Color material dispersion liquid, photosensitive color resin combination, colored filter, liquid crystal display Equipment and oganic light-emitting display device

Technical field

The present invention relates to colored filter color material dispersion liquid, colored filter photosensitive color resin combination, coloured silk Colo(u)r filter, liquid crystal display and oganic light-emitting display device.

Background technology

In recent years, with the development of the development of personal computer, especially portable personal computer, liquid crystal display Demand increases therewith.The popularity rate of Leading format device (mobile phone, smart mobile phone, tablet PC) is also being improved, liquid crystal display There is the situation expanded day by day in the market of device.In addition, nearest higher organic el display of visibility etc using self-luminous Oganic light-emitting display device, also serves as image display of future generation and attracts attention.In the performance of these image displays In, the reduction of the further higher image quality such as contrast, raising of color reprodubility or consumption electric power is expected strongly.

Existing display device is mostly on the basis of the sRGB (IEC61966-2-1) of the international standards of chrominance space. However, in order to seek the requirement for showing, further improving color reprodubility closer to material object, extremely having for correspondence than sRGB The requirement of the AdobeRGB of wider array of colour gamut display device is improved.AdobeRGB specifications are advocated by Adobe Systems Chrominance space definition, the three primary colors in AdobeRGB determine by the chromaticity coordinate x and y in XYZ color specification systems as described below. AdobeRGB specifications are characterised by thering is wider colour gamut on green direction compared with sRGB specifications.

It is red：X=0.64；Y=0.34

It is green：X=0.21；Y=0.71

It is blue：X=0.15；Y=0.06

In addition, having the DCI (Digital of wider colour gamut on red and green direction compared with sRGB for meeting Cinema Initiatives) display device of specification also has required.

Colored filter is used in these liquid crystal displays, oganic light-emitting display device.Such as liquid crystal display Coloured image formation, be the face for each pixel for being directly colored as constituting colored filter by the light by colored filter Color, synthesizes the light of these colors and forms coloured image.As light source now, in addition to existing cold cathode ray tube, Have and utilize white luminous organic luminescent assembly, the situation of white luminous inorganic light-emitting component.In addition, organic light emitting display is set It is to use colored filter for color adaptation etc. in standby.

In this case, expect for high brightness, high-contrast, raising of color reprodubility etc. in colored filter Also in improving.

Here, colored filter typically has transparency carrier, is formed on transparency carrier and comprising Red Green Blue Colored pattern dyed layer, be formed at the light shielding part on transparency carrier to divide each colored pattern.

As the forming method of pixel in colored filter, wherein, by dichroism, durability, pattern form and precision Set out etc. viewpoint, the most widely used pigment dispersion method with average excellent specific property.

In the colored filter with the pixel formed using pigment dispersion method, in order to realize that high brightness, height are right Than degree change, and study the granular of pigment.Think to utilize by pigment granular, can lower and penetrate colour caused by pigment particles The scattering of the light of optical filter, realizes high brightness, high-contrast.

However, the pigment particles through granular easily condense, therefore there is asking for dispersed or dispersion stabilization reduction Topic.

It is used as the method for the dispersion method for improving the pigment through granular, it is known that effectively using dispersant.Such as patent The purpose of document 1 is to provide a kind of excellent colorimetric properties, developability and the good colored filter coloring of storage stability Composition, its disclosure has used block copolymer as the colored filter coloured composition of pigment dispersing agent, and the block is total to Polymers has：The A blocks of specific recurring unit containing tool amino or ammonium salt base, containing with the alcohol part from carboxylate Alkylene oxide group chain specific recurring unit, with acidic groups recurring unit B block.

In addition, to be to provide a kind of excellent colorimetric properties, developability and storage stability good for the purpose of patent document 2 Colored filter coloured composition, its disclosure has used copolymer as the colored filter coloring compositions of pigment dispersing agent Thing, the copolymer contains：Specific recurring unit with amino or ammonium salt base, the recurring unit containing carboxylate and with acid The recurring unit of property base, and the recurring unit containing carboxylate is set to special ratios, by weight average molecular weight and number-average molecular weight Than being set to special ratios.

On the other hand, in colored filter, 3 points of region of connection red, green, blue color pixel turns into reproducible color Boundary.That is, the bigger colored filter of triangle obtained by 3 points of red, green, blue color pixel, display device can be again on picture The scope of existing color is wider.

