PROBLEM TO BE SOLVED: To provide a photocurable composition having excellent long-term storage stability and satisfying the requirements for sufficient conductivity and black color after calcining without losing excellent adhesion property with the substrate, resolution and calcination property in each step of drying, exposure, development and calcination and to provide a plasma display panel (PDP) having a black layer (lower layer) electrode circuit in the electrode having a black and white double-layer structure by using the above composition. SOLUTION: A first basic embodiment of the photocurable composition contains (A) black inorganic fine particles of ruthenium oxide, ruthenium compound, copper - chromium black double oxide, copper - iron black double oxide or cobalt oxide coated with an inorganic binder, (B) an organic binder, (C) a photopolymerizable monomer and (D) a photopolymerizable initiator. The photocurable composition is applied on the transparent electrode of a front glass substrate, exposed according to a specified pattern, developed and calcined to form the black layer (lower layer) electrode circuit of the electrode having a black and white double-layer structure of the PDP. |
