Description

Liquid crystal indicator

Technical field

The present invention relates to liquid crystal indicator.

Background technology

Liquid crystal indicator is currently used to the various household electric appliances headed by clock, computer, sensing equipment, vapour Automobile-used panel, word processor, electronic notebook, printer, computer, television set etc..As liquid crystal display mode, its representative Property mode can enumerate TN (twisted-nematic) type, STN (super twisted nematic) type, DS (dynamic light scattering) type, GH (host and guest) type, IPS (plane conversion) type, OCB (optical compensation birefringence) type, ECB (voltage control birefringence) type, VA (vertical orientated) type, CSH (colored super vertical plane) type or FLC (Ferroelectric liquid Crystals) etc..Additionally, as type of drive, also driving from conventional static state The dynamic generally multiplexing that is changed into drives, and simple matrix mode, is driven with TFT (thin film transistor (TFT)), TFD (thin film diode) etc. recently Dynamic active matrix (AM) mode is becoming main flow.

As shown in figure 1, general color liquid crystal display arrangement is constituted as follows：Each there are 2 pieces of substrates of alignment films (4) (1) possessing between the alignment films and substrate of a side in becomes the transparent electrode layer (3a) and color-filter layer (2) of public electrode, another Possess pixel electrode layer (3b) between the alignment films and substrate of side, these substrates is configured in the way of alignment films are relative to each other, Liquid crystal layer (5) is clamped between them.

Above-mentioned color-filter layer is made up of color filter, color filter by black matrix and red colored layer (R), green colored layer (G), Blue-colored layer (B), and yellow coloring layer (Y) as needed constitute.

The liquid crystal material of liquid crystal layer is constituted, if impurity is remained in material, the electrical characteristic of display device is produced Big impact, therefore the management of height is taken to impurity.Additionally, the material with regard to forming alignment films, it is also known that alignment films are straight Contact liquid crystal layer, produces shadow to the electrical characteristic of liquid crystal layer to liquid crystal layer movement by residuing in the impurity in alignment films Ring, the research about the characteristic of liquid crystal indicator caused by the impurity in aligning film material is being carried out always.

On the other hand, for materials such as the organic pigments used in color-filter layer, also in the same manner as aligning film material, thus it is speculated that Impact to caused by contained impurity to liquid crystal layer.But, because across alignment films and thoroughly between color-filter layer and liquid crystal layer Prescribed electrode, it is taken as that compared with aligning film material, significantly reducing to directly affecting for liquid crystal layer.But, alignment films are generally not Cross the thickness for less than 0.1 μm, transparency electrode is also, the public electrode that color-filter layer side uses in order to improve conductivity, even if Improve also usually less than 0.5 μm of thickness.Therefore, it cannot be said that color-filter layer is placed in completely isolated environment with liquid crystal layer, Via alignment films and transparency electrode, by the impurity contained by color-filter layer, color-filter layer is possible to show the voltage of liquid crystal layer and protects Caused by the reduction of holdup (VHR), the increase of ion concentration (ID), the display such as white macula, orientation inequality, burn-in is bad.

Bad method is shown as what the impurity for solving to constitute contained by the pigment of color filter caused, be have studied and used face The ratio of the extract that material Ethyl formate is obtained is set as below particular value (special to the method for liquid crystal dissolution so as to control impurity Sharp document is 1), by the pigment in specific blue dyed layer controlling method (patent documentation 2) of the impurity to liquid crystal dissolution.So And, big difference is had no using these methods and the impurity in simple reduction pigment, it is in recent years, continuous in the purification techniquess of pigment Under progressive present situation, show that bad improvement is insufficient as solution.

On the other hand, following methods are disclosed：It is conceived to the pass of contained organic impuritiess and liquid-crystal composition in color filter System, represents the difficulty that the organic impuritiess are dissolved to liquid crystal layer with the Hydrophobic Parameters of liquid crystal molecule contained in liquid crystal layer, should The value of Hydrophobic Parameters is set to method more than certain value；From-the OCF of the Hydrophobic Parameters Yu liquid crystal molecule end₃Base is present Dependency relation is set out, and makes more than certain proportion to have-OCF containing liquid crystal molecule end₃The liquid crystal of the liquid-crystal compoundss of base The method (patent documentation 3) of compositionss.

