摘要： PROBLEM TO BE SOLVED: To suppress capacitive coupling which causes increase in reactive power of a PDP and decrease in driving margin.
SOLUTION: The PDP (plasma display panel) 1 has a plurality of light shielding membranes 10 formed with a spacing between an X electrode 14 and a Y electrode 15 in a non-light-emitting region 16 formed between two pairs of the X electrodes 14 and the Y electrodes 15 (display electrode pair) formed in a front face substrate structure (first substrate structure). The light shielding membranes 10 contains a metal material in common with the metal material constituting the X electrode 14 and the Y electrode 15. Moreover, the light shielding membranes 10 are formed in an island shape with the spacing between mutually neighboring barrier ribs 22 formed in a rear face substrate structure (second substrate structure). By this arrangement, since an area of the light shielding membranes 10 possible to constitute a capacitive coupling part with the X electrode 14, the Y electrode 15, or an address electrode 20 can be made smaller, the capacitive coupling can be suppressed even if a conductive material is used for the light-shielding membranes 10.
