Description

Liquid-crystal composition and use its liquid crystal display device
Technical field
The present invention relates to as useful dielectric constant anisotropy (Δ ε) display of liquid crystal display material on the occasion of nematic liquid crystal composition and use its liquid crystal display device.
Background technology
Liquid crystal display device is the various metering equipments, instrument panel for motor vehicle, word processor, electronic notebook, printer, computer, TV, clock and watch, advertising display panel etc. that are used in headed by clock and watch, counter.As liquid-crystal display mode, its representative person has TN (twisted-nematic) type, STN (supertwist is to row) type, uses the vertical orientating type, IPS (plane conversion) type etc. of TFT (thin film transistor).Liquid-crystal composition for these liquid crystal display device is required to stablize for external stimuluses such as moisture, air, heat, light, and shows mesomorphic phase in the as far as possible wide temperature range centered by room temperature, low viscosity and driving voltage is low.Moreover liquid-crystal composition in order to make with regard to each display element dielectric constant anisotropy (Δ ε), refractive anisotrop (Δ n) etc. for just when, and to be made up of to tens of kinds of compounds several.
Vertical orientated (VA) escope uses Δ ε to be negative liquid-crystal composition, and the horizontal alignment escope of TN type, STN type or IPS (plane conversion) type etc. then uses Δ ε to be positive liquid-crystal composition.In addition, also reporting without making Δ ε be that positive liquid-crystal composition is vertical orientated when applying voltage, and by applying transverse electric field to carry out the type of drive shown, having made Δ ε be that the necessity of positive liquid-crystal composition more promotes.On the other hand, in whole type of drive, low voltage drive, high-speed response, wide operating temperature range is all required.That is, require that Δ ε is just and absolute value is large, little, the high nematic phase of viscosity (η)-isotropic liquid phase transition temperature (Tni).In addition, in order to the long-pending Δ n × d as Δ n and unit interval (d) is set in prescribed value, the Δ n engagement unit interval of liquid-crystal composition must be set in suitable scope.In addition the situation high speed responsiveness owing to being applied to TV etc. at liquid crystal display device is paid attention to, so require the liquid-crystal composition that rotational viscosity (γ 1) is little.
As the structure of liquid-crystal composition taking high-speed response as target, having disclosed is such as (B) combination of neutral liquid crystalline cpd and the liquid-crystal composition that uses using the compound represented by the formula (A-1) that is positive liquid crystalline cpd as Δ ε, (A-2) with as Δ ε.As the feature of these liquid-crystal compositions, Δ ε is that positive liquid crystalline cpd has-CF 2o-structure, Δ ε are that neutral liquid crystalline cpd has thiazolinyl, and be widely known by the people in the field of liquid-crystal composition (patent documentation 1 ~ 4).
[changing 1]
On the other hand, the purposes of liquid crystal display device expands, and also observe its using method, manufacture method varies widely.In order to these changes corresponding, and require the characteristic beyond in the past known basic physical properties value to be optimized.That is, use the liquid crystal display device of liquid-crystal composition to widely use VA type, IPS type etc., its size has also used the display element of the ultra-large type size that can realize more than 50 inch.With the maximization of substrate size, the method that liquid-crystal composition injects towards substrate there has also been change, and injection (ODF:OneDropFill) method that changes into from vacuum impregnation in the past dripping is the main flow of method for implanting.But, also make the problem surfaces that drop impression when liquid-crystal composition being dripped to substrate can cause display quality to reduce.
Moreover, manufacture in the operation of liquid crystal display device utilizing ODF method, optimal amount of must dripping according to the size of liquid crystal display device.The deviation of the amount of dripping is with when difference is very large, and the specific refractory power of liquid crystal display device of design in advance, the balance disintegration of driving electric field, can produce that display unevenly to occur, contrast gradient is bad etc. is bad.Especially the small-scale liquid crystal display element mostly used in recently popular smart mobile phone, less owing to measuring under optimal liquid crystal drop, so itself be difficult to by with just when deviation control within the specific limits.Therefore, in order to the fine ratio of product of liquid crystal display device is remained higher, liquid-crystal composition is required to pressure change sharply in the dripping device that such as produces because of time under liquid crystal drop, to impact the impact caused few, through long-time still can be continual and steady drip.
So, for the liquid-crystal composition used in the driven with active matrix liquid crystal display device driven with TFT element etc., require to consider that the manufacture method of liquid crystal display device carries out pursuing the exploitation promoted as the high speed response property required for liquid crystal display device, high resistivity value, high voltage holding ratio or the stability to the outside stimulus such as light, heat.

