Plasma display panel

A plasma display panel comprising:

• a first substrate and a second substrate substantially parallel to the first substrate and apart from the first substrate;
• a barrier rib layer formed between the first substrate and the second substrate and having cylindrical hollow spaces within the barrier rib layer;
• discharge cells formed by the first substrate and the second substrate as upper and lower surfaces of the discharge cell, and walls of the hollow spaces as walls of the discharge cells;
• phosphor layers formed on the first substrate and over portions of the walls within the discharge cells;
• ring shaped first electrodes located between the first substrate and the second substrate, adjacent to the first substrate, and coupled together along a first direction, each of the first electrodes circumscribing one of the discharge cells;
• ring shaped second electrodes located adjacent to the second substrate and positioned apart from the first electrodes along a direction substantially perpendicular to the first substrate and coupled together along the first direction, each of the second electrodes circumscribing one of the discharge cells;
• and
• address electrodes extending in a direction crossing the first direction and distanced from the second electrodes along a direction substantially perpendicular to the first substrate,
• wherein each of the address electrodes includes a protruding portion, the protruding portion being a plate having an outer contour conforming to an inner contour of the second electrodes.
