Plasma display panel comprising a first external electrode for each digit and a second external electrode for each segment

Claim 1

In a plasma display panel for a plurality of identical characters including: first and second supporting members, a plurality of identical sets of character-forming electrodes on said second supporting member, a common electrode for each set on said first supporting member, and means associated with the common electrode to enable a first electric potential to be applied thereto, the improvement which comprises: electroconductive means on said second supporting member in coplanar relation to said character-forming electrodes for connecting corresponding electrodes in each set in series so that corresponding electrodes in each set and the connecting electroconductive means therebetween form a continuous line segment free of branches, and plural lead wires extending from first ends of each of the serially connected character-forming electrodes disposed at one end of said continuous line segment for applying a second electric potential to the corresponding electrodes connected to said each character-forming electrode coincident with said first potential, whereby a potential difference of predetermined magnitude may be produced between the energized corresponding electrodes and a common electrode for a selected set.
