Abstract:
1. A plasma display panel comprising: a front substrate; a rear substrate opposite the front substrate; a barrier rib that is positioned between the front substrate and the rear substrate to provide a discharge cell, the barrier rib including a first barrier rib and a second barrier rib that cross each other for partitioning the discharge cell; a seal layer that attaches the front substrate to the rear substrate; and an exhaust hole that is formed on the rear substrate in a portion between the barrier rib and the seal layer, the exhaust hole being positioned in a portion that overlaps the discharge cell partitioned by the first barrier rib and the second barrier rib along a shorter side of the rear substrate, wherein a gap between the seal layer and an outermost barrier rib of barrier ribs positioned parallel to the shorter side of the rear substrate is less than a gap between the seal layer and an outermost barrier rib of barrier ribs positioned parallel to the longer side of the rear substrate.
