Abstract: A black resin composition, a cured film, and a black filter are provided. The black resin composition includes: a black coloring agent (A), an ethylenically-unsaturated monomer (B), a solvent (C), a resin (D), a photoinitiator (E), a UV absorber (F), and a surfactant (G). The resin (D) includes a first resin having a weight-average molecular weight of 2,000 to 20,000. The first resin includes a structural unit having a fluorene ring and two or more ethylenically-polymerizable groups. The UV absorber (F) includes a benzylidene-based derivative.
