Problems solved by technology

[0004] However, in the case of increasing the acid value of the above-mentioned colored photosensitive resin composition to lead to a fast development speed in order to improve productivity, there is a problem that the adhesiveness is lowered and pattern errors are likely to occur during development. The surface roughness of the coating film formed by the resin composition becomes larger
In particular, the colored layer formed on the bottom using the colored photosensitive resin composition has a serious problem of not being able to maintain the pattern with a small amount of exposure due to the high concentration of the pigment
[0005] Korean Laid-Open Patent No. 2009-0034774 relates to a photosensitive resin composition for a black resist containing a multifunctional thiol compound, a black matrix for a color filter and a color filter using the same, and discloses a photosensitive resin composition for a black resist. The contents of the photosensitive resin composition for black resists, the photosensitive resin composition for black resist contains (A) alkali-soluble resin, (B) photopolymerizable monomer having one or more ethylenically unsaturated bonds, (C) photopolymerizable monomer A polymerization initiator, (D) a polyfunctional thiol compound represented by the general formula (I), and (E) one or more coloring materials selected from black organic pigments, mixed-color organic pigments, and light-shielding materials are essential components, but there is no Discloses countermeasures against the above problems, most importantly there is a problem that it cannot be applied to the pattern layer of the color filter
