Plasma display panel with address electrode having projections

A plasma display panel, comprising:

• a first substrate and a second substrate facing each other across a discharge space;
• row electrode pairs extending in a row direction and regularly arranged in a column direction on the inner face of the first substrate and each consisting of a first electrode and a second electrode;
• a plurality of column electrodes extending in the column direction and regularly arranged in the row direction on the inner face of the second substrate and forming unit light emission areas respectively corresponding to the intersections with the row electrode pairs in the discharge space;
• and
• a partition wall unit comprising at least a plurality of transverse walls extending in the row direction to partition the discharge space into the unit light emission areas, wherein
• each of the column electrodes is divided into a first electrode portion and a second electrode portion,
• the panel surface of the PDP is made up of a first panel face facing the first electrode portion and a second panel face facing the second electrode portion,
• the transverse wall of the partition wall unit faces a boundary between the first panel face and the second panel face of the panel surface, and
• at least one of the first and second electrode portions of each of the column electrodes has an end located in proximity to the boundary between the first panel face and the second panel face of the panel surface and having a projection that extends out therefrom toward the other electrode portion and is opposite an end of the other electrode portion located in proximity to the boundary between the first panel face and the second panel face;
• wherein the projection is provided at each of the opposing ends of the respective first and second electrode portions of the column electrode, and has a width smaller than a row-direction width of each of the first and second electrode portions, and the projections formed at the respective ends extend out toward the respective other electrode portions and face each other across a required gap in the row direction.
