Abstract: A protective film peeling apparatus includes a peeling tape, a tape support portion disposed under one side of the peeling tape, a first pressing portion which is disposed on the one side of the peeling and fixes the one side of the peeling tape to the tape support portion, a second pressing portion which is disposed on another side of the peeling tape and presses and attaches the another side of the peeling tape to one side of a dummy portion of a protective film on a panel, and a grip portion disposed on the dummy portion. The tape support portion and the first pressing portion peel the one side of the dummy portion and a predetermined portion of the dummy portion, and the grip portion peel a remaining portion of the dummy portion.

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.
