A radiation-sensitive colored composition capable of forming a colored pattern in which contamination of a liquid crystal layer by a colorant is reduced, a colored pattern formed from the radiation-sensitive colored composition, a method for forming the same, and the colored pattern Provided is a liquid crystal display device. The present invention has a polymer, a photopolymerization initiator having two or more sites represented by the following formula (1) in one molecule, and a lactam structure, this isomer ring structure, or a combination thereof. It is a radiation sensitive coloring composition containing a coloring agent. The polymer preferably has a cyclic ether group, a (meth) acryloyl group, or the like. The present invention uses the radiation-sensitive colored composition, a step of forming a coating film on a substrate, a step of irradiating a part of the coating film, a step of developing the coating film irradiated with the radiation, And the formation method of a coloring pattern provided with the process of heating the developed said coating film. (In the formula (1), R X represents a monovalent organic group.) [Selection figure] None |
