, PSVA, IPS or TFT mode liquid crystal display.
