The anti-warping problem of the circuit board causes troubles in assembly. As shown in the first figure, a conventional liquid crystal display device is fixed to the flexible printed circuit board by bonding the flexible printed circuit board 60 by the adhesive tape 50. In the reflective film 71 of the backlight module 70, since the adhesiveness of the adhesive tape 50 is easily deteriorated by temperature, humidity, and time, and the adhesive method is adopted, it is easy to cause problems such as poor adhesion and improper positioning during assembly. Cannot be corrected. In addition, after the liquid crystal display device is left for a period of time, the flexible printed circuit board 60 is easily lifted or raised by the anti-warping elastic force, so that the light-emitting diode 61 on the flexible printed circuit board 60 cannot stably transmit the light source to the light source. The light guide plate of the backlight module 70 further generates a light beam or a light leak, and the adhesive manner of the adhesive tape 50 also increases the thickness of the liquid crystal display device. In addition to the above-mentioned tape fixing, the hole 62 may be digged in the unprinted portion of the flexible printed circuit board 60 to weaken the rebound of the flexible printed circuit board 60, or may be applied with an iron frame (not shown). Fixed, however, because the module is thinner and the parts are shrinking day by day, the internal wiring of the flexible printed circuit board 60 is dense. If the hole 62 is removed on the flexible printed circuit board 60, the stress is not easily accessible, and the iron frame is used for positioning. It is stable, but the manufacturing cost of the iron frame is high, and the thickness of the module is increased, which is disadvantageous for thinning. [New content] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a structure of a liquid crystal display device, which can improve the combination of a flexible printed circuit board and a light guide plate, and avoid the anti-warping elastic force formed by bending.
