BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge display device, and more particularly, to a direct current discharge display device capable of preventing leakage discharge between discharge cells cel1.

In general, the anode and cathode electrodes constituting the discharge cell are formed so as to face the electrode plate while maintaining the required interval, while forming the electrode group on the front plate and the back plate in parallel in the longitudinal direction and the transverse direction, respectively, I) For a direct current type discharge display device which is configured to display by discharge light emission occurring at the opposite parts of the electrodes of the electrode group, a partially enlarged plan view is shown in FIG. 1, and a cross-sectional view thereof is shown in FIG. The following briefly describes this with reference to the drawings.

In FIG. 1, the direct current discharge display device forms a first electrode group 12 on the rear plate 10 in parallel in a lateral direction at a predetermined interval, and the first electrode group 12 is formed at one end of the first electrode group 12. The first electrode group 12 extends from the first electrode group 12 to form a terminal 12 ′ of the first electrode group, and is longitudinally formed on the back plate 10 on which the first electrode group 12 is formed. ) And the partition wall group 16 is formed to intersect at a predetermined interval, and the upper surfaces of the partition walls 16a, 16b, and 16c of the partition group 16 are formed to be interviewed with the front plate 11. On the inner surface of the front plate 11 between the partitions 16a, 16b, and 16c, the second electrode group 13 is formed to face the first electrode group 12 so as to face each other. And extending to the second electrode group 13 at one end of the second electrode group 13 to form a terminal 13 ′ of the second electrode group, wherein the barrier ribs 16a, 16b, and 16c are formed. Discharge gas is injected into the spaces 17a, 17b, and 17c between the spaces, and the periphery is sealed with the frit 18.

The direct current discharge display device formed as described above, as shown in FIG. 2, each anode of each of the cathode electrodes 12a, 12b, 12c, and the second electrode group 13 of the first electrode group 12. When the ON voltage according to the display signal is sequentially or simultaneously applied to the wood electrodes 13a, 13b, and 13c, the on voltage is formed at the cross opposing portions between the electrodes of the positive electrode group. A desired display is obtained by obtaining a light-emitting image due to a potential difference of.

Since the cathode electrode and the anode electrode are exposed to the discharge space, it is necessary to prevent leakage discharge between the discharge cells caused by the rapid growth of the discharge. Therefore, in the conventional direct current type discharge display device, in order to prevent the above leakage discharge, the partition group is provided in the longitudinal direction from the back plate side on which the cathode electrode is formed.

However, the partition group formed in the longitudinal direction can prevent leakage discharge between discharge cells adjacent in the lateral direction, but cannot prevent leakage discharge between discharge cells adjacent in the longitudinal direction.

In addition, by forming a partition wall group to cross the cathode electrodes at a predetermined interval from the back plate side on which the cathode electrodes are formed, contamination is caused by a partition paste for which the cathode electrodes at a portion crossing the partition wall group are printed in multiple layers. There was a problem.

Therefore, an object of the present invention was created to solve the above-mentioned problems, and by forming a partition group on the back plate and the front plate where the first electrode group and the second electrode group are not formed, one discharge cell is formed. Disclosed is a direct current discharge display device that can be separated by a group of partition walls.

Still another object of the present invention is to provide a direct current discharge display device capable of preventing the electrode from being contaminated by the partition paste.

In order to achieve the above object, in the construction of the direct current discharge display device according to the present invention, a first electrode group is formed on the rear plate in parallel at a predetermined interval, and the first electrode group is formed on the rear plate on which the first electrode group is not formed. A first electrode group is formed, and a first electrode group side partition wall group having a predetermined height is formed on the rear plate on which the first electrode group is not formed in parallel with the first electrode group at a predetermined interval. Further, a second electrode group is formed on the front plate in parallel at a predetermined interval, and on the front plate on which the second electrode group is not formed, the second electrode group has an arbitrary height in parallel with the second electrode group at a predetermined interval. After forming the barrier rib group, the front plate and the rear plate are combined so that the first electrode group and the second electrode group are perpendicular to each other, and then discharge gas is injected into the space between the front plate and the back plate on which the above-described elements are formed. It is characterized by sealing the surroundings with frit.

The DC type discharge display device formed as described above can prevent the conventional incomplete leakage discharge by separating discharge cells adjacent in the longitudinal and transverse directions by partition groups formed in the longitudinal and transverse directions.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The first electrode on the back plate 10 and the front plate 11 on which the first electrode group 12 and the second electrode group 13 are not formed in order to prevent the electrode from being contaminated from the barrier paste. Partition groups 15 and 14 having arbitrary heights are formed in parallel with the group 12 and the second electrode group 13 at regular intervals. At this time, the cathode-side partition wall group 15 and the anode-side partition wall group 14 are multilayered by thick film printing method using an insulating paste having a thickness of about 60 μm on the back plate 10 and the front plate 11, respectively. do. By the partition groups 15 and 14 formed as described above, the discharge cells composed of the cross-facing portions between the electrodes of the cathode electrode group 13 and the anode electrode group 13 are separated. Here, reference numeral 12 'is a terminal of the first electrode group which extends and is connected to one side end of the first electrode group 12, and likewise, 13' is an extension of and connected to one side end of the second electrode group 13; It is a terminal of a two-electrode group.

In the DC type discharge display device formed as described above, discharge cells composed of the anode electrode and the cathode electrode are separated by crossing points of the partition group formed on the rear plate and the partition group formed on the front plate, respectively, so as to be adjacent in the longitudinal and transverse directions. It is possible to prevent leakage discharge between the discharge cells. In addition, the barrier rib groups may be formed on the back plate and the front plate on which the first electrode group and the second electrode group are not formed, thereby preventing contamination of the electrode from the barrier paste.
