Abstract
The technical problem to be solved in the present invention is to provide a kind of composition, it is that Δ ε is positive composition, liquid crystalline phase with wide temperature range, viscosity is small, favorable solubility when low temperature, and resistivity, voltage retention are high, heat, light are stablized, it is furthermore that by using the composition, to be provided with good yield rate, display quality is excellent, is not likely to produce the liquid crystal display element that burn-in, drop impression etc. show undesirable IPS types, TN types etc..The present application provides a kind of composition, it contains the compound represented by one kind or two or more general formula (i), the compound represented by one kind or two or more general formula (ii) and the compound represented by one kind or two or more general formula (L 1), while offer has used the liquid crystal display element of the composition and used the IPS elements or FFS elements of the composition.
Description
Technical field
The present invention relates to the combinations that the dielectric constant anisotropy (Δ ε) useful as liquid crystal display material shows positive value
Object, and use its liquid crystal display element.

Liquid crystal display element is developed to since for clock and watch, electronic calculator for meter device, automobile face
Plate, word processor, electronic notebook, printer, computer, TV, clock and watch, advertising display panel etc..As liquid crystal display side
Formula, representative mode have TN (twisted-nematic) type, STN (super twisted nematic) type, have used hanging down for TFT (thin film transistor (TFT))
Straight orientating type, IPS (plane conversion) type etc..Used in these liquid crystal display elements liquid-crystal composition require to moisture, air,
The environmental stimulis such as heat, light are stablized, and are low in addition, showing liquid crystalline phase within the scope of the temperature as wide as possible centered on by room temperature
Viscosity, and driving voltage is low.Further, in order to be directed to each display element and by dielectric constant anisotropy (Δ ε) or and
(Δ n) etc. is set as optimal value to refractive anisotrop, and liquid-crystal composition is made of several to tens of kinds of compound.
The use of Δ ε is negative liquid-crystal composition in vertical orientation (VA) escope, it is (flat in TN types, STN types or IPS
Convert in face) the use of Δ ε is positive liquid-crystal composition in the horizontal alignment escope such as type.In addition, it was recently reported that by making Δ ε be
Positive liquid-crystal composition vertical orientation when without voltage is applied, and apply transverse electric field, the type of drive to be shown, Δ
ε is that the necessity of positive liquid-crystal composition further increases.On the other hand, low-voltage drive is required in whole type of drive
Dynamic, high-speed response, wide operating temperature range.That is, it is desirable that Δ ε is just and absolute value is big, viscosity (η) is small, nematic phase-is each
To same sex liquid phase transition temperature (Tni) height.In addition, it is necessary to according to the setting of Δ n and product, that is, Δ n × d of cell gap (d),
Combining unit gap and the Δ n of liquid-crystal composition is adjusted to range appropriate.In addition, by used for liquid crystal display element in TV etc.
When purposes, pay attention to high-speed response, therefore it is required that the liquid-crystal composition that rotational viscosity (γ 1) is small.
As the composition for the liquid-crystal composition for being intended to high-speed response, such as it will be positive liquid-crystalization as Δ ε to disclose
The compound and be applied in combination as (B) that Δ ε is neutral liquid-crystal compounds that the formula (A-1) of conjunction object, (A-2), (A-3) are indicated
Liquid-crystal composition (patent document 1 to 4).
[changing 1]
On the other hand, as the purposes of liquid crystal display element expands, application method, manufacturing method also show big change
Change.In order to cope with these variations, it is desirable that optimized to the characteristic other than previously known basic physical properties value.That is,
It is also practical and make about its size with using the liquid crystal display element of liquid-crystal composition that VA types, IPS types etc. is widely used
With the display element of ultra-large type sizes more than 50 types.With the enlargement of substrate size, note of the liquid-crystal composition to substrate
Enter method also to become with instillation (ODF from previous vacuum impregnation:One Drop Fill) method become method for implanting master
The problem of stream, drop impression when liquid-crystal composition is added dropwise to substrate causes display quality to reduce, emerges out.Further, passing through
In the liquid crystal display element manufacturing process that ODF methods carry out, need the size according to liquid crystal display element that optimal liquid crystal note is added dropwise
Enter amount.If deviation of the injection rate apart from optimal value becomes larger, refractive index, the driving electric field of the liquid crystal display element being pre-designed
Balance be destroyed, it is bad that the displays such as the generation of spot, contrast be bad occur.Especially with respect in the smart mobile phone of nearest prevalence
Common small-sized liquid crystal display element will be controlled apart from the deviation of optimal value one since optimal liquid crystal injection rate is few
It is inherently highly difficult to determine in range this.Therefore, it in order to keep the high finished product rate of liquid crystal display element, needs for example for dropping liquid
Pressure change drastically, the influence of impact in the Dropping feeder generated when brilliant are small, can continue dropping liquid long-term and stably
Brilliant performance.
So, the liquid crystal combination used in the driven with active matrix liquid crystal display element by drivings such as TFT elements
In object, it is desirable that carry out following exploitation：Maintain high speed response property etc. as characteristic, the performance required by liquid crystal display element,
And in addition to the previous high resistivity value just paid attention to or high voltage holding ratio, stablizing in this way to outside stimulus such as light, heat
Characteristic other than, it is also contemplated that the manufacturing method of liquid crystal display element.

It is found that the application composition can realize the value of required Δ n in a wide range, the liquid with wide temperature range
Crystalline phase, viscosity is small, and favorable solubility when low temperature, resistivity, voltage retention are high, stablizes to heat, light, be not likely to produce burn-in,
The display such as drop impression is bad, additionally by the application composition is used, can produce FFS types, IPS types, TN with good yield rate
The liquid crystal display element of type etc..
