An exemplary PDP according to an embodiment of the present invention includes first and second substrates, an address electrode, first and second barrier ribs, first and second electrodes, and a phosphor layer. The first and second substrates face each other, the address electrode is formed on the first substrate and extends in a first direction, the first barrier rib is formed on the first substrate and partitions a plurality of first discharge cells, the first barrier rib includes first barrier rib members, disposed in a second direction crossing the first direction, and second barrier rib members, disposed in the first direction. The first and second electrodes extend along the second direction and are disposed in the first discharge cells, corresponding to the first barrier rib members. The second barrier rib is formed on the second substrate and partitions second discharge cells that correspond to the first discharge cells. The second barrier rib includes third barrier rib members, corresponding to the first barrier rib members and protruding towards the first substrate, and fourth barrier rib members, corresponding to the second barrier rib members and protruding towards the first substrate. The phosphor layer is formed in the discharge cells on the second substrate.
