Abstract
The present invention provides a kind of liquid-crystal composition, comprising：The compound of at least one general formula I；The compound of at least one general formula II 1 and/or II 2；The compound of at least one general formula III；The compound of at least one general formulae IV.The liquid-crystal composition of the present invention has at least one of the characteristics such as larger dielectric anisotropy, larger optical anisotropy, suitable clearing point and low viscosity characteristic, suitable for liquid crystal display device.The present invention also provides the liquid crystal display device comprising the liquid-crystal composition.
Description
Technical field
It is more particularly to a kind of that there is larger optical anisotropy, larger Jie the present invention relates to a kind of liquid-crystal composition
Electrical anisotropy, suitable clearing point and liquid-crystal composition compared with low viscosity and the liquid crystal display for including the liquid-crystal composition
Part.
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.PM (passive matrix, passive-matrix) types and AM (active are divided into according to the type of drive of element
Matrix, active-matrix) type.PM points are the static state type such as (static) and multichannel (multiplex).AM points are TFT (thin
Film transistor, thin film transistor (TFT)), the class such as MIM (metal insulator metal, metal-insulator-metal)
Type.The type of TFT has non-crystalline silicon (amorphous silicon) and polysilicon (polycrystal silicon).The latter according to
Manufacturing process is divided into high temperature modification and low form.Liquid crystal display element according to the type of light source be divided into the reflection-type using natural light,
Infiltration type using backlight and the semi-transmission type using two kinds of light sources of natural light and backlight.
The general characteristic of 1 composition of table and AM elements
| NO. | The general characteristic of composition | The general characteristic of AM elements |
| 1 | Nematic wide temperature range | Workable wide temperature range |
| 2 | Viscosity is small | Response time is short |
| 3 | Optical anisotropy is appropriate | Contrast is big |
| 4 | Positive or negative property dielectric constant anisotropy is big | Critical voltage is low, and consumption electric power is small, and contrast is big |
| 5 | Resistivity is big | Voltage retention is big, and contrast is big |
| 6 | To ultraviolet and thermostabilization | Long lifespan |
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
Preferably less than it is equal to -10 DEG C.The viscosity of composition is associated with the response time of element.It is dynamic in order to show in the component
Draw, the response time of preferably element is short.Therefore, the viscosity of preferably composition is small, and group when preferably temperature is low
The viscosity of compound is small.
The optical anisotropy of composition is associated with the contrast of element.In order to make the contrast of liquid crystal display element most
Bigization, can (Δ n) and the product value (Δ n*d) of the thickness (d) of liquid crystal layer be set as by the optical anisotropy of liquid-crystal composition
The mode of fixed value is designed.Appropriate product value depends on the species of operating mode.As TN patterns element appropriate value about
For 0.45 μm.During the situation, for the less element of thickness of liquid crystal layer, the preferably big combination of optical anisotropy
Thing.
Liquid crystal display element containing the appropriate liquid-crystal composition of optical anisotropy can increase contrast.
Liquid crystal display element containing the small liquid-crystal composition of viscosity can shorten the response time.When liquid crystal display element
Response time in short-term, is applicable to animation and shows.In addition, when liquid-crystal composition is injected into the liquid crystal cell of liquid crystal display element,
Injection length can be shortened, it is possible to increase workability.
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 nematic phase temperature model
Enclose that not wide enough, clearing point is relatively low, viscosity is higher, optical anisotropy is not big enough, dielectric anisotropy is relatively low, ultraviolet and high temperature is steady
It is qualitative it is poor, voltage retention is low, to be mixed into have compared with large optical anisotropic, suitable dielectric anisotropy, better stability
And preferably the composition of contrast helps less, to directly result in the adverse consequences such as contrast is low, response speed is slow.
Therefore, it is necessary to a kind of liquid-crystal composition, it is with big optical anisotropy；Higher clearing point；Low viscosity；
Appropriate dielectric anisotropy；At least one of the characteristics such as high contrast characteristic.
The content of the invention
There is larger optical anisotropy, larger dielectric anisotropy, suitable the object of the present invention is to provide a kind of
Clearing point and at least one of the characteristic such as relatively low viscosity characteristic liquid-crystal composition.
The present invention other purposes be to provide a kind of liquid crystal display element, it includes with larger dielectric anisotropy,
Larger optical anisotropy, the liquid-crystal composition compared with characteristics such as low viscosities so that liquid crystal display element has high contrast, fast
Response speed, superior power saving performance.
