Abstract

A method for fabricating a flat, light-emitting display panel includes the steps of applying frit seal to the pin electrodes in a state of pressing the rear panel against the front panel to keep them in contact with one another using a flat plate having an opening formed at a position corresponding to each of the pin electrodes; drying the frit seal to fix provisionally the rear panel to the front panel; detaching the flat plate from the both panels; applying frit seal to an end of the front panel and a side face of the rear panel; and burning the whole of components. The sequence of the application of the frit seal to the pin electrode and the application of the frit seal to the end of the front panel and the side face of the rear panel may be altered. The frit seal having flowability less than the frit seal applied to the pin electrode is applied to the end of the front panel and the side face of the rear panel.

Dependent claims

A method for fabricating a light-emitting display panel, the light-emitting display panel including a transparent front panel having a plurality of pin electrodes projecting from a surface thereof, a rear panel having a plurality of slit-shaped holes and a plurality of recesses, each of the plurality of recesses being a discharging space for each of a plurality of display cells, respectively, the rear panel being positioned parallel to the front panel, and each of a plurality of a pair of cell-type electrodes being positioned on the surface of the front panel corresponding to each of the plurality of recesses of the rear panel, respectively, the method comprising:

applying frit seal to the plurality of pin electrodes and a respective periphery thereof when the rear panel and front panel are pressed against one another using a flat plate such that the rear and front panels contact each other and the plurality of pin electrodes penetrates the rear panel through the plurality of slit-shaped holes, respectively, the flat plate having a flat face and each of a plurality of openings formed at a position corresponding to each of the plurality of pin electrodes, respectively;
drying the frit seal to fix the rear panel to the front panel provisionally;
detaching the flat plate from the front and rear panels;
applying frit seal to end sections of the front panel and side faces of the rear panel;
and
burning the frit seal.
