PROBLEM TO BE SOLVED: To provide a colored radiation-sensitive composition that can suppress such a phenomenon that color purity of pixels obtained earlier is degraded by infiltration of a colored radiation-sensitive composition in another color into the pixels formed earlier, and to provide a colored cured film, a color filter, a method for forming a colored pattern, a method for producing a color filter, a solid-state imaging element, and a liquid crystal display device using the composition.SOLUTION: The colored radiation-sensitive composition comprises a dye, a photopolymerizable compound, a photopolymerization initiator, and a nonionic surfactant having a partial structure expressed by general formula (1) or (2) shown below and having a weight average molecular weight of 2500 or less and an HLB value of 9.2 to 15.5 by means of Griffin's method. In general formulae (1) and (2), Rand Reach independently represent a hydrocarbon group having 8 or more carbon atoms; and n1 and n2 each independently represent a number of 4 to 25.
