The liquid crystal display panel has at least one wafer (not shown), and some of the wafers are adjacent to the pins of the liquid crystal display panel, that is, the wafers are adjacent to the first exposed portion 324 of the flexible printed circuit board 300. Furthermore, the first exposed region 324 can be a structure of a sheet-like copper layer to disperse or conduct a large amount of static electricity. '° When the flexible printed circuit board 300 and the liquid crystal display module encounter strong electrostatic particles, the electrostatic particles are quickly guided to the first antistatic layer 324, thereby reducing the damage of the electrostatic particles to the circuit, especially when the electrostatic particles are produced. ^ When the wafer is in the vicinity of the wafer, most of the electrostatic particles move toward the first antistatic layer away from the wafer, so that the wafer in operation can effectively reduce the interference and is not prone to abnormal phenomena such as white screen. Since the present invention is formed into the first-naked area 324 and the first-circuit area 322 in the process of fabricating the first circuit layer, the anti-static effect is achieved, so that the tree does not need to be smuggled to make it a component (see FIG. 2). The net copper layer 24G) can greatly reduce the manufacturing power. In order to match the flexible printed circuit board, the first exposed area 324 can also be formed with ^ = 200948223, which is a piece of copper layer 324a and a The mesh copper layer 324b is adapted to be bent in a region where the mesh copper layer 324b is located. In addition, in order to enable the assembled flexible printed circuit board 300 (liquid crystal display module) to be further connected to a specific device (the notebook computer will be exemplified below, but the liquid crystal display module of the present invention can also be assembled to The first circuit layer 32 is formed at one end of the first exposed area 324 to form a bare first bow end 326, and the first lead end 326 is formed by the first circuit layer 32, and the first circuit end 32 is formed by the mobile phone, the personal computer and the personal digital assistant. The foot bonding region S4 is formed outside the flexible printed circuit board 3 . In other words, the first circuit region 322 is located between the first bare region 324 and the first lead terminal 326, and the first bare region 324 and the first lead terminal 326 are opposite to each other on the first surface A1 of the substrate 310. side. In this embodiment, the two outer pin bonding regions S3, S4 of the flexible printed circuit board 300 are located on opposite sides of the substrate 310, so that the lead terminal 326 and the second lead terminal 334 are located on the substrate 31. Relative to both sides; however, the present invention does not limit the relative positions of the two outer pin bonding regions S3, S4. For example, the two outer pin bonding regions S3, S4 may also be located on adjacent sides of the substrate 310. By connecting the first lead terminal 326 to the Motherboard pin of a notebook computer (not shown), the flexible printed circuit board 3 can be used to transmit the image of the computer to the LCD. Display panel to display the written. Generally, the motherboard will be provided with a grounding terminal to discharge the static electricity. Therefore, the first conductive layer 320 of the flexible printed circuit board 300 of the present embodiment can be exposed to form at least one connection region 328 (the multiple figures shown in the figure are only schematic The present invention does not limit the number of ground terminals, so that the connection region 328 is electrically connected to the first bare region 324 12 200948223. When the flexible printed circuit board 300 is connected to the motherboard, the connection area 328 can be connected to the ground end of the motherboard (so the location of the connection area 328 needs to be matched with the ground end position of the motherboard)" and when the electrostatic particles are After the first exposed area 324 is introduced, the static electricity can be quickly introduced into the grounding end of the notebook computer by the design of the connection area 328, and the static electricity can be effectively led out, thereby further improving the antistatic of the flexible printed circuit board 300 and the liquid crystal display module. ability. Referring to FIG. 3A to FIG. 3C respectively, in order to strengthen the bonding strength between the first circuit layer 320 and the first protective layer 340, in this embodiment, an adhesive is disposed between the first circuit layer 32A and the first protective layer 340. The layer 360, the present invention does not limit the arrangement position of the adhesive layer 360, and those skilled in the art can also configure a plurality of adhesive layers 360 on the first circuit layer 320, the substrate 310, and the second circuit layer 330 according to actual design conditions. The position of the second protective layer 350 between the two. In addition, the present embodiment is provided with a reinforcing plate 370 to make the first lead end 326 more easily combined with the pin positioning of the motherboard. The reinforcing plate 370 is disposed on the first protective layer 350 and different from the second circuit layer 332. The surface, and the reinforcing plate Q 370 and the second lead end 334 are located at both ends of the substrate 310. Therefore, in order to further improve the antistatic property of the flexible printed circuit board, the second circuit layer can also be compared with the design of the first circuit layer, and the reinforcing plate is set to the second bare region, and the following will be further illustrated. In addition, for the sake of brevity, members of the same name still use the same reference numerals. 4A to 4C are schematic views of a flexible printed circuit board according to another embodiment of the present invention, wherein FIG. 4B is a side cross-sectional view of the flexible printed circuit board. Referring to FIGS. 4A to 4C, the flexible printed circuit board 400 of the present embodiment is similar to the aforementioned flexible printed circuit board 300 (shown in FIGS. 3A to 3C), and the difference of 3 200948223 is only different in the second circuit layer 330. One end of the two lead terminals 334 is further formed with a bare second exposed region 430, that is, the second circuit region 332 is located between the second bare region 436 and the second lead pad 334, and the second bare region 436 and the second portion The lead ends 334 are located on opposite sides of the second surface A2 of the substrate 31A. As a result, when strong electrostatic particles are encountered in the vicinity of the outer pin bonding region S4, the electrostatic particles are quickly guided to the second bare region 436, thereby damaging the low electrostatic particle wafer and the circuit. Incidentally, the second bare region 436 of the present embodiment is a structure of a sheet-like copper layer, but the present invention does not limit the structure of the second bare region 436.
