As explained above, the present invention uses a metal strip clad with aluminum, which is bonded to an electrode terminal made of aluminum by ultrasonic bonding, and further fixed with crystallized glass, unlike the conventional example. This prevents crystallized glass from penetrating between the electrode terminal and the metal strip and causing electrical continuity to be lost, which helps improve manufacturing yield.

ことは言うまでもない。 In the above-mentioned embodiment, the entire one side of the metal strip 22 was clad with aluminum 4, but it goes without saying that the metal strip 22 may be partially clad only at the portion to be bonded to the electrode terminal. Furthermore, it goes without saying that the substrate on which the metal strip is fixed with crystallized glass may be the insulating substrate having the drive circuit, rather than the glass substrate having the display section. Further, in this embodiment, a glass plate is used as the insulating substrate having the drive circuit, but it goes without saying that a forsterite substrate may be used as in the conventional example.
