Plasma display panel having dummy barrier ribs

A plasma display panel, comprising:

• a first substrate and a second substrate opposing one another with a predetermined gap therebetween, the first substrate and the second substrate being substantially rectangular in shape with long side edges and short side edges, and being interconnected by frit deposited between the first substrate and the second substrate, said substrates having a predetermined discharge region and predetermined non-discharge regions that surround the discharge region, the predetermined discharge region and the predetermined non-discharge regions being within an area sealed by the frit;
• and
• barrier ribs mounted between the first substrate and the second substrate,
• wherein the barrier ribs are mounted at least partly on the discharge region, and at least partly on the non-discharge regions that are adjacent to the long side edges of the substrates, and wherein at least two of the barrier ribs are mounted at least partly on the non-discharge regions.
