Description
Technical field
The present invention relates to the black matix pigment dispensing composition of the formation of the black matix for liquid crystal display and contain
The black matix of the black matix pigment dispensing composition disperses anti-corrosion agent composition with pigment.
Background technique
Make mostly in the image-displaying member of computer, colour television set, mobile phone, tablet device, game terminal machine etc.
Use crystal liquid mode.Liquid crystal image display element using formed the colored filter of each color pixel and the liquid crystal with fast gate action come
Image is shown on picture.
Secondly, colored filter is formed usually on the surface of the transparent substrates such as glass, plastic plate has striated or mosaic
The black matix (black matrix) of the opening portion of shape etc., then, on opening portion sequentially forms 3 kinds of red, green, blue etc. or more no
With the pixel of pigment.
Here, black matix inhibit assorted between colour mixture and prevent exposure to play the function of improving contrast.Therefore,
High light-proofness is needed, the evaporation film of high chromium for film light-proofness etc. is had used.However, the process for formation is multiple
The high such reason of miscellaneous and price utilizes the photoetching process (pigment method) containing pigment and photoresist recently.
For the pigment method, as black pigment, using carbon black etc. black pigment or several pigment be applied in combination make into
For black.
In turn, high light-proofness in order to obtain, it is also desirable to the contents of a large amount of cooperation pigment itself, but pigment concentration is higher, developability,
Other required performances such as resolution ratio, adherence, stability are lower, and there are limits on improving light-proofness.On the other hand, right
Seek filming in the film for forming colored filter, becomes and have to the high concentration of pigment come the case where reply.
But, recently in color liquid crystal display arrangement, display distinctness is directly related to the increase of device itself sale, and
The demand that distinctiveness improves is very strong.Therefore, eliminating, which becomes color, the colored filter, black of the reason of damaging distinctiveness such as spreads and sinks in out
The pattern of color base matter forms bad for very big project.
When forming black matix by photoetching process, firstly, black matix is coated on substrate with anti-corrosion agent composition.Thereafter,
It is exposed across the exposure mask with expected pattern and with ultraviolet light, makes the curing of coating of exposure portion.Also, by unexposed portion
Film removed with developer solution, thus formed as above-mentioned desired pattern black matix.At this point, good figure in order to obtain
Case needs anti-corrosion agent composition to have good pattern reproduction.Such as, it is desirable that do not develop in unexposed portion at the end of development
Residue, exposure portion have sufficient line reproducibility, can form the pattern etc. of sharp edge.
However, light-proofness height refers to that the light-proofness relative to ultraviolet light is also high as black matix.Therefore, in exposure portion
In point, even if film coated surface solidifies, ultraviolet light can not be by with uncured state residual near substrate.And
And generate following phenomenons: developed liquid is invaded and is tailed off at leisure for uncured and remaining part, final exposed portion whole quilt
It removes and black matix disappearance.
In this way, tailing off after being completely removed from portion unexposed first to exposure portion and being unable to get the rule as black matix
The time span of qualitative energy is referred to as development latitude (Development Latitude).The development latitude is due to not exposing less
Tailing off, disappearing for exposure portion immediately occurred in light part after being removed, so the opportunity that confirmation terminates development has difficulties.Especially
It is, for above-mentioned such anti-corrosion agent composition through high pigment levels, due to the uncured degree in exposure portion
It is easy to increase, so being unable to fully obtain development latitude, adherence is also reduced.Therefore, unexposed portion can not completely remove, or
Person's exposure portion tails off and performance as defined in being unable to get etc., becomes very big problem in terms of process management.
Therefore, it as the composition of black matix, from the perspective of never making the development in developing procedure that difficulty occur, also seeks
Seek the composition that can be realized enough high shading rates (OD value), antiradar reflectivity.Moreover, mobile phone etc. use on the way, from preventing
Also seek antiradar reflectivity on picture from the perspective of dazzle.

<preparation of the black matix pigment dispensing composition of Examples 1 to 8 number>
In order to become the combination (usage amount of each material in table 1 is quality %) of table 1, a variety of materials are mixed and use ball mill
It is kneaded, thus the black matix pigment dispensing composition of preparation 1~8.
<Examples 1 to 5, comparative example 1~3 black matix with pigment disperse anti-corrosion agent composition preparation>
Using high-speed mixer, 1~No. 8 each black matix is uniformly mixed with pigment dispensing composition and other materials
After the composition (usage amount of each material in table 2 is quality %) of table 2, it is filtered with 0.5 μm of the filter in aperture, thus
Obtain each black matix pigment dispersion anti-corrosion agent composition of Examples 1 to 5, comparative example 1~3.
<evaluation test>
(initial viscosity, 40 DEG C save 7 days after viscosity)

Relative to the sample for determining above-mentioned OD value, by respectively reflection of the portion at each wavelength of 460nm, 560nm and 660nm on the spot
Rate is measured with reflectance meter (great Zhong electronics corporation system, photal MC-7300:SC).
Table 1
Table 2
Black matix pigment dispensing composition according to the present invention, by further cooperating the light for obtaining resist
Polymerizable compound, Photoepolymerizationinitiater initiater, alkali soluble resin can obtain viscosity change caused by there is no saving, dispersion surely
Qualitative excellent required black matix disperses anti-corrosion agent composition with pigment.
In turn, black matix according to the present invention disperses anti-corrosion agent composition with pigment, and high OD value and antiradar reflectivity can be obtained simultaneously
The film deposited.
In addition, according to mismatching barium sulfate or even if cooperating only a little remaining comparative example 1 and 2, it is enough being unable to get reflectivity
Low film.In turn, according to the comparative example 3 more than the use level for making barium sulfate, also still it is unable to get the sufficiently low film of reflectivity.
