Abstract

A bonding device for manufacturing a liquid crystal display device includes a bonding chamber for bonding first and second substrates and an ionizing device for introducing ionized gas or air into the bonding chamber.

Claims (42)

1. A method of bonding first and second substrates of a liquid crystal display device comprising:

opening a substrate feeding opening of the bonding chamber;

introducing first and second substrates into the bonding chamber through the substrate feeding opening;

closing the substrate feeding opening;

creating a vacuum within the bonding chamber after closing the substrate feeding opening;

bonding the first and second substrates together within the vacuum of the bonding chamber; and

introducing ions into the bonding chamber after creating the vacuum using an ion generator, wherein the ion generator is moved to the substrate feeding opening in the bonding chamber before introducing ions.

2. The method of claim 1 , wherein the ions are introduced into the bonding chamber through an ion opening in the bonding chamber.

3. A method of bonding first and second substrates of a liquid crystal display device comprising:

opening an opening of the bonding chamber;

introducing first and second substrates into the bonding chamber through the opening;

closing the opening;

creating a vacuum within the bonding chamber after closing the opening;

bonding the first and second substrates together within the vacuum of the bonding chamber; and

introducing ions into the bonding chamber,

wherein the ions are introduced into the bonding chamber through a vent pipe coupled to the bonding chamber for breaking the vacuum in the bonding chamber to place the bonding chamber at atmospheric pressure.

4. A method of bonding first and second substrates of a liquid crystal display device comprising:

opening a substrate introduction opening of the bonding chamber;

introducing first and second substrates into the bonding chamber through the substrate introduction opening;

closing the substrate introduction opening;

creating a vacuum within the bonding chamber after closing the substrate introduction opening;

bonding the first and second substrates together within the vacuum of the bonding chamber; and

introducing ions into the bonding chamber after creating the vacuum,

wherein the ions are generated at an interior wall surface of the bonding chamber adjacent a vent hole in the interior wall surface for breaking the vacuum in the bonding chamber to place the bonding chamber at atmospheric pressure.

5. The method of claim 1 , further comprising:

after the bonding, pressing the bonded first and second substrates together;

after pressing the first and second substrates together, opening the opening; and

removing the pressed, bonded first and second substrates through the opening.

6. A method of bonding first and second substrates of a liquid crystal display device comprising:

opening an opening of the bonding chamber;

introducing first and second substrates into the bonding chamber through the opening;

closing the opening;

creating a vacuum within the bonding chamber after closing the opening;

bonding the first and second substrates together within the vacuum of the bonding chamber; and

introducing ions into the bonding chamber after creating the vacuum;

after the bonding, pressing the bonded first and second substrates together; and

removing the pressed, bonded first and second substrates,

wherein the ions are introduced simultaneously with the pressing, and

wherein the ions are generated using a vent pipe coupled to the bonding chamber for breaking the vacuum in the bonding chamber to place the bonding chamber at atmospheric pressure, and wherein the vent pipe includes ion generating electrodes arranged along a length of the vent pipe that ionize a gas flowing through the vent pipe.

7. The method of claim 5 , wherein the ions are introduced after the pressing.

8. The method of claim 7 , wherein the ions are introduced before the removing.

9. The method of claim 7 , wherein the ions are introduced through the substrate feeding opening.
