Abstract

The present invention is a photosensitive resin composition for absorbing blue LED light that has been transmitted through a cured photoresist film containing quantum dots capable of emitting red or green fluorescence, the composition containing: (A) an acrylic resin having a (meth)acryloyl group in a side chain; (B) a dye having a maximum absorption wavelength at any wavelength of 490 to 430 nm; (C) an oxime-based photo-radical generator; (D) a surfactant; and (E) a solvent. This can provide: a photosensitive resin composition capable of easily forming a film having high lithography resolution and favorable blue light absorption property; a photosensitive resin film and a photosensitive dry film obtained by using the photosensitive resin composition; patterning processes using these; and displays obtained by using the photosensitive resin composition.
