Zusammenfassung:An object of the present invention is to provide a colored cured film having both excellent adhesiveness and solvent resistance, a coloring composition which provides the colored cured film, and a display device having the coloring composition. The coloring composition includes (A) a coloring agent, (B) a binder resin, (C) a radical polymerizable compound, (D) a photo-radical generating agent, and (E) a compound having a structure in which a group represented by Chemical formula (E0) is directly bound to an aromatic ring. In Chemical formula (E0), R^I is a hydrogen atom or an alkyl group having 1-4 carbon atoms; R^II is a hydrogen atom or an alkyl group having 1-4 carbon atoms; x is 1 or 2; and ′*′ is a binding bond which is directly bound to an aromatic cycle. 본 발명의 과제는 밀착성 및 내용제성의 양쪽이 우수한 착색 경화막, 상기 경화막을 부여하는 착색 조성물 및 상기 경화막을 구비하는 표시 소자를 제공하는 것이다. 본 발명의 해결수단은, (A) 착색제, (B) 결합제 수지, (C) 라디칼 중합성 화합물, (D) 광 라디칼 발생제, 및 (E) 하기 화학식 (E0)으로 표현되는 기가 방향환에 직결된 구조를 갖는 화합물을 함유하는 것을 특징으로 하는 착색 조성물이다.(화학식 (E0) 중, R은 수소 원자 또는 탄소수 1 내지 4의 알킬기이고, R는 수소 원자 또는 탄소수 1 내지 4의 알킬기이며, x는 1 또는 2이고, 「*」는 방향환에 직접 결합하는 결합손을 나타냄)
