Abstract
A light shielding component with low gloss, high blackness, and excellent processability is provided. A light shielding layer () containing black fine particles (), low refractive index nanoparticles (), and a resin composition () is formed on at least one surface of a substrate. The average particle size of the black fine particles () is set to be between 0.1 μm and 50 μm, and the average particle size of the low refractive index nanoparticles () is set to be between 1 nm and 200 nm. Porous carbon is preferred as the black fine particles (), while magnesium fluoride particles and silicon oxide particles are preferred as the low-refractive-index nanoparticles ().
