Abrégé
(EN)
The present invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel comprises a bending area, the bending area is provided with data signal lines. The at least one data signal line comprises at least one metal layer and at least one stress buffer area internally provided with stress relieving members. The data signal lines in the bending area areprovided with the stress relieving members to reduce the bending stress suffered by the data signal lines when the data signal lines are bent, reduce the impedance of the data signal lines and effectively improve the technical problem that the signal lines are broken and cannot perform signal transmission after the data signal lines are bent so as to improve the service life of the flexible display panel.
