Plasma display panel

A plasma display panel including a front substrate, a plurality of row electrode pairs arranged in a column direction on a back surface of the front substrate and each extending in a row direction and forming a display line, a back substrate placed opposite the front substrate with a discharge space interposed, and a plurality of column electrodes arranged in the row direction on a surface of the back substrate facing toward the front substrate and each extending in the column direction to intersect the row electrode pairs and form unit light-emitting areas in the discharge space at the respective intersections, said plasma display panel comprising,

• partition walls provided between the front substrate and the back substrate for defining each of the unit light-emitting areas, each of the partition walls comprising,
• vertical walls each positioned between adjacent unit light-emitting areas of the unit light-emitting areas in the row direction and extending in the column direction to form a partition between the adjacent unit light-emitting areas, and
• transverse walls bridging the vertical walls to define a top and bottom edge of the unit light-emitting areas, each transverse wall having an edge part, defining each of the unit light-emitting areas, having a central part located midway between adjacent vertical walls of the vertical walls protruding beyond a part coupled to the vertical wall toward the outside of the unit light-emitting area in the column direction.
