Abstract: A method of manufacturing a glass includes forming a first etch protection layer on a first surface of a glass substrate, and forming a second etch protection layer on a second surface of the glass substrate; removing a part of the first protection layer and a part of the second protection layer by applying a laser pulse penetrating the glass substrate from above the first surface of the glass substrate; forming a cut part in the glass substrate by etching the glass substrate using an etching solution; and removing the first etch protection layer and the second etch protection layer. The second surface is opposite to the first surface.

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: An embodiment of the disclosure provides an optical panel cutting device, including: a light converter that converts an incident beam into a Bessel beam; a projection lens that amplifies energy of a beam outgoing from the light converter; a beam splitter that splits a beam outgoing from the projection lens; and an objective lens that amplifies a beam outgoing from the beam splitter to cut a panel, wherein the beam outgoing from the objective lens includes a first peak and at least one second peak, and the at least one second peak has a lower intensity than the first peak.
