A plasma display panel comprising first and second substrates positioned
substantially parallel to each other, facing each other and separated
from each other by a predetermined distance is disclosed. A plurality of
address electrodes are formed on the first substrate. A first dielectric
layer covers the plurality of address electrodes on the first substrate.
A plurality of barrier ribs having predetermined heights are mounted on
the first dielectric layer, creating discharge spaces between the first
and second substrates. Phosphor layers are formed within the discharge
spaces. A plurality of discharge sustain electrodes are formed on the
surface of the second substrate facing the first substrate and are
positioned perpendicular to the address electrodes on the first
substrate. A second dielectric layer is formed on the second substrate
covering the discharge sustain electrodes. A protection layer comprising
MgO and Ca, Al, Fe and Si dopants covers the second dielectric layer.