However, being also to be in the citation disclosure to the impact that liquid crystal layer brings with the impurity in suppression pigment The essence of invention, it is not direct with the structure of liquid crystal material to the structure of the color material such as dye pigment used in color filter Relation is studied, and the solution of the bad problem of display of the liquid crystal indicator of unrealized High Level.

(super small angle X ray scattering profile)

The volume fraction for determining the particle of below 1000nm can be by parsing based on the extra small of super X-ray small angle scattering method Angle X-ray scatters profile and obtains.

Specifically, which is the assay method with following operations：Operation (A), based on super X-ray small angle scattering method, surveys Determine the super small angle X ray scattering profile (determining scattering profile) of organic pigment；Above-mentioned organic pigment is assumed to half by operation (B) The spherical particle of footpath R and there is the variation of particle diameter distribution, by simulation, by the radius R for assuming₁Value and the standardization point for assuming Scattered value obtains theoretical scattering profile；Operation (C), scatters profile to the theory and said determination scattering profile carries out curve fitting, Obtain above-mentioned theory scattering profile the residual sum of squares (RSS) Z value of profile is scattered with said determination；And operation (D), add new half Footpath R_n+1Value (n be integer, R_n＜ R_n+1) and respective hypothesis standardization dispersion value, set multiple particle diameter distribution models, weight Multiple n above-mentioned operation (B) to (C), until the residual sum of squares (RSS) Z value obtained by operation (C) is less than 2%, by above-mentioned reason By the result that scattering profile and said determination scattering profile carry out curve fitting, the primary particle diameter and senior grain of organic pigment are determined The mean diameter of son, standardization dispersion value, at least one in volume fraction.

Super X-ray small angle scattering method (Ultra-Small Angle X-ray Scattering：USAXS) refer to, not only Measure angle of scattering is the little angular zone of 10 ° of 0.1 ° of ＜ (2 θ) ＜ and surpasses as 0.1 ° of 0 ° of ＜ (2 θ) while also determining The method of the scattering/refraction of the undiscipline that little angular zone occurs.In small angle X ray scattering method, if there is 1～100nm in material The different region of the electron density of left and right size, then can utilize electron density difference measure the careless and sloppy scattering of X-ray；And at this In super X-ray small angle scattering method, if the different region of the electron density that there is 1～1000nm or so size in material, profit The careless and sloppy scattering of X-ray is measured with the electron density difference.Based on the angle of scattering and scattering strength, the grain of measuring object is obtained Footpath.

The major technique of the super X-ray small angle scattering method of realization is reached by 2 kinds of following technologies：It is incident using reducing The wavelength length of X-ray, beam diameter reducing the advanced optical system control technology of the backscatter intensity of extra small angular zone, to the greatest extent May make to increase the part little so as to accurately determine angle of scattering from the i.e. so-called camera length of distance of sample to detector. Using the midget plant of use for laboratory, mainly reached by former technique.

Additionally, as the program of particle diameter distribution is obtained by low-angle scattering of X-rays curve, preferably using NANO- The program such as solver (Co., Ltd. Neo-Confucianism's system) or GIFT (PANalytical systems).

In the case of determining the particle diameter physics value of epsilon-type phthalocyanine pigment, if the incident X-rays of X-ray scattering device is bright Spend for 10⁶Brilliance(photons/sec/mm²/mrad²/ 0.1%bandwidth) more than, then can determine and sufficiently dissipate Penetrate intensity, preferably 10⁷More than Brilliance.The substrate of film is easy absorption X-ray in the case of glass etc., therefore is entered The brightness for penetrating X-ray is substantially not enough, thus, in order to accurately determine the primary particle and senior particle of epsilon-type phthalocyanine pigment Mean diameter, standardization dispersion value, volume fraction, the brightness of incident X-rays are preferably 10¹⁶More than Brilliance, more preferably For 10¹⁸More than Brilliance.

