Zusammenfassung:	To provide a color filter and a color liquid crystal display device that are excellent in adhesion of a colored pattern and a residual film rate and also achieves a good cross-sectional shape and linearity.SOLUTION: A photosensitive coloring composition has a red pigment (A), a binder resin (B), a photopolymerizable compound (C), a photopolymerizable initiator (D), and a benzophenone sensitizer (E). The content of the benzophenone sensitizer (E) is 150 pts.mass or more relative to 100 pts.mass of the photopolymerizable initiator (D).SELECTED DRAWING: Figure 1 【課題】本発明は、着色パターンの密着性や残膜率が良好なだけでなく、優れた断面形状や直線性を両立するカラーフィルタ、カラー液晶表示装置を提供することを目的とする。【解決手段】赤色顔料（Ａ）と、バインダー樹脂（Ｂ）と、光重合性化合物（Ｃ）と、光重合性開始剤（Ｄ）、及びベンゾフェノン系増感剤（Ｅ）とを含む着色組成物であって、前記ベンゾフェノン系増感剤（Ｅ）の含有量が光重合性開始剤（Ｄ）１００質量部に対して１５０質量部以上を含むことを特徴とする感光性着色組成物により、上記課題は解決する。【選択図】図１
