Abstract:
A method for manufacturing a plasma display panel is provided. The method includes making a front substrate and a rear substrate individually and applying a low melting point glass paste including non-porous bead onto a portion of the front substrate or the rear substrate so that the applied low melting point glass paste forms a frame-like shape having a height greater than that of the structural member. The method includes assembling the front substrate and the rear substrate in a face-to-face relation with each other and burning the applied low melting point glass paste while vacuuming a discharge gas space between the front substrate and the rear substrate so as to seal the front substrate and the rear substrate.
