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.
