Problems solved by technology

[0005] However, in order to make the spacer light-shielding, it is generally considered to add a colorant containing a pigment to the photosensitive composition, but with the addition of the colorant, the curability of the spacer layer decreases due to the decrease of the transparent component. Small, and the characteristics may be damaged by the influence of impurities derived from pigments, etc.

[0387] [Manufacturing method of colored photosensitive composition]

[0388] The colored photosensitive composition of the present invention is prepared according to a conventional method. Hereinafter, although an example is given and it demonstrates concretely, the manufacturing method of the coloring photosensitive composition in this invention is not limited to this method.

[0389] From the viewpoint of ensuring the dispersion stability of the pigment, the coloring photosensitive composition of the present invention is preferably prepared in the following manner to prepare a pigment dispersion liquid in advance and to mix other components therein.

[0390] [1] Manufacturing method of pigment dispersion liquid

[0391] Predetermined amounts of the pigment, solvent, and dispersant, and, if necessary, a dispersion aid are weighed, and in the dispersion treatment step, the pigment is dispersed to obtain a liquid pigment dispersion. In this dispersion treatment step, a paint ...

Abstract

A colored photosensitive composition containing a pigment, a binder resin, a photopolymerizable monomer, and a photopolymerization initiator, wherein the pigment contains a pigment represented by the following (A) and a pigment represented by (B) pigment. (A) One selected from C.I. Pigment Orange 43, C.I. Pigment Orange 64 and C.I. Pigment Orange 72; (B) C.I. Pigment Blue 60.

Description

technical field [0001] The present invention relates to a colored photosensitive composition and the like. Specifically, it relates to a colored photosensitive composition preferably used for forming a black photo-spacer in a color filter such as a liquid crystal display, and a black photo-spacer and a black photo-spacer formed using the colored photosensitive composition. Color filter containing this black photo-spacer. Background technique [0002] A liquid crystal display (LCD) utilizes the property of switching an alignment method of liquid crystal molecules by on / off of a voltage applied to the liquid crystal. On the other hand, each member constituting a cell of an LCD is often formed using a photosensitive composition typified by photolithography. The application range of the photosensitive composition also tends to be further expanded in the future because it is easy to form a fine structure and easy to handle a substrate for a large screen. [0003] However, in a...
