  • Patent number: 8383013
    Abstract: Disclosed herein is a photosensitive paste composition for a plasma display panel (PDP) electrode capable of minimizing edge curl, i.e., a phenomenon in which the edge of an electrode pattern portion is curled during baking and thus improving withstand voltage. The photosensitive paste composition comprises 40 to 55% by weight of a conductive powder, 5 to 15% by weight of an inorganic binder, 35 to 55% by weight of an organic vehicle, and the remaining percentage by weight of a solvent, wherein the inorganic binder is present in an amount of 15 to 35 parts by weight, with respect to 100 parts by weight of the conductive powder. Further disclosed are a plasma display panel (PDP) electrode fabricated using the composition, and a plasma display panel (PDP) comprising the electrode.
