Abstract
A technique for achieving both discharge voltage reduction and discharge stabilization in a PDP and the like is provided. This PDP manufacturing method includes, for a structure of a front plate structure (11) to be exposed to a discharge space (30) to be filled with a discharge gas, a step of forming a first layer (4) having an effect of discharge protective layer on a dielectric layer (3), a step of forming a second layer (5) for protecting the first layer on the first layer, and a step of forming a third layer (6) of a powder for discharge stabilization to be exposed to the discharge space (30), the steps being performed in vacuum manufacturing process. And, the structure is made such that a surface of the first layer is exposed to the discharge space (30) by a step of removing the second layer by an aging discharge in the discharge space (30).
