A dielectric composition and a fabrication method for a dielectric layer in
a plasma display panel, by which contrast of the plasma display panel can
be improved through simple fabrication processes. The dielectric
composition for the dielectric layer in the plasma display panel
comprises: a glass of P.sub.2 O.sub.5 --B.sub.2 O.sub.3 --ZnO group; and a
filler consisting of Nd.sub.2 O.sub.3.
