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.

Abstract: A laser apparatus may include a laser generator generating at least one a laser beam, which is used as an input light, an optical system converting the input light, which is provided from the laser generator, into a plurality of pattern lights, and a stage, on which a target object is loaded. The output light may be irradiated onto the target object. The optical system may divide the input light into a plurality of divided lights, and the pattern lights may be produced by constructive interference of the plurality of divided lights. A diameter of each of the pattern lights may be smaller than a diameter of the input light.

Abstract: Provided is a laser device including a light source generating a laser beam, a stage, and a lens assembly disposed between the light source and the stage and irradiating the laser beam to a substrate disposed on the stage. The laser device is capable of irradiating a uniform laser beam over an entire processing area to which the laser beam is irradiated. Thus, the laser device may irradiate a uniform laser beam to not only a center area, but also the edge area of the processing area.
