To provide a colored resin composition capable of realizing a wide color gamut, having high contrast, and excellent in patterning property.SOLUTION: A colored resin composition contains a colorant (A), a solvent (B), an alkali-soluble resin (C), a photopolymerization initiator (D), and a photopolymerizable monomer (E). The colorant (A) has a red colorant (a-1) having at least one absorption peak with an absorbance of 1.0 or more at a wavelength of 560 nm or more when measured at a concentration of 10 ppm and a measurement cell length of 1 cm, using water or propylene glycol monomethyl ether acetate as a solvent. The content of the colorant (A) is 30 mass% or more based on the total solid content of the colored resin composition.SELECTED DRAWING: None 【課題】 広色域の実現が可能であり、コントラストが高く、パターニング性に優れる着色樹脂組成物を提供する。【解決手段】 （Ａ）着色剤、（Ｂ）溶剤、（Ｃ）アルカリ可溶性樹脂、（Ｄ）光重合開始剤、及び（Ｅ）光重合性モノマーを含有する着色樹脂組成物であって、前記（Ａ）着色剤が、溶媒として水またはプロピレングリコールモノメチルエーテルアセテートを用い、濃度１０ｐｐｍかつ測定セル長が１ｃｍで測定したときに、吸光度１．０以上の吸収ピークが波長５６０ｎｍ以上に少なくとも１つ以上存在する赤色着色剤（ａ－１）を含み、前記（Ａ）着色剤の含有割合が着色樹脂組成物の全固形分に対して３０質量％以上であることを特徴とする着色樹脂組成物。【選択図】なし
