Plasma display panel

Abstract

Provided is a plasma display panel that displays images using visible light emitted from phosphor layers formed in discharge cells as a result of discharges in the discharge cells. The plasma display panel includes a first substrate and a second substrate facing each other, a plurality of barrier ribs disposed to define a space into a plurality of discharge cells between the first and second substrates, sustain electrode pairs extending in a direction on the first substrate crossing the discharge cells, address electrodes crossing the sustain electrode pairs, a first dielectric layer covering the sustain electrode pairs, a second dielectric layer covering the address electrodes, phosphor layers formed in the discharge cells, and an adsorption layer formed in the discharge cells to adsorb impurity gasses and moisture in the discharge cells.
