Position alignment structure for plasma display panel
To facilitate evaluation of the amount of a deviation in a column direction between a front substrate and a rear substrate upon assembly of a plasma display panel, thereby improving alignment accuracy between the front substrate and the rear substrate and performances of the resultant plasma display panel, there is provided a plasma display panel comprising partition 15 and position alignment-use ribs 20. The partition 15 is formed of vertical walls 15a extending in a column direction and horizontal walls 15b extending in a row direction on a rear glass substrate 13 so as to partition a discharge space S between a front glass substrate 10 and the rear glass substrate 13 in the row and column directions in accordance with unit luminous regions. The position alignment-use rib 20 is formed on the rear glass substrate, and is positioned in cell Ca which is positioned at the outside of the display region of the plasma display panel within spaces partitioned by the partition 15.
