An optimized paste composition and green sheet form a dielectric layer of a plasma display panel. A plasma display panel is formed by (a) preparing a green sheet of a film-forming material layer formed by applying a paste composition containing PbO-based powder, a binder resin, a dispersing agent, a plasticizer, and a solvent onto a supporting film; (b) transferring the film-forming material layer of the green sheet onto a substrate with electrodes by using a heating roller; and (c) sintering the film-forming material layer transferred onto the substrate. The result is an excellent dielectric layer formed with minimal processing time, and the dielectric layer has good resistance to high temperature and high pressure.
