Plasma display panel

A plasma display panel comprising:

• a front substrate;
• a plurality of electrodes arranged on the front substrate;
• an upper dielectric layer covering the plurality of electrodes on the front substrate;
• and
• a rear substrate arranged opposite to the front substrate,
• wherein the upper dielectric layer comprises a convex portion thicker than the surrounding portion and a concave portion thinner than the surrounding portion, and the bottom width of the concave portion is equal to or more than 0.03 times and equal to or less than 0.87 times of the top width of the concave portion.

• and
• a rear substrate arranged opposite to the front substrate,
• wherein the upper dielectric layer comprises a convex portion thicker than the surrounding portion and a concave portion thinner than the surrounding portion, and the shortest distance between the surface of the convex portion and the electrodes is equal to or more than 1.1 times and equal to or less than 24 times of the depth of the concave portion.

A plasma display panel comprising:

• a front substrate;
• a plurality of electrodes arranged on the front substrate;
• an upper dielectric layer covering the plurality of electrodes on the front substrate;
• and
• a rear substrate arranged opposite to the front substrate,
• wherein the angle of an inclined face of the concave portion is equal to or more than 10° and equal to or less than 80° on the basis of the top face of the convex portion.
