Provided is a resin composition for forming a color filter underlayer film that can form a cured film having excellent solvent resistance, heat resistance, and transparency, and can suppress generation of residues of color photoresist when forming a color filter on the cured film. Thing.nn n n Color filter containing a homopolymer or copolymer, an acid compound, a solvent, and a relative solid content in the resin composition of 0 to 35% by mass with a structural unit represented by the following formula (1) Resin composition for forming an underlayer film.nn n n (Wherein R 0 is a hydrogen atom or a methyl group, and R 1 as a substituent represents a hydrocarbon group having 1 to 6 carbon atoms having at least one hydroxyl group, and the aforementioned hydrocarbon group having 1 to 6 carbon atoms may further have an ether bond) . |
