Plasma display panel

A method for manufacturing a plasma display panel including a front substrate and a rear substrate that are opposed to each other with a discharge gas space therebetween, and sealed at their peripheral portions with a sealing material, the method comprising:

• preparing the front substrate and the rear substrate;
• discharging a low melting point glass paste as a sealing material from a nozzle of a dispenser to apply the low melting point glass paste onto a peripheral portion of the front substrate or the rear substrate so that the applied low melting point glass paste forms a frame-like shape;
• assembling the front substrate and the rear substrate in face-to-face relation with each other with the applied low melting point glass paste therebetween;
• and
• burning the applied low melting point glass paste to seal the front substrate and the rear substrate at their peripheral portions,
• the low melting point glass paste being applied from the nozzle includes 0.05-2.0 wt % of non-porous glass bead spacers to glass frit and has a viscosity of not more than 60 Pa·s.

A method for manufacturing a plasma display panel including a front substrate and a rear substrate that are opposed to each other with a discharge gas space therebetween, and sealed at their peripheral portions with a sealing material, the method comprising:

• preparing the front substrate;
• preparing a mother glass having a plurality of areas each identical in both a shape and a size with the rear substrate, elements to be formed on the rear substrate being formed in each of the areas;
• discharging a low melting point glass paste as a sealing material from a plurality of nozzles of a dispenser, each nozzle facing each of the areas, to apply the low melting point glass paste onto a peripheral portion of each of the plurality of areas at a same time so that the applied low melting point glass paste forms a frame-like shape, the applied low melting point glass paste including 0.05-2.0 wt % of non-porous glass bead spacers to glass frit and having a viscosity within a range of 40-50 Pa·s;
• temporarily burning the applied low melting point glass paste on the mother glass;
• cutting off the plurality of areas from the mother glass to obtain a plurality of rear substrates;
• assembling the prepared front substrate and one of the plurality of rear substrates thus obtained in face-to-face relation with each other with the temporarily burned low melting point glass paste therebetween;
• and
• burning the temporarily burned low melting point glass paste to seal the front substrate and the rear substrate at their peripheral portions.
