Detachment Apparatus Having Arched Drum Pad and Method for Fabricating Lightweight, Thin Liquid Crystal Display Device Using the Same

A method for fabricating a liquid crystal display (LCD) device, the method comprising:

• providing a first auxiliary substrate and a second auxiliary substrate, and a first thin mother substrate and a second thin mother substrate;
• attaching the first and second auxiliary substrates to the first and second thin mother substrates, respectively;
• performing an array process on the first mother substrate with the first auxiliary substrates attached thereto;
• performing a color filter process on the second mother substrate with the second auxiliary substrate attached thereto;
• attaching the array process-finished first mother substrate and the color filter process-finished second mother substrate;
• providing a detachment apparatus including an arched drum pad having O-rings formed on a lower surface thereof and a plurality of vacuum compartments formed on the lower surface and demarcated by the O-rings;
• loading the attached first and second mother substrates onto a table of the detachment apparatus;
• separating the second auxiliary substrate from the second mother substrate by using the arched drum pad;
• reversing the first and second mother substrates without the second auxiliary substrate and loading the first and second mother substrates onto the table;
• and
• separating the first auxiliary substrate from the first mother substrate by using the arched drum pad.
