布していた。Conventionally, this type of UCD drive board and the terminals of the LCD panel have been made of synthetic resin as shown in FIGS. 3 (a) and 3 (b).
A conductor pattern 6 is provided on the LCD drive substrate 2 so as to correspond to the LCD panel terminal 7, and the anisotropic conductive film 4 is interposed between the conductive pattern 6 and the LCD panel terminal 7 so as to be superposed.
The electrically conductive pattern 6 and the LCD panel terminal 7 were connected to each other by being heated and pressed from above the LCD drive substrate 2 so as to be electrically conductive. Further, the moisture-proof resin 3 was applied to the anisotropic conductive film 4 in order to prevent the anisotropic conductive film 4 from absorbing moisture in the air.

う欠点があった。In the above-described conventional method for connecting the LCD drive substrate, the anisotropic conductive film 7 is used for the conductive pattern 6 and the LCD panel terminal 7.
Since the moisture-proof resin 3 is installed and connected to the inside, the moisture-proof resin 3 is inserted between the conductive pattern 6 and the LCD panel terminal 7. Therefore, there is a drawback in that due to the change in ambient temperature, the thermal expansion of the moisture-proof resin 3 applies a stress that draws the conductive pattern 6 and the LCD panel terminal 7, resulting in poor contact.
