Patent ID: 7045962

Claim:
A gas discharge panel having (a) a plurality of cells arranged in a matrix, each cell being filled with a discharge gas which is enclosed between a facing pair of substrates, and a plurality of barrier ribs interposed between the pair of substrates, and (b) plural pairs of display electrodes arranged on an inner surface of one of the substrates so as to extend in a row direction of the matrix across the cells, wherein image display is generated by a discharge fired between the plural pairs of display electrodes, each pair of display electrodes comprising: two bus lines, being parallel to each other and extending in the row direction of the matrix; one or more inner protrusions, being arranged within each cell on an inner side of one or both of the bus lines so as to protrude toward an inner side of an opposite bus line; one or more outer protrusions, being arranged within each cell so as to protrude from an outer side of one or both of the bus lines, at least a section of each of the inner and outer protrusions being positioned between two adjacent barrier ribs, wherein the inner the inner surface of the substrate arranged with the plural pairs of display electrodes is covered with an insulating layer, an area of the insulating layer that corresponds to a shortest discharge gap being composed of magnesium oxide and a remaining area thereof being composed of a material having a lower electron emission rate than magnesium oxide.
