A resin composition for forming a lower layer film of a color filter capable of forming a cured film having excellent solvent resistance, heat resistance and transparency and capable of suppressing the generation of residue of a color resist when forming a color filter on the cured film to provide. [MEANS FOR SOLVING PROBLEMS] A homopolymer or copolymer having a structural unit represented by the following formula (1), an acid compound, a solvent and a color filter containing a crosslinking agent in an amount of 0 mass% to 35 mass% based on the solid content in the resin composition A resin composition for forming a lower layer film. (Wherein R 0 represents a hydrogen atom or a methyl group, R 1 represents a hydrocarbon group having 1 to 6 carbon atoms and having at least one hydroxyl group as a substituent, and the hydrocarbon group having 1 to 6 carbon atoms may further include an ether bond You can have it.) |
