To obtain the radiation-sensitive composition for the color filter high in film hardness, that the pixel patter is prevented from occurrence of damage and the like due to brushing and the like after development and the pixel superior in adhesion to a substrate and a light shielding layer and surface lubricity is obtained by incorporating a colorant and the like and a photopolymerization initiator containing a specified compound.
The radiation-sensitive composition contains the colorant, a polyfunctional monomer, and the photopolymerization initiator containing the traizine compound represented by the formula and the triazine compound enhances cross-linking density and film hardness at the time of exposing the radiation-sensitive composition to harden it. This photopolymerization initiator contains, further, the biimidazole derivative made of 2,2'-bis-(2,4- dichlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole, that function as a hydrogen donor.