In the transparency electrode 204 of aforementioned header board, (not containing tinting material) resin liquid that coating column spacing piece is formed.Then, cure this resin layer 402 and make it solidification.Painting photoresist thereon, and prebake is carried out to it.After exposing through mask pattern 401 pairs of photo-resists, carry out video picture by resin layer patterning.Then, peel off photoresist oxidant layer, cure resin layer and complete columnar interval sheet (302,304 of Fig. 1).
The forming position of columnar interval sheet can decide desired position according to mask pattern.Therefore, the sealing area that simultaneously can make liquid crystal display device is interior with both (sealing material coated portion) outside sealing area.In addition, columnar interval sheet preferably so that sealing area quality can not be reduced, the mode be positioned on black matrix" formed.Sometimes will the columnar interval sheet made by photolithography be so utilized to be called intercolumniation partition or light spacing piece.
The material of aforementioned spacing piece can use the mixture of the minus water soluble resins such as PVA-Stilbene azo (Stilbazo) photoresist, multifunctional acrylic monomer, acrylic copolymer, triazole series initiators etc.Or also there is the method making tinting material be scattered in the color resin of polyimide resin.Do not limited especially in the present invention, can according to the liquid crystal used, obtain spacing piece with the phasic property of sealing material with known material.
Thus, after the face becoming sealing area on header board arranges columnar interval sheet, on the face that the sealing material of this backboard contacts, be coated with sealing material (301 in Fig. 1).
The material of sealing material is not limited especially, can be used in epoxy, the light solidified of acrylic acid series, Thermocurable, photo-thermal with the curable resin composition adding polymerization starter in the resin of solidified nature.In addition, in order to control water vapour permeability, Young's modulus, viscosity etc., the earthfill rockfill concrete riprap RCC be made up of inorganics, organism is sometimes added.The shape of these earthfill rockfill concrete riprap RCCs is not limited especially, has spherical, fibrous, amorphous etc.Moreover, spherical, the fibrous separating material with single dispersing footpath can be mixed in order to control unit interval well, or in order to more strengthen and the bonding force of substrate and mix the fibrous material being easy to be wound around with substrate upper process.The diameter of the fibrous material now used expects less than 1/5 ~ 1/10 degree for unit interval, and it is shorter that the length of fibrous material expects comparatively to seal coating width.
In addition, as long as the material of fibrous material can obtain the shape specified, do not limited especially, can suitably be selected the inorganic materials such as the synthon such as Mierocrystalline cellulose, polymeric amide, polyester, glass, carbon.
As the method for coating sealing material, there are print process, apportion design, but the apportion design that preferably usage quantity of sealing material is few.The application place of sealing material usually on black matrix", to make to cause detrimentally affect to sealing area.In order to form the liquid crystal drop lower area (making liquid crystal not spill) of subsequent processing, sealing material being coated with shape and being formed as closed circuit shape.
To drip liquid crystal at the closed circuit shape (sealing area) of the header board being coated with aforementioned seal material.Usual use divider.In order to make the amount of liquid crystal that drips consistent with liquid crystal cells volume, substantially will with the volume that the height of columnar interval sheet is multiplied with sealing surface covered for measuring.But, if the liquid crystal in unit bonding process spills, the optimization of display characteristic and suitably adjust the amount of liquid crystal dripped, then also sometimes make liquid crystal drop upper/lower positions disperse.
Then, by backplane in coating aforementioned seal material and the header board of the liquid crystal that drips.Specifically, aforementioned header board and aforementioned backboard are adsorbed in have electrostatic chuck like that can the platform of mechanism of sorbing substrate, make the 2nd alignment films of header board relative with the 1st alignment films of backboard, be configured at sealing material and the discontiguous position of another substrate (distance).In this condition internal system is reduced pressure.After decompression terminates, confirm the bonding position of header board and backboard and adjust two substrates position (alignment function) simultaneously.After the adjustment of bonding position terminates, make substrate near to the position that the sealing material on header board contacts with backboard.In this condition non-active gas is filled in system, gently opens and reduce pressure and return to normal pressure.Now, make header board and backplane by normal atmosphere, at the height location forming unit interval of columnar interval sheet.To sealing material irradiation ultraviolet radiation, sealing material is solidified in this condition, thus form liquid crystal cells.Then, optionally increase heating process, promote sealing material solidification.In order to strengthen bonding force, the lifting electrical specification reliability of sealing material, mostly increase heating process.
