PROBLEM TO BE SOLVED: To reduce or resolve the residual barrier rib charges accumulated in discharge cells, to eliminate the residual barrier rib charges causing an abnormal discharge, to prevent the abnormal discharge and to improve reliability by containing conductive grains in multiple barrier ribs provided in parallel with address electrodes between multiple address electrodes. SOLUTION: A dielectric layer 22 covering phosphor layers provided between barrier ribs 23 and/or address electrodes A1, A2, A3 preferably contains conductive grains 30. The conductive grains 30 are preferably metal grains, and the metal grains are made of Ni or Cr or an alloy containing Ni or Cr, and the average grain size is preferably set to 1-8μm. The percentage content of the metal grains in the barrier ribs or a phosphor layer is set to 0.5-5 wt.%, the conductive grains 30 are made of a conductive oxide, the conductive oxide is a semiconductor doped with impurities in a metal oxide, and the metal oxide is preferably an indium oxide, a tin oxide or a titanium oxide.
