Patent ID: 8183773

Claim:
A plasma display panel (PDP), comprising: a front substrate and a rear substrate facing each other; a partition wall interposed between the front substrate and the rear substrate to define a plurality of unit cells, each unit cell including a main discharge space, an auxiliary discharge space, and a step space, the auxiliary discharge space and the step space being on opposite sides of the main discharge spaces along stepped sidewalls of the partition wall; pairs of scanning and sustain electrodes arranged adjacent to the auxiliary discharge spaces and to the step spaces, respectively, bus electrodes of the scanning and sustain electrodes overlapping respective auxiliary discharge spaces and step spaces; address electrodes extending to cross the scanning electrodes at a location adjacent to the auxiliary discharge spaces; a phosphor layer formed at least in the main discharge spaces; and discharge gas filling the unit cell, wherein a distance between outer edges of bus electrodes of a sustain electrode and a scanning electrode of a same unit cell is smaller than a width of the unit cell, the outer edges of the bus electrodes facing away from each other.
