A resin composition, a cured film and a black matrix are provided. The resin composition includes an epoxy resin (A), a black coloring agent (B), a photoinitiator (C), a thermal acid generator (D), a polymerizable monomer (E) and a solvent (F). The thermal acid generator (D) includes hexafluoroonium salt. The polymerizable monomer (E) includes a photopolymerizable monomer (E-1), an epoxy resin monomer (E-2) or the combination thereof. Based on a total usage amount of the polymerizable monomer (E) as 100 parts by weight, a usage amount of the epoxy resin monomer (E-2) is 15 to 70 parts by weight. |
