PURPOSE: A radiation-sensitive composition for forming a colored layer is provided to ensure enough phenomenon tolerance even in low exposure and to form pixel and black matrix with excellent solvent resistance. CONSTITUTION: A radiation-sensitive composition for forming a colored layer comprises (A) a coloring agent, (B) a polymer having an oxetanyl group and a polymerizable unsaturated bond, and (C) a photopolymerization initiator. The polymer having an oxetanyl group and a polymerizable unsaturated bond is the polymer having an oxetanyl group and a (meth)acryloyl group.
