Technical field
The present invention relates to a kind of liquid-crystal composition, there is suitable optical anisotropy, suitable more particularly to one kind
Dielectric anisotropy, appropriate clearing point, the liquid-crystal composition of low threshold voltage and faster response speed and its in liquid
Application in crystal display.
Background technology
For liquid crystal display element, PC (phase change, phase transformation), TN are divided into according to the display pattern of liquid crystal
(twist nematic, twisted-nematic), STN (super twisted nematic, super twisted nematic), ECB
(electrically controlled birefringence, electrically conerolled birefringence), OCB (optically compensated
It is bend, optical compensation curved), IPS (in-plane switching, coplanar transformation), (vertical alignment, hang down VA
Straight orientation) etc. type.Liquid crystal display element is divided into the reflection-type using natural light, the transmission using backlight according to the type of light source
Type and the semi-transmission type using two kinds of light sources of natural light and backlight.
Liquid crystal material is needed with appropriate high dielectric anisotropy, optical anisotropy and good low temperature intersolubility
And heat endurance.In addition, liquid crystal material should also have low viscosity and short response time, low threshold voltage and high contrast.Root
The each to performance indicator of composition is further illustrated according to commercially available liquid crystal display element.Nematic temperature range and element
Operating temperature range is associated.Nematic ceiling temperature is preferably more than or equal to 70 DEG C, and nematic lower limit temperature

The viscosity of compound is small.
Single liquid-crystal compounds is generally difficult to play its characteristic, and usually it is mixed with other plurality of liquid crystals compounds and is matched somebody with somebody
Composition is made.In available liquid crystal composition, preferably characteristic can be obtained, but the species compound optical anisotropy
Not big enough, dielectric anisotropy is not big enough, helps less being mixed into the big compositions of Δ n and Δ ε, so as to be unfavorable for being used in small
In the product of box thickness, directly result in that response speed is not fast enough, the liquid crystal combination as disclosed in CN101796162A, CN1475547A
Thing, in varying degrees with disadvantages mentioned above.
Therefore, it is necessary to a kind of liquid-crystal composition, it is with nematic ceiling temperature is high, nematic lower limit temperature is low
(i.e. transition temperature range is wide)；Low viscosity；Suitable optical anisotropy；Suitable dielectric anisotropy；Good is ultraviolet
The stability of line；At least one of the characteristics such as good low temperature storage stability characteristic.
The object of the present invention is to provide a kind of liquid-crystal composition, it is low with viscosity；Threshold voltage is low and low temperature stores
The characteristics such as stability height.Other objects of the present invention are to provide a kind of liquid crystal display element, its be have suitable optics respectively to
Different in nature, suitable dielectric anisotropy, appropriate clearing point, viscosity is low, threshold voltage is low and low temperature storage stability height etc.
The composition of characteristic, and cause the characteristics such as liquid crystal display element response time short, the big, long lifespan of contrast.
The content of the invention
It is an object of the invention to provide a kind of liquid-crystal composition, it possesses, and nematic temperature range is wide, viscosity is low, threshold value
The characteristics such as voltage is low, low temperature storage stability height, the liquid crystal display element comprising the liquid-crystal composition have fast response time, low
The advantages that warm storage stability is high.The liquid-crystal composition have suitable optical anisotropy, suitable dielectric anisotropy,
Appropriate limpid dot characteristics, suitable for low temperature environment.
