Plasma display panel

Abstract

Provided is a plasma display panel that has a reduced noise radiated from around address electrodes by having ground electrodes formed between the address electrodes when using a single scan method. The plasma display panel includes: a first substrate and a second substrate facing each other; a plurality of barrier ribs dividing a space between the first and second substrates into a plurality of discharge cells; a plurality of pairs of sustain electrodes arranged on the first substrate so as to face the second substrate and so that the sustain electrodes in each pair are spaced apart from one another, each pair of the sustain electrodes including a common electrode and a scan electrode; a first dielectric layer covering the pairs of sustain electrodes; phosphor layers disposed on inner walls of the discharge cells; a plurality of address electrodes intersecting the pairs of sustain electrodes in the discharge cells and extending across the second substrate; a plurality of ground electrodes formed between the address electrodes to be spaced apart from the address electrodes; and a discharge gas filled in the discharge cells.
