ABSTRACT:
A connecting tape for interconnecting wiring lines on a liquid crystal display panel and those on a driver IC is constituted by an insulating tape having wiring layers provided thereon. The wiring layers have a plurality of first pitch group wiring layers on an upper surface of one of end sides of the insulating tape and a plurality of second pitch group wiring layers on an upper surface of the other of the end sides of the insulating tape, with the second pitch group having pitches different from those of the first pitch group wiring layers. The first pitch group wiring layers are adapted to be aligned and connected with wiring lines of the liquid crystal display panel which lines are arranged in the same pitches as those of the first pitch group wiring layers, and the second pitch group wiring layers are adapted to be aligned and connected with wiring lines of the driver IC. There can be a number of different pitch group wiring layers and of different pitch group wiring lines. It is possible to connect one given kind of film carrier type liquid crystal display driver IC with a number of liquid crystal display panels having wiring lines whose pitches are different from those in the liquid crystal display driver IC. This can save costs and time in the fabrication of the product concerned.
