[Prior Art] At present, liquid crystal display devices have been widely used in notebook computers, digital cameras, digital cameras, personal mobile assistants, and mobile phones. Please refer to FIG. 1 as a conventional notebook computer. The liquid crystal display device 1' generally includes an upper frame 10, a lower frame 11, and a liquid crystal display panel 12 and a backlight module 13 disposed between the upper frame 10 and the lower frame 11. Further, the liquid crystal display device 1 further includes A body 14 is included for fixing the liquid crystal display panel 12 and the backlight module 13. The liquid crystal display device 1 has a pivoting portion 15 pivoted to one side of a host (not shown) to enable the liquid crystal display device 1 to be opened and closed with respect to the main unit.

Usually, the notebook computer usually passes a hinge test before leaving the factory, which is to open and close the liquid crystal display device 1 of the notebook computer relative to the host (not shown) about 20,000 times. In order to confirm that the notebook computer can maintain the stability of various electrical characteristics after repeated opening and closing, this is part of the reliability test. However, since the frame 14 has a large space s between the display panel 12 and the display panel 12, the relative displacement of the thin film transistor substrate 121 and the driving circuit board 122 occurs when the liquid V crystal display device 1 is relatively opposed. After the main body is opened and closed a plurality of times, the flexible circuit board 123 is connected to one end of the thin film transistor substrate 121 to be deformed downward or upward (as shown in FIG. 3A and FIG. 3B). As a result, the pullable circuit board 123 may be fatigued due to distortion, resulting in the connection between the switchable circuit board 123 and the thin film transistor substrate 121 being easily detached or φ broken, so that the signal cannot be transmitted to the thin film. Since the liquid crystal display device 1 forms a defective product and cannot pass the opening and closing test, the production yield of the notebook computer is lowered.

In addition, in the present embodiment, the liquid crystal display device 2 is applied to a single meter, and the structure of the present invention is more applicable to a folding electronic product such as a folding mobile phone or a digital camera (DV). in. The liquid crystal display panel 21 has a thin film transistor substrate 211 and a flexible circuit board 212, and the flexible circuit board 212 is connected to the thin film transistor substrate 211, and the flexible circuit board 212 has a curved section 212a, a curved section 212a is extended from the connection of the flexible circuit board 212 and the thin film transistor substrate 211 to 1344038. In addition, the liquid crystal display panel 21 further has a driving circuit board 213 and a color filter substrate 214 (color filter), and the flexible circuit board '212 is connected to the driving circuit board 213 and the thin film transistor substrate 211, and the color and color The filter substrate 214 is disposed adjacent to one side of the thin film transistor substrate 211.

The frame 23 is fixed to the liquid crystal display panel 21, and the frame 23 has a stopper 231 which is adjacent to the curved section 212a of the flexible circuit board 212. In the present embodiment, the frame 23 has a turning portion 232, and the turning portion 232 is disposed adjacent to the curved portion 212a of the flexible circuit board 212. Further, the supporting member 231 may be integrally formed with the frame body 23. As shown in FIG. 4A, only the blocking member 231 is disposed adjacent to the curved portion 212a of the flexible circuit board 212, so that the blocking member 231 can restrict the flexible circuit board 212 upward (eg, - The deformation shown in the arrow of Fig. 4A can reduce the upward deformation amount of the flexible circuit board 212', so that the flexible circuit board 212 is not easily peeled off or broken by the thin film transistor 'substrate 211' in this embodiment' The stopper 231 is a single body, and the material of the stopper 231 can be a cushioning material.

With the above configuration, the provision of the stopper 231 restricts the flexible circuit board 212 from being deformed upward, so that the flexible circuit board 212 is connected to one end of the thin film transistor substrate 211, and is less likely to be broken or damaged. Referring to FIG. 5A, a liquid crystal display device 3' according to a second embodiment of the present invention includes a liquid crystal display panel 31, a backlight module 32, and a frame body 33. The structure of the liquid crystal display panel 31 and the backlight module 32 is the same as that of the liquid crystal display panel 21 and the backlight module 22 in the first embodiment, and will not be described herein. The frame 33 is fixed to the liquid crystal display panel 31. The frame 33 has a bent portion 331, wherein the liquid crystal display panel 31 has a flexible circuit board 311 and a thin film transistor substrate 312, and the bent portion 331 is adjacent thereto.
