금속 화합물을 함유하고 있더라도 명도 저하의 정도가 작은 컬러 필터를 형성할 수 있는 착색 경화성 수지 조성물, 해당 착색 경화성 수지 조성물로부터 형성되는 컬러 필터, 및 해당 컬러 필터를 포함하는 표시 장치를 제공하는 것을 과제로 한다. 히드록시기를 가지는 탄소수 1~40인 지방족 카르복실산의 음이온을 가지는 금속염(A), 프탈로시아닌계 착색제와 황색 착색제를 포함하는 착색제(B), 수지(C), 중합성 화합물(D) 및 중합 개시제(E)를 포함하는 착색 경화성 수지 조성물에 의하면, 금속 화합물을 함유하고 있더라도 명도 저하의 정도가 작은 컬러 필터, 및 그것을 포함하는 표시 장치를 제공할 수 있다. The present invention addresses the problem of providing: a coloring curable resin composition which is capable of forming a color filter that is suppressed in decrease of the brightness even if a metal compound is contained therein; a color filter which is formed from this coloring curable resin composition; and a display device which comprises this color filter. A coloring curable resin composition according to the present invention contains (A) a metal salt which has an anion of an aliphatic carboxylic acid that has a hydroxy group and 1-40 carbon atoms, (B) a coloring agent which contains a phthalocyanine-based coloring agent and a yellow coloring agent, (C) a resin, (D) a polymerizable compound and (E) a polymerization initiator. This coloring curable resin composition enables the achievement of a color filter which is suppressed in decrease of the brightness even if a metal compound is contained therein, and a display device which comprises this color filter.
