The invention relates to a colored radiation-sensitive composition, color filter and color liquid crystal display device. A novel colored radiation-sensitive composition capable of forming a cone pixel with excellent solvent resistance in case of low light exposure is provided. The colored radiation-sensitive composition is characterized in that the colored radiation-sensitive composition contains (A) a colouring agent, (B) a dispersant, (C) an alkali-soluble resin, (D) a multifunctional monomer and (E) a light polymerization initiator, wherein at least one of (b) the dispersant and (d) multifunctional monomer has a caprolactone structure, and (E) the light polymerization initiator contains 2-(4-methylbenzyl)-2-(dimethylamino)-1-(4-morpholinophenyl)butane-1-one.
