Abstract:
1. A plasma display panel comprising: a first substrate and a second substrate facing each other; a plurality of barrier ribs on the second substrate between the first substrate and the second substrate forming a plurality of main discharge spaces and a plurality of auxiliary discharge spaces along a stepped surface of the barrier ribs, each of the barrier ribs comprising a base unit and a protrusion unit protruding from the base unit, the base unit having a relatively large width in comparison to a width of the protrusion unit; pairs of scan electrodes and sustain electrodes extending on the first substrate, the scan electrodes at locations overlapping with or adjacent to the auxiliary discharge spaces; a plurality of address electrodes for generating address discharges together with the scan electrodes; a plurality of phosphor layers respectively in the main discharge spaces; and a discharge gas in the main discharge spaces and the auxiliary discharge spaces, wherein the phosphor layers are not coated inside the auxiliary discharge spaces.