In order to realize that above-mentioned AdobeRGB or DCI etc. has the chrominance space of wider colour gamut, especially require colour filter The green pixel of mating plate is set to greenness { (x=0.14~0.30, y=0.55~0.75), the more preferably (x=of high color density 0.14~0.30, y=0.57~0.75), even more preferably from (x=0.14~0.30, y=0.61~0.75) region.

In the past, as the widely used viridine green of green pixel institute, such as C.I. naphthol greens can be enumerated (C.I.Pigment Green) 7 (hereinafter sometimes referred to simply as PG7), C.I. pigment green 36s (hereinafter sometimes referred to simply as PG36), C.I. Naphthol green 58 (hereinafter sometimes referred to simply as PG58).

However, when to make green pixel in the way of the greenness region for realizing above-mentioned high color density, existing using PG7 The problem of luminance-reduction of the green pixel.When forming green pixel using PG7 as main green color material, as dark Colored filter.

In addition, using PG36 when to make green pixel in the way of the greenness region for realizing above-mentioned high color density, though Unlike PG7 is so serious, but the problem of there is the luminance-reduction of the green pixel.

If in addition, using PG58, although brightness is uprised, making the greenness region comprising above-mentioned high color density It is not only problematic in volume production during green pixel, it is necessary to make green pixel very thick-film, and because only green pixel is by thick film Change, therefore be difficult to maintain colorized optical filtering piece performance.Furthermore, even if being used only in PG58, the greenness region of above-mentioned high color density still In the presence of the region that can not be realized, there is boundary in terms of green pixel is made in the way of as bigger triangle.

Patent document 3 is described as realizing the green target colorimetric of high color density without carrying out thick-film, and The colored filter colored resin composition of the green pixel of high brightness can be formed, the face containing high chlorination ZnPc has been used Material.However, also requiring higher brightness.

On the other hand, patent document 4 is used and concerned bromination ZnPc as green pixel formation in recent years using providing It is open for the purpose of the colored filter colored curable resin composition that foreign matter failure is suppressed caused by pigment A kind of colored filter coloured composition, it is simultaneously used as the amine system polymer that pigment dispersing agent contains specific Component units Pigment dispersing agent, has the Component units of 4 grades of ammonium salt bases and without 4 grades of ammonium salt bases with containing as aggregation inhibitor on side chain Component units block copolymer aggregation inhibitor.However, the zinc bromide phthalocyanine color that patent document 4 is recorded substantially is C.I. naphthol green 58 (PG58), it is impossible to obtain that the blue green and high viridine green dispersion liquid of brightness of band is presented.

In addition, green pixel, which exists, easily occurs the problem of display is bad.More specifically, the liquid crystal of lateral electric field type Show that equipment has the dyed layer of colored filter in liquid crystal drive electric field, therefore significantly influenceed by the electrical characteristics of dyed layer. In the case where green pixel has used PG36, in the liquid crystal display of lateral electric field type, the electricity for occurring green pixel is special Property caused by the various displays such as liquid crystal aligning is chaotic, switching threshold deviation is caused sintering phenomenon it is bad.Such display is not It is good when green pixel has used PG58, more significantly occur and throw into question.

In patent document 5, in the liquid crystal display of lateral electric field type, as colored filter dyed layer it is electrical Matter will not have undesirable effect to the performance of handoffs of liquid crystal, even if the protective layer for being not provided with transparent resin also ensures that sufficient property Can, and as the colored filter of high color reprodubility can be tackled, disclose to form the dyed layer of green pixel and contain specified quantitative Following PG36, and with specific dielectric loss angle tangent (tan δ) value.

However, for technology disclosed in patent document 5, even if reducing, display is bad, and brightness is also not enough, and extensive Color reprodubility this respect it is also not enough.

On the other hand, in patent document 6, as brightness-adjusting without making colored filter that high-contrast is reduced with green Colour cell compound, is disclosed containing PG58 and yellow organic pigment, and containing selected from blue pigment, red pigment, violet pigment and Any green composite of orange pigment.

However, for technology disclosed in patent document 6, in extensive color reprodubility this respect and insufficient.

