  • Publication number: 20040070342
    Abstract: A method of manufacturing a plasma display panel, which comprises the steps of filling a barrier rib-forming paste containing glass frit in a barrier ribs-forming intaglio and concurrently forming a paste layer having a constant thickness on the intaglio, superimposing a substrate on the barrier ribs-forming intaglio filled with the barrier rib-forming paste containing glass frit to thereby transfer the barrier rib-forming paste onto the substrate, and heating the barrier rib-forming paste that has been transferred to the substrate, thereby burning out existing organic components and concurrently sintering the glass frit to thereby form the barrier ribs and dielectric layer. The plasma display panel manufactured by this method is featured in that the barrier ribs and the dielectric layer are formed using the same barrier rib-forming material containing a low melting point glass frit.
