Abstract:
1. A manufacturing method for a plasma display panel that includes a front substrate having an MgO-containing protective layer on one surface thereof and a back substrate having a phosphor layer on one surface thereof, the manufacturing method comprising: a superposing step of superposing one of the front and the back substrates on the other via a sealing material disposed along peripheral edges of the substrates to sandwich barrier ribs, so that the protective and the phosphor layers oppose each other with a predetermined distance therebetween; a sealing step of sealing the substrates together along the peripheral edges by the sealing material to enclose an inner space between the substrates, while bringing the inner space into communication with an outside of the space through at least one tube provided in one of the substrates; an evacuating step of evacuating the inner space via the tube after the sealing step; and a discharge gas introducing step of introducing a discharge gas containing a Xe gas into the inner space after the evacuation step, wherein the evacuation step includes:
