Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter and a method of manufacturing the same, and is a color filter excellent in comparison and a method of manufacturing the same.

[Prior Art J color filter contains a dispersion composition for dispersing an organic pigment or an inorganic pigment, a polyfunctional monomer, a photopolymerization initiator, an alkali-soluble resin, and other components as a coloring photosensitive composition, and can be used They can be manufactured by forming a colored pattern by a %® photolithography method or the like. - In recent years, color filters have not only been used as a screen for liquid crystal display devices, but also have a tendency to expand in the use of television (television: TV). The tendency is to require a high degree of color characteristics in chromaticity, contrast, and the like. In particular, the contrast system is particularly noticed because it imparts a significant influence on the image quality in the display device.相对 In response to the above-mentioned requirements, it is required to disperse the pigment in a finer state (good dispersibility) and to disperse it in a stable state (good dispersion stability). In the case where the dispersibility is insufficient, the formed colored photoresist film is formed with irregular fringe (fringe: indentations at edge portions) or surface irregularities, which causes the color filter to be produced. The chromaticity or dimensional accuracy of the sheet is degraded' and there is a problem that the contrast is significantly deteriorated. The reason for the contrast reduction is, for example, the light leakage of 200928458 when the polarizing plates are cross-arranged due to scattering due to the back light of the pigment particles in the composition. For this reason, it is preferable that the average particle diameter in the colored composition is smaller because the high contrast of the color filter is taken into consideration. The technique of selecting pigment particles to enhance contrast has revealed a method of using a pigment having an average particle diameter of 100 to 300 nm (for example, refer to JP-A-2003-248115), or measuring an average particle diameter using an ultrasonic attenuation type particle size distribution analyzer. Select the particles in the specified range. Specifically, D84 is '1.0//m or less, D50 is 〇·5/ζ m or less, Di6 is 〇_3/zm or less, and the maximum peak is 〇. 5 /2 m or less. A method of pigment particles (for example, see Japanese Patent Laid-Open No. 2005-165307). However, since the surface area of the pigment particles becomes large when the particle diameter of the pigment is refined, the cohesive force between the pigment particles is enhanced, and it is often difficult to have a high degree, and the level is both dispersible and dispersion stable, even according to the aforementioned technique. The current situation is that the high contrast enthalpy of practical level has not been achieved, and further high contrast is desirable. Disclosure of the Invention Problems to be Solved by the Invention The present invention has been achieved in view of the above problems of the prior art. That is, the present invention provides a color filter capable of obtaining high contrast, and a method of producing such a color filter.

The occupancy rate of the secondary particles is 40% or less. The occupancy of the secondary particles needs to be 40% or less, preferably 25% or less, more preferably 10% or less. Here, the primary particle diameter of the pigment can be measured by an electron microscope (S-4800 manufactured by Hitachi High-Technologies Corporation) at a magnification of 100,000 times and n = 100 or more. The average particle diameter of the pigment can be measured by using a dynamic light scattering type particle size distribution measuring apparatus (Microtrack UPA-1 50 manufactured by Nikkiso Co., Ltd.), and can be measured by diluting with a dispersing medium of 200928458 as needed.

The pigment dispersion composition of the present invention is composed of a pigment -23-200928458 and a specific pigment dispersant, and may be formed using other components such as a resin component as needed. Since the pigment dispersion composition contains a specific pigment dispersant, the dispersion state of the pigment in the organic solvent is good, and good color characteristics are obtained, and high contrast can be obtained, for example, when constituting a color filter. In particular, it can exert excellent dispersion effects of organic pigments.