I-1. the color material dispersion liquid of the first aspect of the present invention

The colored filter of the first aspect of the present invention color material dispersion liquid, is containing coloured material, dispersant, the color with solvent Material dispersion liquid；It is characterized in that：

The acid number of the dispersant is 1~18mgKOH/g, and the glass transition temperature of the dispersant is more than 30 DEG C.

[chemical formula 3]

The color material dispersion liquid of the present invention has above-mentioned specific acid number with particular glass transition temperature, containing upper due to using The block copolymer (P1) and the block copolymer and the salt form of above-mentioned specific compound forming salt for stating specific Component units are embedding It is at least one kind of as dispersant in section copolymer (P2), therefore can make that color material dispersion stabilization is excellent, suppressing development residue hair Development adaptation and solvent redissolution property excellent photosensitive color resin combination while raw.In addition, using the color material point The colored filter that dispersion liquid is modulated photosensitive color resin combination, can the excellent dyed layer of degree of being contrasted.

By using with above-mentioned specific acid number and particular glass transition temperature, containing above-mentioned specific Component units In block copolymer (P1) and the block copolymer and the salt form block copolymer (P2) of above-mentioned specific compound forming salt It is at least one kind of as dispersant, though so that the effect for playing the effect above is not illustrated, can be presumed as follows.

Pigment dispersing agent is known as in the past, by embedding with the A comprising tool amino or the specific recurring unit of ammonium salt base Section, the block copolymer with the B block of the recurring unit containing tool acidic groups, can improve dispersiveness, dispersion stabilization, alkali development Property (such as patent document 1,2 and 4).

However, being studied through the present inventor etc., as a result for the method that patent document 1 is recorded, particularly its development is closely sealed Property and not up to realistic scale.For the method that patent document 1 is recorded, as be described hereinafter shown in comparative example, thus it is speculated that reason is embedding The specific recurring unit that the part for deriving from alcohol containing carboxylate in section copolymer includes alkylidene epoxide chain, therefore glass transition Temperature step-down.If be the temperature lower than developer temperatur as the glass transition temperature of the block copolymer of pigment dispersing agent, Or close temperature, then the molecular motion of dispersant becomes big when developing, as a result, speculating development adaptation reduction.

In addition, in the method that patent document 2 and 4 is recorded, especially its adaptation of developing also does not reach realistic scale.Patent text In the method for offering 2 and 4 records, as be described hereinafter shown in comparative example, thus it is speculated that its reason is the acid number of dispersant than defined herein Value it is high, although therefore developability is excellent, polarity is too high easily peeling-off on the contrary.In the method that patent document 2 and 4 is recorded, Speculate due in the absence of making dispersant while meeting the conception of specific low acid number and specific high glass-transition temperature, thus it is aobvious Shadow adaptation does not reach realistic scale.

As a result the present inventor etc. has found through concentrating on studies, if the acid of specific block copolymer or salt form block copolymer Value is higher, then adaptation of developing is unable to reach realistic scale, and solvent redissolution property deteriorates；If but below particular value Low acid number, then the inhibition with development residue, and can obtain being difficult to peeling-off excellent developing adaptation, and it is molten Agent redissolution property is excellent.On the other hand, even if finding that the specific block copolymer or salt form block copolymer are above-mentioned specific The following low acid number of value, if but glass transition temperature is lower than setting, and development adaptation is not up to realistic scale；If using The block copolymer or salt form block copolymer of more than 30 DEG C higher than developer temperatur of glass transition temperature, then adaptation of developing It is excellent.If speculating the block copolymer using more than 30 DEG C higher than developer temperatur of glass transition temperature or salt form block copolymerization Thing, then due to suppressing the molecular motion of dispersant during development, therefore suppress the reduction of development adaptation.

The color material dispersion liquid of the present invention at least contains coloured material, dispersant and solvent, is not damaging the scope of effect of the present invention It is interior, it can further contain other compositions.

Below for each composition of such color material dispersion liquid of the invention, by having the dispersant of characteristic in the present invention Start to illustrate successively.

In the present invention, as dispersant, using in above-mentioned block copolymer (P1) and above-mentioned salt form block copolymer (P2) It is at least one kind of, wherein, the acid number of the dispersant is 1~18mgKOH/g, the glass transition temperature of the dispersant for 30 DEG C with On.
