Abstract
A photocuring composition includes black particles (A), black particles (B), an organic binder (C), a photopolymerizable monomer (D), and a photopolymerization initiator (E). The black particles (B) have a volume resistivity lower than the volume resistivity of the black particles (A) and an average diameter larger than the average diameter of the black particles (A).
