    • An apparatus and a method for cutting a substrate, which can prevent glass chips from sticking to the backside of the substrate by bending the dummy region upward and separating the substrate after fixing a dummy region of the substrate using a chuck, and a fabrication method of a liquid crystal display device using the substrate cutting apparatus are provided. An apparatus for cutting a substrate comprises: a conveyor(130) comprising a plurality of rollers(132) on which a substrate treated in a previous process is loaded, a cutting wheel(134) installed below the conveyor to form a predetermined cutting line on the substrate when the substrate is loaded on the conveyor, and a dummy separator(150) installed below the conveyor of the cutting wheel and provided under the predetermined cutting line-formed substrate to separate a predetermined cutting line-formed dummy region from the substrate completely. The cutting wheel is vertically moved under the conveyor to come in contact with the substrate loaded on the conveyor, and rotated round a rotary shaft(135) by a force applied from an external motor to form a predetermined cutting line. The dummy separator comprises a chuck(152), a rotary shaft(154), and a liftable and lowerable part(156).

    • PURPOSE: A glass cutting device is provided for the purpose of enhancing the glass cutting velocity as well as for a massive production of glass, thereby fundamentally resolving the problem of contaminating the cooling water when cooling the cut portion of the glass. The glass cutting device is also provided for the purpose of maximizing the thermal stress subsequent to heating and cooling of the cut portion by limiting the shape of a laser beam for heating the cut portion. CONSTITUTION: A glass cutting device 10 according to the present invention comprises a base member 11 and a table 20 mounted on the base member 11 and rotatable in both directions by a first driving section 21 at a predetermined angle. An arm 13 is installed on the base member 11 so as to be supported by at least one supporter 12. A first slider 30 is installed on the arm 13 so as to be slidable by a second driving section 31. An elevating member 40 is installed on the first slider 30 so as to be elevatable by a third driving section 41. An optical system 50 is installed on the elevating member 40, and a laser generating section 60 is installed on the optical system 50 for emitting laser beams. A cooling section 70 is installed on an upper part of the table 20 for cooling the cut portion heated by the laser beams.
