no. 1 Embodiment approach
[0072] 1-1 Structure of PDP
[0073] FIG. 1 is a configuration diagram of a PDP according to the first embodiment. Fig. 1(a) is a schematic sectional view along the thickness direction of the panel, and Fig. 1(b) is a front view of the panel.
[0074] In addition, the overall structure of the PDP is the same as the above-mentioned structure in FIG. 21, so the difference from the conventional structure will be mainly described here.
[0075] Here, as an example, the PDP1 is regarded as a 42-inch class size of the NTSC standard, but the present invention is of course also applicable to other standards and sizes such as XGA and SXGA.
[0076] The structure of the PDP 1 shown in FIG. 1 is roughly divided into a front panel FP and a back panel BP whose main surfaces are arranged to face each other.
[0077] On one main surface of front panel glass 10 serving as a substrate of front panel FP, plural pairs of display electrodes 4 (scan electrodes 5 and sustain electrodes 6 ) are fo...
no. 2 Embodiment approach
[0171] 3 is a cross-sectional view schematically showing the structure of a PDP in a second embodiment.
[0172] The second embodiment is characterized in that the sealing layer 17 is composed of two layers, the first sealing layer 176 and the second sealing layer 177, and the outer sealing layer (second sealing layer) is composed of two different layers in the thickness direction of the panel. The thin film layers 1771, 1772 are stacked alternately.
[0173] The first sealing layer 176 is made of the highly airtight material described in the first embodiment.
[0174] On the other hand, the second encapsulating layer 177 is characterized in that two materials selected from organic materials, inorganic materials, and metal materials are laminated alternately as thin films 1771 and 1772 in the thickness direction of the panel. The second encapsulating layer 177 having such a multilayer film structure has a very high air density and is less permeable to moisture and oxygen than...
no. 3 Embodiment approach
[0180] Fig. 8 is a configuration diagram of PDP 101a according to the third embodiment. Among them, FIG. 8( a ) and FIG. 8( b ) show a cross-sectional view in the thickness direction of PDP101a and a schematic front view of PDP101a, respectively.
[0181] The difference between the third embodiment and the above-mentioned first and second embodiments is that, in the sealant layer 18a arranged around the outer peripheries of the two panels FP, BP, the outermost peripheral region has a bonding function along the thickness direction of the panels. Three layers of layer 181a, airtight layer 182a, and adhesive layer 183a are laminated in the same order. On the other hand, the inner region surrounded by the three-layer structure constitutes an integrated adhesive layer 184a.
[0182] As in the first and second embodiments, the sealing layer 18a is sealed simultaneously with the sealing process in a reduced-pressure atmosphere filled with discharge gas inside the chamber.
