Abstract

PURPOSE:To prevent the contact failure of a conductive pattern and an LCD panel terminal and the damage of an LCD panel by providing a press-contacting glass plate on a conductive pattern part of an LCD driving substrate, interposing an anisotropic conductive film between the conductive pattern and the LCD panel terminal, and connecting them by heating pressing them from the back part of the press-contacting glass plate. CONSTITUTION:On an LCD panel 1, an LCD panel terminal 7 is drawn out, and on an LCD driving substrate 2, a conductive pattern 6 is provided so as to correspond to the LCD panel terminal 7. Subsequently, the LCD driving substrate 2 is hollowed out by a part connected to the LCD panel terminal 7 of the conductive pattern 6, and a press-contacting glass plate 3 is fitted in. Next, between the LCD panel terminal 7 and the conductive pattern 6, an anisotropic conductive film 4 is interposed and both of them are superposed, heated and pressed from the upper part of the press- contacting glass plate 3, and the LCD panel terminal 7 and the conductive pattern 6 are connected electrically. In such a way, a problem of a contact failure of the conductive pattern and the LCD panel terminal is settled, and also, the LCD driving substrate can be manufactured easily.
