Abstract: This application provides a flexible display panel which includes a first flexible substrate, a second flexible substrate disposed opposite to the first flexible substrate, and a cut protection layer. The cut protection layer connects the edge of the first flexible substrate and the driving circuit connection layer. When the substrate in the cut region is cut by using laser, the cut protection layer will absorb a part of the excessive laser energy to reduce the risk of damaging the metal routing in the driving circuit connection layer by sacrificing itself when laser cutting is performed on the substrate at the side of the cut region of the flexible TFT-LCD and achieve the effect of protecting the metal routing in the cut region, thereby ensuring the display effect of the flexible TFT-LCD display panel.