In order to obtain 10¹⁶The high brightness X-ray soures of more than Brilliance, it is possible to use large-scale radiating light facility, for example The light sources such as the SPring-8 of Bingku county, the Photon Factory in Ibaraki county.In such equipment, can be arbitrary by selecting Camera length is setting purpose scattering region.Additionally, in order to obtain sufficient scattering strength, in order to prevent specimen fails and then For Protective Detector, by light incident side using the baffle of the several metal for being referred to as attenuator or when will expose Between arbitrarily adjusted at 0.5～60 second or so, most suitable condition determination can be selected for extensive purpose.Attenuator Thin film of such as Au, Ag, molybdenum etc. can be enumerated.

As the concrete steps for determining, first, in operation (A), color filter is arranged at into commercially available refraction of X-ray device Specimen mounting, after sample bench etc., determine scattering strength I of the angle of scattering (2 θ) less than each angle of scattering (2 θ) of 10 ° of scopes, so as to survey Determine small angle X ray scattering profile (determining scattering profile).

Substrate by the extra small angle scattering device of the utilization radiating light used in the case of the film of glass is, with following works Industry is used as operation (A)：Using bicrystal beam splitter, the white light monochrome taken out is made from the circular accelerator for being referred to as storage rings Change, with the wavelength in X-ray region (for example) as radiographic source, the film being arranged on sample bench is incident in, using two dimension inspection Surveying device carries out certain hour exposure to scattered light, the scattering profile obtained with concentric circles is averagely turned to one-dimensional, is converted to scattered Scattering strength I of the firing angle (2 θ) less than each angle of scattering (2 θ) of 10 ° of scopes, obtains small angle X ray scattering profile and (determines scattering wheel It is wide).

Next, in operation (B), by the measure scattering profile for obtaining, it is assumed that spherical particle of the organic pigment for radius R And there is the irregular of particle diameter distribution, it is simulated using commercially available analysis software, by the radius R for assuming₁Value and assume mark Standardization dispersion value obtains theoretical scattering profile.

In general, in the case of the poor region of the electron density that there is Δ ρ (r) in material, scattering strength I can be as following Formula (1) is carried out approximately like that.

[number 2]

In above-mentioned formula (1), q represents scattering vector, and V represents the region of volume integral, it is meant that total material is accumulated Point.Additionally, F (q) is form factor, S (q) is structure factor, in the presence of particle is unordered in material, become S (q)= 1.Additionally, scattering vector q is represented by following formula (2).

[number 3]

In above-mentioned formula (2), λ is the wavelength of X-ray, and 2 θ are angle of scatterings.In above-mentioned formula (1), if it is R that particle is radius Spherical, then form factor F (q) is represented by following formula (3).

[number 4]

Therefore, according to above-mentioned formula (1), (2) and (3), if it is assumed that the value of the radius R for assuming, calculate form factor F (q), it becomes possible to describe scattering strength I.However, above-mentioned scattering strength I has only assumed that the particle in material has certain certain The situation of size (radius R is certain).And in actual material, particle exist with certain size be it is rare, particle Size generally there are irregular (particle diameter distribution irregular) to a certain degree.Additionally, in the present invention, as purpose is correct and high Precision ground determines the particle diameter distribution with the irregular organic pigment of such particle diameter distribution, thus, it has been necessarily required to particle diameter distribution Irregular hypothesis.

Irregular if there is the particle diameter distribution, then above-mentioned scattering strength I is by dissipating that the particle with various sizes is produced Penetrate superposition and be given.The public affairs used in statistics can be used in the distribution function used in the irregular hypothesis of particle diameter distribution The distribution function known, it is contemplated that the particle diameter distribution in actual material it is irregular, preferably use Γ distribution functions.The Γ is distributed letter Number is represented by following formula (4).

[number 5]

Here, R₀It is the mean radiuss of spherical particle, M is particle diameter distribution range parameter.So, if set to can assume that Particle diameter distribution in material is given by above-mentioned Γ distribution functions, scattering strength I is by from various radius R₁Particle (mean radiuss are R₀) superposition of scattering that produces is given, then exist particle diameter distribution it is irregular in the case of scattering strength I use above-mentioned formula (3) and (4) represented by following formula (5).

[number 6]

It is M with regard to the range parameter of the particle diameter distribution in formula (5), as analysis result, mark is used as by the conversion of formula (6) Standardization dispersion value σ (%) and export.

