Abstract
The present invention relates to a liquid crystal composition having positive dielectric anisotropy, large dielectric anisotropy, low viscosity, and also high light stability at the same time. The present invention also makes it possible to provide a liquid crystal display element having high light stability and no ghosting or display defects at the same time that low-voltage driving, high contrast, and high-speed response are obtained.

Description
Technical field
The present invention relates to a kind of dielectric constant anisotropy useful as electrooptics liquid crystal display material (Δ ε) shows just
The nematic liquid crystal composition of value.
Background technology
Liquid crystal display cells are used at the various mensuration machines with clock, calculator as representative, automobile panel, word
Manage mechanical, electrical sub- notepad, printer, computer, TV, clock, advertising display panel etc..As liquid crystal display mode, its representative
The mode of property has to be using TN (twisted nematic) type, STN (STN Super TN) type, the vertical orientated of TFT (thin film transistor (TFT))
The VA types of feature or IPS (transverse electric field effect) type/FFS types for being characterized with horizontal alignment etc..To for these liquid crystal displays
The liquid-crystal composition that element is used, it is desirable to relative to external factor such as water, empty air and heat, light be stable, furthermore, it desired to room
Liquid crystalline phase, low viscosity are represented in temperature range as wide as possible centered on temperature, and driving voltage is low.And then liquid-crystal composition, it is
Coordinate optimal dielectric constant anisotropy (Δ ε) relative to each display element and/or make refractive anisotrop (Δ
Etc. n) become optimal value, be made up of the compound of several to tens of kinds.
Vertical orientated escope is negative liquid-crystal composition using Δ ε, the horizontally oriented type such as TN types, STN types or IPS types
Display is positive liquid-crystal composition using Δ ε.In recent years, also report has and makes Δ ε be positive liquid-crystal composition without applied voltage
When it is vertical orientated, by applying IPS types/FFS types electric field the type of drive that shows, and Δ ε be positive liquid-crystal composition must
The property wanted further is lifted.On the other hand, in whole type of drive, low voltage drive, high-speed responsive, wide work have been required
Make temperature range.I.e., it is desirable to have Δ ε for just and absolute value is big, viscosity (η) is little, nematic phase-isotropic liquid phase in version temperature
Degree (Tni) high.Further it is necessary to be the setting of Δ n × d according to the product of Δ n and cell gap (d), engagement unit gap and by liquid crystal
The Δ n of composition is adjusted in appropriate scope.Additionally, when liquid crystal display cells are applied to into TV etc., due to paying attention at a high speed should
The property answered, therefore require the little liquid-crystal compositions of γ 1.
It is that positive liquid-crystal compounds i.e. formula (A-1) or the compound shown in formula (A-2) are used as liquid to disclose using Δ ε
The liquid-crystal composition (patent document 1 is to patent document 4) of the constituent of crystal composite, but these liquid-crystal compositions are not carried out
Substantially low viscosity.
On the other hand, disclose a kind of with regard in order to improve the performance of liquid crystal display, will be with fluorine atom or fluoroform
Epoxide as polar group beyond, (patent document 5 is to special for the invention of the compound with various groups and the composition containing it
Sharp document 18).However, it is must to realize substantially low viscosity that these liquid-crystal compositions similarly still cannot be said.
In order to the low viscosity of high-speed responsive it is outside the pale of civilization, for liquid-crystal composition, for the high life of liquid crystal display cells,
Even if requiring that long-time is used, quality, the also little composition of rheological parameters' change with time of performance.Especially because general low molecule organic compound
The liquid crystal material of thing has the not strong problem of stability for ultraviolet, in order to solve the problem, discloses following invention：Have
Liquid-crystal composition containing additive (patent document 19) in the compound of pyrimidine ring, there is the dielectric of specific compound normal in combination
Number anisotropy is the liquid-crystal composition containing additive (patent document 20) in negative liquid-crystal composition.
In addition, used using the liquid crystal display cells of liquid-crystal composition, so that VA (vertical orientated) types or IPS are (laterally
Field effect) type etc. is widely used, and its size also reaches the practical of ultra-large type size display elements more than 50 types.With
The maximization of substrate size, liquid-crystal composition to the method that substrate injects also becomes that injection is added dropwise from previous vacuum impregnation
(ODF：OneDropFill) method becomes the main flow (with reference to patent document 21) of method for implanting, and liquid-crystal composition is added dropwise in substrate
When the problem surfaces that trace causes display quality to decline are added dropwise, show the bad yield penalty for causing liquid crystal display cells
Situation becomes problem.In addition, when adding antioxidant, the additive such as light absorber in liquid-crystal composition, this finished product sometimes
Rate deteriorates also is a problem very much, further, in addition to this dropwise addition trace, if liquid crystal display cells long-time is same continuously display,
The problem for turning off display and the still continuously display phenomenon for being referred to as burn-in of its display is then also produced sometimes.Seek to develop
Have the characteristics such as contrast, the answer speed of the key property as liquid crystal display cells concurrently and be difficult to burn-in, trace etc. is added dropwise
The liquid crystal display cells of the reliability of image quality quality, seek exploitation to be adapted to their liquid-crystal composition.
