Plasma display panel and display employing the same having transparent intermediate electrodes and metal barrier ribs

A plasma display panel comprising:

• a front substrate provided with parallel first and second display electrodes for each of cells, and transparent intermediate electrodes, each formed in a space between the first and second display electrodes;
• a back substrate provided with address electrodes extended across the first and second display electrodes;
• metal barrier ribs disposed between the front and the back substrate and defining discharge spaces for the cells, the metal barrier ribs having projections formed in portions intersecting the intermediate electrodes to stabilize the intermediate electrodes at a predetermined potential, the entirety of the metal barrier ribs being insulated from the intermediate electrodes;
• and
• fluorescent layers formed in the discharge spaces;
• wherein the metal barrier ribs are disposed relative to the first and second display electrodes such that a capacitance of a crossing portion between the metal barrier ribs and the first and second display electrodes is smaller than a capacitance of a crossing portion between the metal barrier ribs and the intermediate electrodes so that a narrow pulse discharge occurs between the first and the second display electrodes.
