Substrate bonding apparatus for liquid crystal display device

A method of display device, comprising:

• providing unbonded first and second substrates;
• loading the unbonded first and second substrates through a first side of a bonding station;
• bonding the loaded first and second substrates within the bonding station;
• and
• unloading the bonded first and second substrates from the bonding station through a second side, different from the first side.

A method of manufacturing a liquid crystal display (LCD) device, comprising:

• preparing a first substrate and a second substrates;
• a first loading process including the steps of:
• moving a lifting system along a first direction to a first position;
• placing the first substrate on the lifting system;
• moving the lifting system along a second direction to a second position;
• and
• placing the first substrate on an upper surface of a lower stage, wherein the substrate is positioned over the lifting system before the lifting system is moved along the first direction;
• and
• a second loading process including the steps of:
• placing the second substrate on a lower surface of an upper stage, wherein the second loading process is performed before the first loading process;
• moving at least one of the upper stage along the second direction and the lower stage along the first direction;
• performing an alignment process to certify alignment of the first and second substrate;
• and
• bonding the first substrate and the second substrate together, wherein said moving includes extending the lifting system along the first direction to raise the bonded first and second substrates from the lower stage;
• and
• removing the bonded first and second substrate from the lifting system, and
• wherein the thickness of the bonded first and second substrates is substantially uniform over the entire surface area of the substrates.
