Document Type and Number:
Japanese Patent JP7029546
Kind Code:
B2
Abstract:
A light-shielding composition includes a light-shielding pigment, a resin, a polymerizable compound, which is a low-molecular-weight compound containing an ethylenically unsaturated group, and a polymerization initiator, in which the light-shielding pigment contains an inorganic particle, and an inorganic compound coating the inorganic particle, the inorganic particle contains one or more nitrogen-containing metal compounds selected from the group consisting of zirconium nitride, zirconium oxynitride, vanadium nitride, vanadium oxynitride, niobium nitride, and niobium oxynitride, the inorganic compound contains a silicon atom, and a contained atom number ratio of a total content of metallic atoms, which are selected from the group consisting of a zirconium atom, a vanadium atom, and a niobium atom, to a content of the silicon atom in a surface of the light-shielding pigment, as determined by X-ray photoelectron spectroscopy, is greater than 1.0.
