Abstract: Disclosed is a non-photosensitive black electrode composition and a plasma display panel having a black electrode formed using the composition. The black electrode for the plasma display panel includes the non-photosensitive composition, thus yellowing does not occur on electrodes but conductivity to a transparent electrode layer is desirably assured even though typical conductive powder and various types of black pigments are used. It is possible to conduct patterning using a photolithography process due to the simultaneous development of black and bus electrodes, which can act as electrodes due to simultaneous sintering. Since it is non-photosensitive, it is possible to use various types of black pigments, thus the material cost is reduced.
