An object of the present invention is to provide a black photosensitive resin composition capable of forming a light-shielding cured product having high solvent resistance even when a baking temperature is low, a method for producing a patterned cured product using the black photosensitive resin composition, a patterned cured product formed from a cured product of the black photosensitive resin composition, and a black matrix formed from the cured product of the black photosensitive resin composition. The black photosensitive resin composition comprises an alkali-soluble resin (A), a specific photo-polymerizable monomer (B), a photo-polymerization initiator (C), and a specific light shielding agent (D).
