Abstract

The invention provides a photosensitive resin composition including a black colorant, a photopolymerizable compound, a resin, a photopolymerization initiator and a solvent, the composition capable of forming a light-shielding color filter having a ratio OD/ODof from 0.5 to 3, where ODis an optical density at a wavelength of 1200 nm and ODis an optical density at a wavelength of 365 nm; and a photosensitive resin composition including titanium black, a photopolymerizable compound, a resin A having an acid value of from 70 to 250 mgKOH/g, a resin B having an acid value of from 26 to 65 mgKOH/g, a photopolymerization initiator, and a solvent.
