Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a red pigment composition that has high dispersibility and excellent brightness, a method for producing the same, and a color filter comprising the red pigment composition in a red pixel part.SOLUTION: The present invention provides a red pigment composition for color filters comprising a red organic pigment and an inorganic fine particle. When a particle size of the inorganic fine particle with a refractive index of 1.3-1.8 is D1, and a particle size of the red organic pigment is D2, D1/D2 is 0.15-0.99.SELECTED DRAWING: None 【課題】分散性が高く優れた輝度を有する赤色顔料組成物、およびその製造方法、該赤色顔料組成物を赤色画素部に含有するカラーフィルタを提供する。【解決手段】赤色有機顔料と無機微粒子からなるカラーフィルタ用赤色顔料組成物において、屈折率が１．３〜１．８である無機微粒子の粒子径をＤ１、赤色有機顔料の粒子径Ｄ２とすると、Ｄ１／Ｄ２が、０．１５〜０．９９の範囲にあること特徴とするカラーフィルタ用赤色顔料組成物。【選択図】なし
