Abstract:
A PDP manufacturing method, for manufacturing a PDP comprising a front plate and a back plate, on at least one of which discharge electrodes have been arranged and on at least one of whose inner surfaces a blue phosphor layer containing BaMgAl10O17:Eu has been formed, the front and back plates being sealed together so that an inner space is formed therebetween, and an aging process then being performed by applying a required discharge voltage to the discharge electrodes while a discharge gas is present in the inner space,the aging process comprising: an introducing process for newly introducing discharge gas with a partial steam pressure of no more than 15 Torr into the inner space from outside; and an evacuating process for evacuating the discharge gas from the inner space, a discharge produced when a required discharge voltage is applied to the discharge electrodes being divided into a plurality of discharge periods, and the introducing process being performed together with the evacuating process in intervals between discharge periods, enabling the discharge gas to be circulated through the inner space.
