  • Publication number: 20070278955
    Abstract: A manufacturing method of a PDP includes: a first material filling step for filling recessed portions (41) of a molding die (4) with a first dielectric paste (23A) that forms partitions; a second material application step for applying a second dielectric paste (22A) that forms an address electrode protective layer on a rear substrate (2); a transfer step for pressing the molding die (4) against the second dielectric paste (22A) and then peeling the molding die (4) off from the rear substrate (2); and a firing step. Since the molding die (4) is pressed against the second dielectric paste (22A) that has a fluidity in the transfer step, the first dielectric paste (23A) and the second dielectric paste (22A) can be adhered to each other securely. Accordingly, the partitions having a desired shape can be formed securely and inter-partition portions of the address electrode protective layer can be uniformly formed with a uniform thickness.
