Zusammenfassung:PROBLEM TO BE SOLVED: To provide a colorant dispersion liquid for providing a black matrix capable of forming a high-definition pattern having high resistance and high light-shielding properties when a black pigment is used as a colorant.SOLUTION: There is provided a polymerizable compound (A) having a bisphenol skeleton, a colorant (B), an extender pigment (C), a dispersant (D) and a solvent (E). The polymerizable compound (A) preferably is an ethylenically unsaturated compound which is a reaction product obtained by esterification reaction between a polybasic acid anhydride and an epoxy addition compound having a structure in which an unsaturated monobasic acid is added to an epoxy compound represented by the following general formula (I).SELECTED DRAWING: Figure 1 【課題】着色剤として黒色顔料を使用する場合に、高抵抗であり、遮光性が高く、高精細なパターンの形成が可能なブラックマトリックスを与える着色剤分散液を提供すること。【解決手段】ビスフェノール骨格を有する重合性化合物(A)、着色剤(B)、体質顔料(C)、分散剤(D)及び溶剤(E)を含有する着色剤分散液。重合性化合物(A)は、下記一般式(I)で表されるエポキシ化合物に、不飽和一塩基酸を付加させた構造を有するエポキシ付加化合物と、多塩基酸無水物とのエステル化反応により得られる反応生成物であるエチレン性不飽和化合物であることが好ましい。【選択図】図1
