    Abstract: A laser machining device includes: a broadband light source, which generates a broadband laser beam; a first lens unit to which the broadband laser beam is incident and having a first effective focal length; a second lens unit spaced apart from the first lens unit in a first direction and having a second effective focal length; a beam splitter disposed between the first lens unit and the second lens unit, and which is movable in the first direction and a direction opposite to the first direction within the first effective focal length from the first lens unit, and splits the broadband laser beam passing through the first lens unit into a plurality of sub-laser beams; and a focusing lens spaced apart from the second lens unit in the first direction, and which focuses the sub-laser beams passing through the second lens unit on a substrate.

    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 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 display device includes a display module extending in a first direction, a supporting portion disposed under the display module and which supports a part of the display module, a first driving part connected to a first end of the display module to roll and unroll the display module, a connecting portion connected to a second end of the display module, and a second driving part connected to the connecting portion to roll and unroll the connecting portion. The second driving part unrolls the connecting portion when the first driving part rolls the display module, and the second driving part rolls the connecting portion when the first driving part unrolls the display module.
