Abstract: In a method for fabricating a lightweight and thin liquid crystal display (LCD), a first mother substrate, a subsidiary substrate and a thin second mother substrate are provided. An edge cut is formed by cutting edges of the first and second mother substrates and the subsidiary substrate to be inclined at a predetermined angle. An array process is performed on the first mother substrate. The subsidiary substrate is attached to the second mother substrate. A color filter process is performed on the second mother substrate having the subsidiary substrate attached thereto. The first and second mother substrates are attached together. The subsidiary substrate is separated from the first and second substrates by spraying air between the second mother substrate and the subsidiary substrate, in which the edge cut is formed.
