Abstract

A plasma display panel which includes a front panel having a front substrates on which display electrodes each having a scan electrode and a sustain electrode disposed to each other with a discharge gap in between are provided in a plurality of columns; and a rear panel having a rear substrate disposed opposed to the front substrate, on which rear substrate barrier ribs for dividing a discharge space formed with respect to front panel are formed, an data electrode is disposed between the barrier ribs crosswise to the display electrodes, and a phosphor layer is disposed between the barrier ribs. Rear panel is split into a plurality of areas along the direction parallel to the data electrode and barrier ribs are formed for each of the split areas, an alignment mark is provided in a place out of the display region at the splitting border of rear panel, and an insulation layer covering data electrode is provided with a cut to have the alignment mark disclosed.

Claims (12)

1. A plasma display panel comprising:

a front panel having a front substrate, on which display electrodes each having a first electrode and a second electrode are provided opposed with a discharge gap therebetween in a plurality of columns; and

a rear panel having a rear substrate disposed opposed to the front substrate, on the rear substrate, barrier ribs being provided for dividing a discharge space formed with respect to the front panel, a data electrodes being provided between the barrier ribs crosswise to the display electrodes, and a phosphor layer being provided between the barrier ribs; wherein,

the rear panel is split along a direction parallel to the data electrodes into a left area and a right area, and the barrier ribs are formed for each of the left and right areas, interconnect electrodes of the data electrodes are formed split in the left area and the right area of the rear substrate with respect to a splitting boarder, an alignment mark for position aligning is provided in a position where the interconnect electrodes of the data electrodes are formed split in the left area and the right area, and the alignment mark is provided in a place out of a display region at the splitting border on the rear panel simultaneously with the data electrode, and an insulation layer covering the data electrode of the rear panel is provided with a cut to have the alignment mark disclosed.

2. A plasma display panel comprising:

a front panel having a front substrate;

display electrodes on the front substrate;

a rear panel having a rear substrate opposed to the front substrate, the rear substrate including a left area and a right area meeting at a border;

data electrodes on the rear substrate oriented crosswise to the display electrodes;

an alignment mark located outside of a display region on at least one of the left and right areas at the boarder;

a plurality of interconnect electrodes comprising: interconnect electrodes on the left area of the rear panel and to the left of the alignment mark; and interconnect electrodes on the right area of the rear substrate and to the right of the alignment mark; and

an insulation layer, covering the data electrode of the rear panel, including a cut-out around the alignment mark such that the alignment mark is not covered by the insulation layer.
