Description
Technical field
The present invention relates to a kind of liquid-crystal composition and its liquid crystal display device, more particularly to it is a kind of have larger dielectric respectively to
Different in nature, higher clearing point, compared with low viscosity, higher contrast and appropriate optically anisotropic liquid-crystal composition and comprising described
The liquid crystal display device of liquid-crystal composition.
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 | Rotary 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, and fusing point is lower, and clearing point is higher, then the nematic temperature range of liquid crystal is wider.On nematic
Limit temperature (being increased to the temperature of clearing point, Cp) and be preferably more than or equal to 70 DEG C, and nematic lower limit temperature (drops
The low temperature to fusing point, Tc) preferably less than it is equal to -10 DEG C.The rotary viscosity of composition is related to the response time of element
Connection.In order to show animation in the component, the response time of preferably element is short.Therefore, the rotation of preferably composition is glued
Spend small, and the rotary viscosity of composition is small when preferably temperature is low.
Comparatively ideal AM elements are that have that workable wide temperature range, response time are short, contrast is big, critical voltage
The characteristics such as low, voltage retention is big, long lifespan, preferably the response time be even shorter than 1 millisecond.Therefore, the spy of composition
Preferably nematic ceiling temperature is high, nematic lower limit temperature is low, rotary viscosity is small, optical anisotropy is big for property,
Dielectric constant anisotropy is big, resistivity is big, to high, stability height to heat of stability of ultraviolet etc..
Nematic temperature range is related with using the temperature range of liquid crystal display element, contains nematic temperature range
The liquid crystal display element of wide liquid-crystal composition, it can expand the temperature range used as liquid crystal display element.
Liquid crystal display element containing the big liquid-crystal composition of optical anisotropy can increase the ratio between contrast.
The liquid crystal display element of the big liquid-crystal composition of absolute value containing dielectric anisotropy can reduce basic voltage
Value, reduce driving voltage, and can further reduce consumption of electric power.
Liquid crystal display element containing the small liquid-crystal composition of rotary viscosity can shorten the response time.When liquid crystal display member
The response time of part in short-term, is applicable to animation and shows.In addition, inject liquid-crystal composition into the liquid crystal cell of liquid crystal display element
When, 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.So we are badly in need of a kind of chemical combination for having the advantages that above-mentioned liquid-crystal composition, being referred in CN1249736A
Thing is formulated into liquid-crystal composition, can obtain preferably characteristic, its structure is as follows：
But the species compound dielectric anisotropy is not big enough, optical anisotropy is not big enough, to being mixed into Δ n and Δ
Composition big ε helps less, so as to be unfavorable in the product of capsule thickness, it is not fast enough to directly result in the product response.
The object of the present invention is to provide a kind of liquid-crystal composition, and it is high, nematic that it possesses nematic ceiling temperature
In the characteristics such as lower limit temperature is low, rotary viscosity is small, optical anisotropy is big, dielectric anisotropy is big, low temperature storage stability height
At least one characteristic.Other objects of the present invention are to provide a kind of AM elements, especially with optical anisotropy is big, dielectric
The composition for the characteristics such as anisotropy is big, low-temperature stability is high, and the AM elements have that the response time is short, use temperature range
Extensively, the characteristic such as long lifespan.
The content of the invention
The object of the present invention is to provide a kind of liquid-crystal composition, it has wider nematic temperature range, larger dielectric
The characteristics such as anisotropy, larger optical anisotropy, higher clearing point, low rotary viscosity, good low-temperature stability
At least one of characteristic.
The present invention other purposes be to provide a kind of liquid crystal display element, it includes with larger dielectric anisotropy,
Larger optical anisotropy, high voltage retention, high clearing point, wide nematic temperature range, the stabilization to low temperature
Property the characteristic such as high, relatively low rotary viscosity composition so that liquid crystal display element has in dielectric anisotropy larger, clearing point
While higher, ensure faster response, and low-temperature phase height is low, and intersolubility is good, good reliability, can be used in capsule thickness
In TFT or IPS liquid crystal display elements.
