Photosensitive resin composition, light-shielding film, and display device

Abstract

An objective of the present invention is to provide a photosensitive resin composition and a light-shielding film that can simultaneously achieve high light-shielding properties and a reduction in the reflectivity on both the glass substrate side and the film surface side, while being environmentally friendly by using a very small amount of fluorine, thereby meeting regulations such as those for PFAS. A photosensitive resin composition of the present invention is characterized by containing components (A) to (F) and satisfying the following conditions (i) and (ii) simultaneously. (i) When a cured film of the composition is formed on a glass substrate with an average thickness in the range of 0.5 to 4.0 µm and the film's surface is measured by XPS, the ratio of the peak area of SiO2 to the peak area ASiO (ASiO2 / ASiO) in the peak fitting analysis of the Si2p3 / 2 peak is from 0.10 to 10.0. (ii) The amount of fluorine (F) element relative to the total amount of Si, C, O, and F elements present on the film surface [F / (Si+C+O+F)] is 5.0% or less.
