なつていた。 With this configuration, it is necessary to take out the metal lead wires one by one for each electrode connection part of the plasma display panel by soldering, and also to solder one end of the metal lead wires on the printed circuit board, making it difficult to assemble. Soldering man-hours account for a large proportion of the cost, which is a major obstacle to reducing the cost of plasma displays, and the large number of soldering points results in a lack of reliability as a display.

FIG. 3 is a cross-sectional view taken along the line A-A in FIG. This figure shows the output terminal portion 11 1 of the module 7 1 of the transparent electrode drive circuit fixed to the back surface of the substrate 3 with adhesive 10 and connected by wire bonding of gold wire 12. Note that the dielectric film is not illustrated in FIG. Here, since the electrode terminal part 4 1 and the output terminal part 11 1 are located toward the back side of the plasma display panel 1, after bonding the gold wire 12 to the electrode terminal part 4 1 , the gold wire is bonded to the output terminal part 11 1 . By bonding the terminals could be connected to each other. After connecting,
To protect the metal joint 12, it was hardened with epoxy resin 13. In FIG. 2, members such as the resin 13 that are less relevant to the gist of the present application are omitted from illustration. In addition, the electrode terminal part 4
1 was formed from silver paste and connected to the transparent electrode 21 inside the fritted glass 14, and the connection part pitch was 1.27 mm, the terminal part width was 0.8 mm, and it was formed by printing. By forming the output terminal portion 11 1 of the drive circuit 7 1 with a pitch of 1.27 mm, it was possible to bond it smoothly to the electrode terminal portion 4 1 .
The signal input to the drive circuit 7 1 is input from the signal input terminal section 11 2 , but the connection to the lead pattern wired with silver paste on the back of the panel is the same as the output terminal section 11 1 , so it will be omitted. .

ついた。 FIG. 4 is a sectional view taken along line B-B in FIG. 2, and shows an electrode terminal portion 4 2 on the second substrate 3 having an electrode 31 facing the transparent electrode 21 on the first substrate 2.
is connected to the output terminal portion 11 3 of the electrode drive circuit 7 2 on the second substrate 3 fixed to the back surface of the second substrate 3 with an adhesive 10 by bonding with a gold wire 12. It shows. Again, the dielectric film is not shown. Here, the electrode terminal section 4 2 and the output terminal section 11 3 are positioned in the opposite direction to that in FIG. 3, that is, toward the surface of the plasma display panel 1, so that they can be connected by wire bonding. . However, in this case, since the signal input terminal section 11 4 cannot be bonded, the metal lead 15 is soldered to the input terminal section 11 4 in advance, and after the output terminal section 11 3 is processed, the metal lead 15 is connected to the silver pattern on the back of the panel. was soldered. Since the drive circuit section 72 is constructed using a hybrid IC and is designed to have a much smaller number of input terminals than the number of output terminals, the number of man-hours required to solder the output terminals is negligible. Note that the details of the forming method other than those described above are the same as those described in FIG. 3, and will therefore be omitted. In this way, by locating the terminals of the plasma display panel and the terminals of the drive circuit in the same direction and connecting both terminals using wire bonding, which requires less man-hours, it is possible to The number of man-hours required for connection, that is, the number of man-hours required for wiring, is drastically reduced, and plasma display
It is no longer necessary to drop the panel leads onto the printed circuit board, leading to a reduction in printed circuit board material costs.
従つてこの考案による時には、以上説明したよ

付帯効果を有する。 Therefore, as explained above, when this invention is adopted, the external size of the unit is made more compact due to cost reduction and the elimination of the printed circuit board, which has the additional effect of being able to meet the strong demand for space reduction in the market. .
