Plasma display panel

A plasma display panel comprising:

• a front plate;
• and
• a rear plate opposed to the front plate, wherein
• the front plate has a display region to generate a discharge between the front plate and the rear plate, and a non-display region provided at an outer periphery of the display region,
• the front plate further has a first electrode, a second electrode provided parallel to the first electrode, and a discharge gap provided between the first electrode and the second electrode,
• the first electrode includes a first transparent electrode,
• the second electrode includes a second transparent electrode,
• the first transparent electrode includes a plurality of first tip portions projecting therefrom,
• the second transparent electrode includes a plurality of second tip portions projecting therefrom,
• a discharge gap between the first tip portions and the second tip portions in the non-display region is substantially equal a discharge gap between the first tip portions and the second tip portions in the display region, and
• a number of the plurality of first tip projection portions and second tip portions in discharge cells in the non-display region is smaller than a number of the plurality of first tip projection portions and second tip portions in discharge cells in the display region.
