  • Patent number: 6836310
    Abstract: In a liquid crystal display device having a flexible printed circuit board which includes a laminated structure of a pair of flexible films, a plurality of first conductive layers interposed between inner surfaces of the flexible films to be spaced from each other, and a plurality of groups of terminals formed on an outer surface of one of flexible films opposite to the respective first conductive layers, and a liquid crystal display panel which includes a plurality of groups of wirings formed on one of a pair of substrates thereof and connected to the plurality of groups of terminals respectively, the present invention interposes second conductive layers at respective portions spacing the plurality of first conductive layers between the inner surfaces of the flexible films and prevents the one of the pair of substrates from being cracked when the plurality of terminals of the flexible printed circuit board are connected to the groups of wiring of the one of the substrates by compression bonding thereby.
