Abstract
A light-shielding paint includes an epoxy group-containing compound, an inorganic fine particle, a coloring agent, and an amine curing agent. The ratio (A'/A) of the mass (A′) of the amine curing agent to the active hydrogen equivalent (A) of the amine curing agent and the ratio (E′/E) of the mass (E′) of the epoxy group-containing compound to the epoxy equivalent (E) of the epoxy group-containing compound satisfy 0.1≤[(A′/A)/(E′/E)]≤0.45.
