Abstract

An electrode material for a plasma display panel is provided which is capable of preventing an damage to an address electrode caused by a sandblast process while partition walls are formed. A front substrate on which surface-discharge electrodes are formed is arranged so as to face a rear substrate on which address electrodes are formed in a manner in which the address electrodes and the surface-discharge electrodes intersect each other and partition walls are formed in a manner to extend in parallel to the address electrodes. As an electrode material to form the address electrodes in a plasma display panel in which discharge cells are formed between the front substrate and rear substrate, a conductive paste or conductive sheet containing a conductive particle and glass frit and having sandblast resistance, which is higher than that in the partition wall portions, obtained after being baked is used.
