1. A light-shielding resin composition comprising:
a light-shielding pigment which is one or more selected from the group consisting of metal nitride-containing particles containing an atom A and metal oxynitride-containing particles containing the atom A; and
a resin,
wherein the light-shielding pigment contains at least one of a nitride or an oxynitride of a transition metal having an electronegativity of 1.22 to 1.80, among transition metals of groups 3 to 7, and
the atom A is hafnium, and is an atom different from the transition metal.
