Patent ID: 6856305

Claim:
A plasma display panel comprising: a first substrate, a second substrate opposed to said first substrate; and a barrier rib disposed between said first substrate and said second substrate, wherein said first substrate comprises a substrate; and a plurality of first electrodes arranged on said substrate along a first direction, extending along a second direction intersecting said first direction, for defining a plurality of display lines extending along said second direction, wherein a plurality of gap portions provided between said plurality of first electrodes include at least a plurality of discharge gap portions corresponding to said plurality of display lines, said first substrate further comprises a dielectric layer disposed on said substrate, covering said plurality of first electrodes; a cathode film opposed to said substrate with said dielectric layer interposed therebetween, having exposed surfaces in areas thereof corresponding to said plurality of display lines; and a discharge inert film opposed to said substrate with said dielectric layer interposed therebetween, having exposed surfaces in areas thereof corresponding to areas between said plurality of display lines, whose secondary electron emission characteristic is lower than that of said cathode film, wherein said exposed surfaces of said discharge inert film and those of said cathode film are adjacent to one another as two-dimensionally viewed, and said discharge inert film is made of an aggregate of fine particles which does not substantially contain any inorganic binder.
