Therefore, the user can view the flexible display panel 210 of the flexible display panel toilet in the viewing direction m shown in Fig. 2 to interpret the displayed information. The following is a description of the fabrication of the flexible display panel of the present embodiment. Referring to Figures 3A through 3F, there is no intention to make the pullable display panel of Figure 2. First, referring to Fig. 3A, a substrate is provided, such as glass. Next, referring to FIG. 3B, the flexible display module 210 is formed on the support substrate si and the flexible substrate 211 of the flexible display module is disposed on the support substrate S1. The second surface 21 of the flexible substrate 211 faces the support substrate S1. Then, referring to FIG. 3C, the flexible circuit boards 220 are thermally bonded to the peripheral circuit region 212b by the first isotropic conductive film A3 to electrically connect the flexible circuit boards 220 and the peripheral circuit regions 212b. . Then, the driving devices 23 are thermally bonded to the peripheral circuit region \12b by the second isotropic conductive film A4 to electrically connect the respective driving devices 230 and the peripheral circuit regions 212b. Next, referring to FIG. 3C and FIG. 3D, after the support substrate Sb 201032193 is removed, please refer to FIG. 3E to form a protective material layer 240' on the second surface 211b of the flexible substrate 211.

If the material of the protective material layer 240' is a thermosetting adhesive, the above-described method of curing the protective material layer 240' is to heat the protective material layer 240. Since the protective material layer 240' is a gel, when the protective material layer 240 is formed on the second surface 211b of the slidable substrate 211, the pressure on the second surface 211b of the slidable substrate 211 can be controlled. The flexible substrate 211 can withstand the range. In addition, the manner of forming the protective material layer 24'' on the second surface 211b of the flexible substrate 211 in this embodiment may be coating, spraying or screen printing, so the protective material layer 240 is formed to be flexible. When the second surface 21 lb of the substrate 211 is applied, the pressure applied to the second surface 21 lb of the flexible substrate 211 can also be controlled within a range that the flexible substrate 211 can withstand. The flexible display panel of the embodiment of the present invention and the manufacturing method thereof have at least one of the following or other advantages: 1. Since the cured protective layer is disposed on the second surface of the flexible substrate, The cured protective layer protects the second surface of the flexible substrate. Therefore, when a pressure acts on the cured protective layer, the first circuit layer 2 of the flexible display module is liable to be damaged. In other words, the inside of the flexible display panel of the embodiment of the present invention is protected by the cured protective layer. 201032193 (4) The second material layer is a gel, so when the protective material layer is formed on the surface of the substrate, the pressure on the second surface of the flexible substrate can be controlled by the flexible substrate. 3. Since the protective material layer can be formed by coating, spraying or screen printing, the pressure on the second surface of the flexible substrate can also be controlled by the flexible substrate. Within the scope.
