Abstract
A plasma display panel production method is provided for producing a plasma display panel including a first substrate, a second substrate opposed to the first substrate, a barrier rib partitioning a space defined between the first and second substrates into a plurality of discharge spaces, and a seal frit portion provided between peripheral inner surface portions of the first and second substrates to seal the first and second substrates. The method comprises the steps of: forming a seal frit portion on one of the first and second substrates, and forming a barrier rib on the second substrate; combining the first substrate and the second substrate with a spacer of the same material as the seal frit portion being provided between the first substrate and a top of the barrier rib; pressing peripheral portions of the first and the second substrates from outside by a pressing member; heating the first and second substrates to a temperature not lower than a softening temperature of the seal frit portion while evacuating the space defined between the first and second substrates; and introducing a discharge gas into the space defined between the first and second substrates after the evacuating step.
