Estimating the term…
To make it possible to prevent disconnection of the wiring on a driving multilayer flexible circuit board when folding the board, to reliably fold the circuit board, to improve the assemblability and the reliability or a backlight member, and to improve the noise resistance in a clip-chip-type liquid crystal display device using the circuit board, one end of a flexible substrate FPC2 is connected to an end of one transparent glass substrate SUB1 constituting a liquid crystal display element, the intermediate portion of the flexible substrate FPC2 is folded nearby the outside of an end side of the substrate SUB1, the other end of the substrate FPC2 is arranged at the lower side of an end of the substrate SUB1, and an end of a film BFI of the flexible substrate FPC2 is formed into a waved pattern along the folding line.
A liquid crystal display device comprising a flexible circuit board having a conductor layer, one end of which is connected to the surface of a wiring portion at an end of a liquid crystal display element, and an intermediate portion of which is folded, and whose other end is arranged on the lower or upper side of the end of said liquid crystal display element;
A liquid crystal display device comprising a flip-chip-type liquid crystal display element formed by mounting a driving IC chip on the upper surface of a first of two insulating substrates which are superposed on each other with a liquid crystal layer interposed therebetween and at least one of which is transparent, a first printed circuit board arranged on the underside of an end of said first insulating substrate, and a second flexible circuit board connected to a wiring portion on the upper surface at an end of said first insulating substrate;
