Plasma display panel with reduced electrode defect rate

A Plasma Display Panel (PDP) comprising:

• a first substrate;
• a second substrate facing the first substrate;
• a first barrier rib of a dielectric material disposed between the first and second substrates, and defining discharge cells with the first and second substrates;
• upper discharge electrodes, each including an upper discharge unit disposed in the first barrier rib to surround the discharge cell and a terminal unit protruding from the first barrier rib;
• lower discharge electrodes, each including a lower discharge unit disposed in the first barrier rib to surround the discharge cell and a terminal unit protruding from the first barrier rib, the lower discharge electrodes respectively separated from the upper discharge electrodes;
• a first extension barrier rib, separated from the first and second substrates, arranged between the lower terminal unit and the first substrate and completely covers the lower discharge electrodes, to support the lower terminal unit to be in a same plane as the lower discharge units to prevent bending of the lower terminal unit;
• a phosphor layer disposed in the discharge cells;
• and
• a discharge gas filling the discharge cells.
