Apparatus for manufacturing display device with suction unit

A method for manufacturing a display device, the method comprising:

• placing a target substrate on a stage unit;
• and
• irradiating a laser beam onto the target substrate along a cutting line to cut the target substrate, injecting air from the top toward the cutting line of the target substrate, and sucking the air at an outside of the cutting line,
• wherein the injecting of the air is performed by an air blower,
• wherein the sucking of the air is performed by a suction unit,
• wherein the suction unit comprises a main body including an outer box with top and bottom openings and an inner cup disposed in the outer box;
• and a lower plate coupled to a lower end of the outer box and including a through hole,
• wherein an inner end of the lower plate defining the through hole and a lower end of the inner cup define a suction inlet which is opened downward, and
• wherein the sucking of the air is performed through the suction inlet.
