介在させることが実用上有効である。An embodiment of the invention is shown in FIGS. 1a and b, namely:
As shown in FIG. 1a, the film-shaped liquid crystal display element main body 11
A lead wire with a needle-like tip on each electrode of the extraction terminal 12
The film portion of the liquid crystal display element main body 11 is clamped and fixed by piercing 13 through and penetrating, and then bending the penetratingly projecting tip as shown in FIG. In this case, in order to avoid the damage of the electrode portion due to the pressure contact between the thin film transparent electrode of low strength and the hard metal wire, and further to make the contact more sufficiently, it is necessary to connect the electrode between the lead terminal portion 12 and the lead wire 13. It is practically effective to interpose the conductive adhesive 14.

It can be inserted through, bent and held. However, when the display capacity is large, the number of lead terminals is large, and the electrode interval is narrow, the conductive adhesive 14 applied by such a method may come into contact with an adjacent electrode, which is a reliability issue. Will be a problem. In such a case, as shown in FIG. 3, the anisotropic conductive adhesive sheet 15 is attached to the entire surface, and the lead wire 13 is heated from above and pressure-bonded to the lead-wire 13. Only the conductivity is generated, and the space where the lead wires 13 are not formed is not conductive, so that an effective connection can be made in the case of a fine lead wire pitch.
