In order to confirm that the notebook type can be kept stable after repeated opening and closing, this is part of the reliability test. However, since there is a large space s between the frame body 14 and the liquid 200809317 crystal display panel 12, when the test is performed, the film 黾 crystal substrate 121 and the driving circuit board 122 are relatively displaced, when the liquid crystal display device 1 passes through the host. After the second opening and closing, 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 FIGS. 3A and 3B). As a result, the flexible circuit board 123 may be fatigued due to distortion, and the connection between the flexible circuit board 123 and the thin film transistor substrate 121 may be easily detached or 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.
