Zusammenfassung:	PURPOSE:To prevent the defective connection by connecting a flexible printed board to the terminal of a liq. crystal panel substrate and irradiating the vicinity with UV to cure the resin coating the joint. CONSTITUTION:A flexible printed board 14 of polyethylene terephthalate and polyimide is electrically connected to the terminal 2 formed on a liq. crystal panel substrate 1, and the printed board 4 is previously irradiated with UV. The joint is coated with an UV-curing resin 5 and again irradiated with UV to cure the resin. Consequently, the reinforcing effect is improved, adhesion strength is increased, and the galvanic corrosion is reduced. Accordingly, the joint is hardly broken even if expansion or contraction is caused due to heating or cooling when the device is used or the external force is exerted thereon.
