Description of the Invention: [Technical Field] The present invention relates to a pigment dispersion liquid, a color filter using the pigment dispersion liquid, a negative flow resistance group, and a (four) negative material (four) silk color A sheet, and a color filter dicing display device and an organic light emitting display device. [Prior Art] In recent years, with the development of personal computers, especially the development of portable personal computers, the demand for liquid crystal displays has increased. Moreover, the popularity of LCD TVs for home use has also increased recently, and the market for liquid crystal displays has expanded. Further, in the performance of the liquid crystal display, (4) it is desired to further improve the contrast and color reproducibility, and further reduce the image quality and power consumption. In such a situation, the expectation of high brightness and high contrast in the color filter having the color display function of the liquid crystal display is improved, and the color reproducibility is also increased. In particular, recently, for television use, (4) the power consumption of the backlight is reduced, and (4) the backlight is recorded, and the high luminance (4) becomes high. Further, the above-mentioned problems are also the same in the organic EL display which is expected to be popular in the future. The problem of high luminance and improved color reproducibility is solved in the display. Here, as a method of producing a general color light-sensitive sheet, a photocurable negative-type photoresist composition and a coating film formed by dispersing pigments of respective colors can be used on a substrate on which a patterned light-shielding portion is formed. A method of forming a colored layer of each color into a pattern by interposing a desired pattern shape 100107105 4 201139476. The color filter is formed by forming three colors of red, green, and blue on a transparent substrate such as glass. On the red and green colored patterns, only red or green pigments are difficult to obtain the desired spectroscopic spectrum, so the mixed yellow pigment adjusts the spectrogram* spectrum. In general, s is a color filter in which a pigment is dispersed, which is caused by scattering of light due to a pigment, and has a problem that the degree of polarization of liquid crystal control is disturbed. That is, it is necessary to block light (OFF state) light, electric leakage, and when light must be transmitted (on state), the transmitted light is weakened, so there is a redundancy ratio (contrast) on the display device in the ON state and the OFF state. Low problem. Therefore, conventionally, C.I. Pigment Yellow 150 which is suitable for improving the contrast ratio has been used as a yellow pigment for adjusting the above red and green colors. However, when C.I. Pigment Yellow 150 is used, there is a problem that the brightness cannot be sufficiently improved. In contrast to the dye, the use of a pigment can solve the problem of low penetration rate. Therefore, Patent Document 1 discloses a green resin composition using CI. Pigment Yellow 138. However, in the past, when C I Pigment Yellow 138 was used as the pigment, the contrast was lowered, and in particular, it was difficult to use it in television use. • For the purpose of green pigment preparation with intercalation, color strength, and high transparency, Patent Document 2 describes green of monosulfonic acid and copper phthalocyanine containing cI pigment green 36 and CI pigment 138. Pigment formulation. However, in the case of using a conventional pigment dispersant as disclosed in Patent Document 2, there is a problem that 100107105 201139476 cannot sufficiently improve brightness and contrast. On the other hand, in Patent Document 3, 'the green pigment dispersion for forming a coating film having excellent brightness can be obtained as a long-term dispersion stability, and contains a silver pigment corresponding to CI Pigment Green 58. The green pigment is a main pigment and contains a sulfonated pigment derivative as a pigment dispersion of the sub-pigment ''' ^ 1. However, as shown in the comparative example described later, a method as shown in Patent Document 3 is used. In the case of the dye-type pigment dispersant, there is a problem that the CI pigment green 58 is sufficiently miniaturized and the contrast cannot be sufficiently improved. [Prior Art Document] Unexamined [Patent Document] Patent Document 1: Japanese Patent Laid-Open No. 11-256053 Patent Document 2: Japanese Patent Laid-Open Publication No. 2008-538792 (Patent Document 3): Japanese Patent Application Publication No. 2009-126994 (Summary of the Invention) The present inventors In the review that meets the requirements for high brightness and high brightness of color filters, the face obtained by the dispersing machine for research is not the one that can be obtained in the dispersing machine for the production of the helium ring type. I, such as As shown in the examples, CI pigment green 58 has a higher dispersibility in the initial stage of dispersion, and in the dispersion machine for production, it is less at the time when it becomes the highest. If the dispersed phase is lengthened, The score is deteriorated, and as a result, the contrast is significantly reduced. If it is slightly over 100107105 6 201139476, the knife edge is weakened and the process margin is small. 'The process characteristics are only slightly changed for any reason'. The possibility of mass production of defective products. The present invention is completed as described above in order to provide a color filter for achieving high brightness and contrasting, and having a large processing margin by the production dispersion machine. a pigment dispersion liquid; and a color light-passing sheet which is excellent in pigment dispersibility, high-brightness, and contrasting in the south, and has a color-developing light-emitting sheet which is excellent in imageability - a negative-type photoresist sheet; a negative-light-resisting composition for a color furnace sheet excellent in stability, a color formed using the negative-type photoresist composition, a light-receiving sheet, a liquid crystal display device having the color filter, and an organic light-emitting display Loading For the purpose of the present invention. (Means for Solving the Problem) The inventors of the present invention have repeatedly made efforts to achieve the above-mentioned purpose, and the present invention has been combined with the use of an amine group of the constituent unit of the polymer. The specific block copolymer of the salt, and the CJ.1; hopper\38 stone ritual organism as a pigment dispersion enthalpy, can obtain the requirements of far-reaching high-level contrast, and by the production of the dispersing machine The team's cockroaches, the pigment dispersion for the light film; and the color filter that can form the pigment dispersion and the same-degree and contrast, and the image quality is excellent - the negative color film Photoresist composition - The present invention has been completed in accordance with such findings.

It is not particularly limited, and it varies depending on the kind of the pigment to be used, and is preferably in the range of 1 Å to 1 〇〇 nm and more preferably in the range of 10 to 50 nm. By setting the average primary particle diameter of the pigment to the above range, the liquid crystal display device and the organic light-emitting display device produced by using the negative-type photoresist composition for a color filter of the present invention can be made highly contrasted and of high quality. . Further, according to the conventional pigment dispersant, as the particle size of the pigment is reduced, the amount of the pigment dispersant must be large, and there is a problem that the alkali developability is lowered and the residue is increased.
