Description
Technical field
The present invention relates to a kind of liquid-crystal composition, to have bigger optical anisotropy, bigger dielectric each particularly to a kind of
Anisotropy, the liquid-crystal composition of high clearing point and comprise the liquid crystal display device of described liquid-crystal composition.
Background technology
Liquid crystal display cells is that the optical anisotropy utilizing liquid crystal material itself to be possessed and dielectric anisotropy are to carry out work
Make, have been obtained at present being widely applied.Utilize the different characteristic of liquid crystal material and working method, device can be set
Count into various different mode of operation, from the point of view of liquid crystal display cells, be divided into PC (phase according to the display pattern of liquid crystal
Change, phase transformation), TN (twist nematic, twisted-nematic), STN (super twisted nematic, super twisted nematic),
ECB (electrically controlled birefringence, electrically conerolled birefringence), OCB (optically compensated bend,
Optical compensation curved), IPS (in-plane switching, coplanar transformation), VA (vertical alignment, vertical orientation)
Etc. type.Type of drive according to element be divided into PM (passive matrix, passive-matrix) type and AM (active matrix,
Active-matrix) type.PM is divided into the type such as static state (static) and multichannel (multiplex).AM is divided into TFT (thin film
Transistor, thin film transistor (TFT)), the type such as MIM (metal insulator metal, metal-insulator-metal).TFT
Type have non-crystalline silicon (amorphous silicon) and polysilicon (polycrystal silicon).The latter divides according to manufacturing process
For high temperature modification and low form.Liquid crystal display cells is divided into according to the type of light source and utilizes the reflection-type of nature light, utilizes backlight
Infiltration type and utilize nature light and the semi-transmission type of two kinds of light sources of backlight.
In Poor information, general employing passive mode drives, but is as the increasing of quantity of information, display size and display road
Increasing of number, crosstalk and contrast reduce phenomenon and become serious, the most typically use active matrix (AM) mode to drive, mesh
Front more employing thin film transistor (TFT) (TFT) is driven.In AM-TFT element, TFT switch device is two
Dimension grid addresses, in the finite time being on, pixel electrode is charged, becomes the most again cut-off state, directly
To next cycle the most addressed.Therefore, between two addressing periods, it is undesirable to the voltage on pixel changes,
Otherwise the light transmittance of pixel can change, and causes the instability of display.The velocity of discharge of pixel depends on electrode capacity
Resistivity with inter-electrode dielectric.Therefore it is required that liquid crystal material has suitable optical anisotropy value Δ n, (Δ n value is general
0.08～about 0.15), and relatively low threshold voltage, with the driving voltage reduced, reduce the purpose of power consumption.
This kind of liquid-crystal composition has had a lot of document to report, such as foreign patent documents WO9202597, WO9116398,
WO9302153, WO9116399, Chinese patent literature CN1157005A etc..
Consider from the angle of liquid-crystal composition material modulation, the various aspects of performance of material (suitable optical anisotropy value,
High dielectric anisotropy value, low threshold voltage, high voltage retention etc.) between mutually pin down, improve
The performance of aspect is usually associated with the reduction of other aspect performances, and modulation various aspects of performance all suitably liquid-crystal composition is often
Extremely difficult.
Liquid crystal material needs have the highest dielectric anisotropy, optical anisotropy and a higher clearing point, especially,
In order to make liquid crystal display device have more preferable display effect, also require that liquid crystal display device GTG shows better.According to commercially available
Liquid crystal display cells further illustrate each to performance indications of compositions.Nematic temperature range and the work temperature of element
Degree scope is associated.Nematic ceiling temperature is preferably more than or equal to 70 DEG C, and nematic lower limit temperature is preferable
Be less than equal to-10 DEG C.The optical anisotropy of compositions is associated with the contrast of element.In order to make liquid crystal display unit
The contrast of part, can be by the optical anisotropy of liquid-crystal composition (taking advantage of of the thickness (d) of Δ n) and liquid crystal layer than maximizing
Product value (Δ n*d) is set as that the mode of fixed value is designed.Suitable product value depends on the kind of operating mode.Such as TN
The appropriate value of the element of pattern is about 0.45 μm.During this situation, for the element that thickness of liquid crystal layer is less, preferably
It it is the compositions that optical anisotropy is big.
Liquid crystal display cells containing the suitable liquid-crystal composition of optical anisotropy can increase contrast.
The liquid crystal display cells of the liquid-crystal composition that absolute value containing dielectric anisotropy is big can reduce pedestal voltage value, fall
Low driving voltage, and consumption of electric power can be reduced further.
Steepness factor γ is a big influence factor to device parameters, U10、U50、U90Correspond respectively to TN-LCD saturating
The rate variable quantity of mistake is voltage when 10%, 50%, 90%.
It is calculated the U under equilibrium state by the method for free energy density50、U90, draw following relational expression:
γ=(U50-U90)/U90=0.133+0.0266 [(K33/K11)-1]+0.0466 [ln (Δ Δ nd/2 λ]2
When Δ nd/2 λ=1, γ steepest.This condition and light leak minimal conditionUnanimous on the whole, so this condition
The display that available contrast is big, display device light leak is minimum under this condition, steepness is best, and wherein, λ is incident wavelength.
Therefore, γ and the K of liquid crystal material33/K11The most relevant, at the K of TN box33/K11The least, its γ is the least.But at TFT
In display, γ is bigger, and GTG shows better, therefore in TFT shows, and K33/K11Relatively conference is more preferable.
Single liquid-crystal compounds is generally difficult to play its characteristic, generally it is hybridly prepared into other plurality of liquid crystals compounds
Compositions.In available liquid crystal compositions, it is possible to obtain preferably characteristic, but this category combinations thing clearing point is relatively low, viscous
Spend that higher, optical anisotropy is big not, dielectric anisotropy is relatively low, voltage retention is low, has bigger light to being mixed into
Learn anisotropy, suitable dielectric anisotropy, better stability and the preferably compositions of contrast to help not quite, directly to lead
The adverse consequencess such as cause contrast is low, response speed slow, device display effect difference, such as foreign patent documents WO9202597,
WO9116398, WO9302153, WO9116399, Chinese patent literature CN1157005A etc., have in varying degrees
There is disadvantages mentioned above.
Accordingly, it would be desirable to a kind of liquid-crystal composition, it has big optical anisotropy；High dielectric anisotropy；High is clear
Bright spot；Low threshold voltage；Preferably reliability；Good steepness；The characteristics such as good GTG display effect.
