  • Patent number: 7470737
    Abstract: A dielectric paste of the present invention contains a binder resin, a cross-linking agent, a thermal polymerization initiator, and an inorganic powder, wherein the content of the thermal polymerization initiator is 3 to 30 parts by weight to 100 parts by weight of the total of the binder resin and the cross-linking agent. A method of manufacturing a plasma display, of the present invention, includes a first step of forming electrode patterns using an electrode paste, a second step of forming a dielectric paste coating film using a dielectric paste, a third step of forming barrier rib patterns using a barrier rib paste, a subsequent step of simultaneously firing at least the electrode patterns, the dielectric paste coating film, and the barrier rib patterns, and a step of performing curing after the second step.
