Abstract: A window manufacturing method includes providing a mother substrate on a moving stage, the mother substrate including a cutting line; irradiating substantially simultaneously a first beam and a second beam to the mother substrate to cut the mother substrate and to form a target substrate; separating the target substrate from the mother substrate; and providing an etchant to the target substrate to chamfer the target substrate. The first beam is irradiated to the cutting line of the mother substrate, the second beam is irradiated to a point spaced apart from the cutting line of the mother substrate by a distance, and a pulse energy of the first beam is different from a pulse energy of the second beam.

Abstract: A method of manufacturing a window and a window manufactured by the same are provided. A method of manufacturing a window includes laser cutting a base glass into a preliminary window using first laser light, irradiating, with second laser light, a point spaced apart from an edge of the preliminary window at a first distance, and providing a window including a flat portion and an edge portion by wet etching the preliminary window irradiated with the second laser light. A method of manufacturing a window having a chamfer shape at the edge portion is facilitated.