[number 7]

According to above-mentioned formula (5), in operation (B), by simulation, by value and the standardization point assumed of the radius R1 for assuming Scattering strength I that value calculates angle of scattering (2 θ) is dissipated, theoretical scattering profile is obtained.

Next, in operation (C), by method of least square carry out the theoretical scattering profile calculated by scattering strength I with Determine the curve matching of scattering profile.

In contour fitting, the variable for carrying out precise treatment is mean diameter (nm), standardization dispersion value (%).Additionally, profile Being fitted is carried out by way of method of least square becomes minimum with the residual sum of squares (RSS) Z value for determining profile and theory scattering profile, The residual sum of squares (RSS) Z value is more little, thinks that the precision of particle diameter parsing is higher.In general, two if Z values are decreased below 2% Profile substantially overlaps on visual derection level, can determine whether to restrain.It is preferred that Z values are less than 1%, again more preferably less than 0.5%.Make Average primary particle diameter and standardization dispersion value for variable during convergence is obtained as analysis result.

If determining the X-ray comprising extra small angle scattering region to scatter in operation (A), then, due to analytical range bag Include than larger particle diameter, a kind of particle diameter distribution assumed in operation (B) is a kind of average primary particle diameter and assumes standardization In the fitting parsing of operation C of dispersion value, residual sum of squares (RSS) Z value does not fully decline sometimes, determines profile with theoretical scattering profile Do not show good consistent.

Its reason is that particle diameter distribution is not a kind of, also includes that the pigment particles with bigger particle diameter, senior coagulation are formed Particle etc., it is assumed that with multiple particle diameter distributions, import new particle diameter distribution model.

In operation (D), until the residual sum of squares (RSS) Z value obtained by operation (C) be less than 2%, plus new radius R_n+1Value (n be integer, R_n＜ R_n+1) and the standardization dispersion value of respective hypothesis set multiple particle diameter distribution models, repeat n Secondary above-mentioned operation (B) to (C).

Specifically, if it is assumed that the new particle diameter distribution model with bigger mean diameter, its radius is set to into R₂ R is now set to (₂＞ R₁), scattering strength I of each composition is set to into I (1) and I (2), then the left item of early stage scattering strength formula (5) is such as Formula (7), (8) are corrected like that.

[number 8]

M₁It is the 1st kind of particle diameter distribution width parameter.

[number 9]

M₂It is the 2nd kind of particle diameter distribution width parameter.

Similarly, in the case where the 3rd radius R3, the distribution more than which is assumed, it is also possible to be described as I (3), I (4)··I(n)。

The total scattering intensity I of the particle diameter distribution model system with 2 mean diameters_TotalRepresented by formula (9).

I_Total=k (1) I (1)+k (2) I (2) (9)

K (1), k (2) are the scale factors of the ratio of components for representing each composition.

Similarly, it is assumed that the particle diameter distribution model with the mean diameters of more than 3, using total n particle diameter distribution mould Type, can describe total scattering intensity as formula (10).

I_Total=k (1) I (1)+k (2) I (2)++ k (n) I (n) (10)

In the multiple particle diameter distributions of early stage, volume fraction w (1) of such as n each particle diameter distribution composition, w (2) w (n) Ratio by shown in formula (11) is represented.

w(1)：w(2)：···：W (n)=k (1)：k(2)：···：k(n)···(11)

In contour fitting, the variable for carrying out precise treatment is the mean diameter (nm) of each particle diameter distribution composition, represents each particle diameter The standardization dispersion value (%) of the width of distribution, and each composition volume fraction (%).Additionally, contour fitting is using as measure wheel The wide Z values with the residual sum of squares (RSS) of complete theoretical scattering profile become minimum mode to be carried out, and determines above-mentioned each variable.

In the case that contour fitting in this (D) operation is not restrained well, i.e. do not obtain residual sum of squares (RSS) Z value most During little value, reason is that the variable that should be determined is excessive sometimes.Now, with the standardization dispersion value obtained in (C) operation as reference The standardization dispersion value of each particle diameter distribution composition is fixed.By this operation, carried out by the minimum method of least square of variable Contour fitting in convergence become easy.Thus, the mean diameter of each particle diameter distribution composition, standardization dispersion value (%), and each The volume fraction (%) of composition is obtained as analysis result.
