Abstract:
A method of manufacturing a plasma display panel in which a first substrate provided on its inner surface with a plurality of row electrode pairs each extending in a row direction and arranged in a column direction to form display lines, a dielectric layer covering the row electrode pairs and a protective layer for protecting the dielectric layer, is placed opposite a second substrate provided on its inner surface with column electrodes each extending in the column direction and arranged in the row direction, to define a discharge space between the first and second substrates, then a seal is provided around outer edge portions of the first substrate and the second substrate to hermetically seal the discharge space, and then a discharge gas is introduced into the discharge space from a non-display area of the discharge space located outside a display area of the discharge space in which unit light-emitting areas are formed at the respective intersections of the row electrode pairs on the first substrate with the column electrodes on the second substrate, said method of manufacturing the plasma display panel comprising the steps of:providing a pair of discharge electrodes for causing a discharge in the non-display area of the discharge space; applying a voltage between the pair of the discharge electrodes to initiate the discharge when the discharge gas is introduced into the discharge space or alternatively after the discharge gas has been introduced; and placing a gas adsorptive member, formed of a gas adsorbent, in a position facing the discharge space in said non-display area of the discharge space in which the introduction of the discharge gas is provided, wherein said gas adsorptive member is a rib member forming a path for introducing the discharge gas in the non-display area of the discharge space in which the introduction of the discharge gas is provided.
