Abstract

An apparatus for manufacturing a display device includes: a stage unit; and a suction unit located above the stage unit, wherein the suction unit includes: a main body including an outer box with top and bottom openings and an inner cup disposed in the outer box; a first air blower disposed above the main body and including a first main pipe extending in a first direction and a second air blower including a second main pipe extending in a second direction intersecting the first direction; a lower plate coupled to a lower end of the outer box and including a through hole; and a suction inlet defined by an inner end of the lower plate defining the through hole and a lower end of the inner cup, wherein the suction inlet is opened downward.

First claim

What is claimed is:

1. 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.

2. The method of claim 1 , wherein the air blower comprises a first air blower disposed above the main body and including a first main pipe extending in a first direction; and a second air blower including a second main pipe extending in a second direction intersecting the first direction.

3. The method of claim 2 , wherein the first air blower includes a plurality of first nozzles disposed below the first air blower and arranged along the first direction,
the second air blower includes a plurality of second nozzles disposed below the second air blower and arranged along the second direction, and
the air injected toward the target substrate is injected through the first nozzle and the second nozzle.

4. The method of claim 3 , wherein the air injected from the first nozzle included in the first air blower disposed on one side in the second direction is injected toward a lower end portion of the inner cup on the other side in the second direction, and
the air injected from the first nozzle included in the first air blower disposed on the other side in the second direction is injected toward a lower end portion of the inner cup on one side in the second direction.

5. The method of claim 1 , wherein at least some portions of the air injected from the air blower cross each other in an inner space of the inner cup.

6. The method of claim 1 , wherein the air injected from the air blower forms an air flow toward an outside of the target substrate.
