Abstract: A method of manufacturing a flexible display panel includes forming a groove in a first area of a layered structure of the flexible display panel, and bending a portion of the first area including the groove from a plane of a second area of the layered structure. The second area extends from the first area. Forming the groove includes radiating a pulsating laser beam along an imaginary line corresponding to the groove such that an overlap ratio between consecutive pulse spots of the pulsating laser beam is greater than or equal to 0.80 and less than or equal to 0.90.
