A black resin film is produced by applying a photosensitive resin composition containing a black pigment, an alkali-soluble polymer compound, an ethylenic unsaturated bond-containing compound and α-aminoalkylphenone or α-hydroxyalkylphenone as a photopolymerization initiator, to a substrate; and subjecting the composition to exposure, development and post-exposure. The post-exposure is performed from both side with 1,300 mJ/cm2 or more in terms of i line.
