Abstract
Abstract Disclosed is a photosensitive resin composition for use in a light-shielding film, comprising a photosensitive resin and a light-shielding coloring material, wherein light transmission properties after formation of the light-shielding film are controlled by the light-shielding coloring material so that (i) the light transmission through the light-shielding film is 1% or more in at least one wavelength of a light wavelength region of from 330 nm to less than 425 nm, and (ii) the light transmission through the light-shielding film is 2% or less in a light wavelength region of from 425 to 650 nm.
