Next, a paste-like low-melting glass 17a (sealing agent) is formed in a line on the glass substrate 11 using a device such as a dispenser (FIG. 28).

Next, the linear low melting point glass 17a
The glass substrate 11 and the glass substrate 12 are adhered to each other so as to be interposed therebetween, and are welded and fired. Thus, the discharge space 100 between the glass substrate 11 and the glass substrate 12 is sealed from the outside (FIG. 29).

In the gas discharge display panel, an image is formed on the front side of the glass substrate 11 based on the luminous discharge of the discharge space 100 formed on the back side of the glass substrate 11 (between the glass substrate 11 and the glass substrate 12). Is displayed. Glass substrate 11
By sealing the discharge space 100 between the substrate and the glass substrate 12 from the outside, light emission discharge is performed without any trouble.

In the gas discharge display panel described above, the linear barrier rib 16 for dividing the discharge space 100 between the glass substrate 11 and the glass substrate 12 into a large number of discharge cells.
(With a width of about 100 μm to 200 μm).
In addition, due to the characteristics of the low-melting glass 17a, the width L1 of the low-melting glass 17a after sealing the discharge space 100 between the glass substrate 11 and the glass substrate 12 from the outside is 3 mm.
It swells to ４4 mm. Therefore, of the entire area of the glass substrate 11, the area (effective display area) through which light generated between the glass substrate 11 and the glass substrate 12 is transmitted is narrowed.

In order to improve the latter structure, a sealant 18 is applied to the side surfaces of the glass substrate 11 and the glass substrate 12 instead of the low melting point glass 17a as shown in FIG. Discharge space 10 between the lower substrate 12
It has been proposed to seal 0 externally. Sealant 1
8 does not intervene between the upper substrate 11 and the lower substrate 12, so that the effective display area is not narrowed by the sealant 18.

The structure shown in FIG. 30 is disclosed in Japanese Unexamined Patent Publication No. 9-507.
No. 958 discloses this in detail. In FIG.
13 is a cathode, 14 is an anode, 15 is a discharge cell, 1
6 is a barrier rib and 19 is a support member.
