Abstract
A plasma display panel includes a front substrate, a rear substrate arranged to face the front substrate, barrier ribs for partitioning discharge cells between the front substrate and the rear substrate, and an exhaust hole formed on the rear substrate in an area between the barrier ribs and the seal layer. A distance between the outermost barrier rib and the seal layer is less than a circumferential length of the exhaust hole.

A plasma display panel comprising:
- a front substrate;
- a rear substrate arranged to face the front substrate;
- barrier ribs for partitioning discharge cells between the front substrate and the rear substrate;
- a seal layer for bonding the front substrate and the rear substrate together;
- a separation barrier rib arranged between the barrier ribs and the seal layer and spaced apart from the seal layer and the barrier ribs;
- and
- an exhaust hole formed on the rear substrate in an area between the barrier ribs and the seal layer,
- wherein the sum of a distance between the outermost barrier rib and the separation barrier rib and a distance between the separation barrier rib and the seal layer is less than a circumferential length of the exhaust hole.
