  • Patent number: 8901225
    Abstract: A photosensitive resin composition which can impart insulating properties and light-shielding properties against light having a wavelength lying in an ultra-violet range, a visible range and a near-infrared range to a substrate more readily when applied onto the substrate, wherein the substrate has such properties that the permeability to light having a wavelength of 400 to 900 nm inclusive is less than 3.0% and the maximum value of the permeability to light having a wavelength of longer than 900 nm and not longer than 1300 nm is 3.0% or more. The photosensitive resin composition is characterized by comprising (a) an alkali soluble resin, (b) a specific tungsten oxide and/or a specific composite tungsten oxide, (c) a photopolymerizable compound having at least two polymerizable groups, (d) an oxime-type photopolymerization initiator, and (e) a solvent.
