Zusammenfassung:	To provide a photosensitive composition having good storage stability as a coloring composition and a photosensitive coloring composition, and capable of eliminating display failure of a liquid crystal display device caused by copper phthalocyanine, and a color filter and a liquid crystal display device formed by using the above composition.SOLUTION: A coloring composition comprises a halogenated metal phthalocyanine pigment (A), a dispersant (B), and a binder resin (C). The halogenated metal phthalocyanine pigment (A) comprises a halogenated copper phthalocyanine pigment (A1) and a halogenated aluminum phthalocyanine pigment (A2), in which the content of the halogenated aluminum phthalocyanine pigment (A2) is 3 to 11 pts.mass with respect to 100 pts.mass of the halogenated copper phthalocyanine pigment (A1). The dispersant (B) comprises a phosphoric acid-based resin type dispersant (B1) and/or a carboxylic acid-based dispersant (B2).SELECTED DRAWING: Figure 1 【課題】本発明は、着色組成物および感光性着色組成物として保存安定性が良く、かつ、銅フタロシアニンに起因する液晶表示装置の表示不良を解消できるの感光性組成物、及びそれを用いて形成されたカラーフィルタおよび液晶表示装置を提供することを目的とする。【解決手段】上記課題は、ハロゲン化金属フタロシアニン顔料（Ａ）、分散剤（Ｂ）、バインダ樹脂（Ｃ）を含む着色組成物であって、該ハロゲン化金属フタロシアニン顔料（Ａ）が、ハロゲン化銅フタロシアニン顔料（Ａ１）およびハロゲン化アルミニウムフタロシアニン顔料（Ａ２）を含み、ハロゲン化銅フタロシアニン顔料（Ａ１）１００質量部に対するハロゲン化アルミニウムフタロシアニン顔料（Ａ２）の含有量が３〜１１質量部であり、かつ、該分散剤（Ｂ）が、リン酸系樹脂型分散剤（Ｂ１）および／またはカルボン酸系分散剤（Ｂ２）を含むことを特徴とする着色組成物によって、解決される。【選択図】図１
