A plasma display panel reduces a resonance space between a frit and dummy partition walls so as to suppress noise and smoothly supply and exhaust a discharge gas. The plasma display panel includes a front substrate and a rear substrate that face each other, address electrodes and display electrodes that are spaced apart from each other and each extend along directions intersecting each other between the front substrate and the rear substrate, and partition walls that form a display region while partitioning a plurality of discharge cells and form a non-display region along a periphery of the display region between the front substrate and the rear substrate. The non-display region includes a first dummy area in which dummy cells are partitioned by dummy partition walls extending from partition walls disposed in the display region, and a second dummy area in which dummy cells are partitioned by dummy partition walls spaced apart from the first dummy area.

Plasma display panel

A plasma display panel including a front substrate, a rear substrate, a display area, a non-display area including a dummy region, and a plurality of rib members is provided. The dummy region includes a first barrier rib region extending along a first direction and including portions of at least some of the plurality of barrier rib members, a second barrier rib region extending along a second direction and including portions of at least some of the plurality of barrier rib members, and at least one sector region. The sector region includes at least one sector barrier rib member extending along a direction other than the first direction and the second direction and connecting at least one portion of at least one of the barrier rib portions in the first barrier rib region to at least one of the barrier rib portions in the second barrier rib region.

Disclosed is a plasma display panel including a first substrate and a second substrate provided with a predetermined gap therebetween, and disposed substantially parallel to each other; a plurality of address electrodes formed on the first substrate; a first dielectric layer formed on a front surface of the first substrate, covering the address electrodes; a plurality of barrier ribs mounted on the first dielectric layer with a predetermined height to provide a discharge space; a phosphor layer formed within the discharge space; a plurality of discharge sustain electrodes provided on a front surface of the second substrate facing the first substrate, and disposed generally perpendicular to the address electrodes; a second dielectric layer formed on the front surface of the second substrate, covering the discharge sustain electrodes; and a passivation layer coated on the second dielectric layer, comprising MgO and dopant elements Si and Fe.

In a plasma display panel, a scanning electrode and a common electrode are alternately formed in strips and parallel to one another on a lower surface of a front substrate. A bus electrode is formed on lower surfaces of the respective scanning and common electrodes to have a narrower width than that of each of the scanning and common electrodes. A black matrix layer is formed of the same insulative material to be parallel to the electrodes at a boundary area between neighboring discharge cells, in which each cell is constituted by a discharge space including a pair of the scanning electrode and the common electrode, and between the scanning and common electrodes and the bus electrode, on a lower surface of the front substrate.
