BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat panel display device, and more particularly, to a flat panel display device in which corrosion of wirings connecting printed circuit boards is prevented.

1 is an exploded perspective view schematically showing a conventional flat panel display apparatus.

Referring to FIG. 1, a display unit is provided on a substrate 1, and a sealing member 2 such as a metal cap is provided to cover the display unit. The first terminal 31 and the second terminal 32 are exposed to the outside of the sealing member 2.

A printed circuit board 5 including a controller IC, a drive IC, a jumper IC, and the like is connected to the sealed flat panel display panel. The connection of the printed circuit board 5 is an anisotropic conductive material that is connected to the first terminal 31 and the second terminal 32, one end of which is connected to the display unit and the other end of which is exposed to the outside of the sealing member 2. The film may be formed by attaching an anisotropic conduction film (ACF), placing the printed circuit board 5, and then pressure bonding the bar with a heating means.

At this time, as shown in Figure 1, the printed circuit board 5 is formed integrally. That is, the printed circuit board 5 is composed of a first circuit board 51 connected to the first terminal 31 and a second circuit board 52 connected to the second terminal 32. 53).

However, in the printed circuit board 5 having the above-described configuration, the first circuit board 51 and the second circuit board 52 are connected to each other by the connecting portion 53 positioned outside the board 1. Accordingly, there is a problem in that the connection part 53 may be broken during the process of pressing and bonding the first circuit board 51 and the second circuit board 52.

In addition, as shown in FIG. 2, in the original plate 50 for manufacturing the printed circuit board 5, the first circuit board 51 and the second terminal (connected to the first terminal 31) ( As the arrangement structure of the second circuit board 52 connected to the 32 is limited as described above, the dead space 54 which cannot be utilized between the first circuit board 51 and the second circuit board 52 is formed. This dead space 54 causes waste of the original plate 50 for the manufacture of the printed circuit board 5, and reduces the working efficiency and increases the manufacturing cost.

In order to solve this problem, as shown in FIG. 3, a method of allowing the first printed circuit board 51 and the second printed circuit board 52 to be provided separately is provided. That is, since the first printed circuit board 51 and the second printed circuit board 52 are not formed integrally but are formed independently, the dead space is generated in the manufacturing of the printed circuit board as shown in FIG. 4. By reducing the waste of raw materials and manufacturing costs can be reduced.

In this case, a means for interconnecting the first printed circuit board 51 and the second printed circuit board 52 should be provided separately, as shown in FIG. 5, which shows an enlarged portion A of FIG. 3. Similarly, the bypass connection line 4 is provided on the substrate 1 and both ends of the bypass connection line 4 are connected to the first printed circuit board 51 and the second printed circuit board 52, respectively. By doing so, the first printed circuit board 51 and the second printed circuit board 52 are connected to each other.

However, in the case of the flat panel display device as described above, the bypass connection line 4 is provided outside the sealing member 2 so as to be exposed to the outside. As a result, when a high voltage is applied to drive the flat panel display device, There was a problem that the bypass connection line 4 is corroded. Therefore, in order to prevent this, the bypass connection line 4 had to be sealed with a separate organic solvent. As a result, a separate process was added, manufacturing cost increased, and there was a problem that a progress defect due to a poor sealing could occur. .
