Abstract
A plasma display panel having a dielectric with a stepped structure and a method for manufacturing the same are disclosed. The plasma display panel includes a first panel comprising a plurality of electrode pairs each including a scan electrode and a sustain electrode, and a dielectric layer formed over the electrode pairs, a second panel comprising a plurality of address electrodes arranged to cross the plurality of electrode pairs, and barrier ribs formed on the second substrate, to define discharge cells. The dielectric layer includes recesses respectively arranged between two electrodes arranged in each discharge cell and between two electrodes arranged adjacent to each other at opposite sides of each barrier rib.
