Abstract: A cassette for a liquid crystal display (LCD) device, comprises: a body for receiving a substrate on which a plurality of LC panels divided from one another by a dummy region are formed; a plurality of supporting bars rotatably installed in the body and having a predetermined shape, for supporting a substrate; and a plurality of pads formed on each surface of the supporting bar with a different gap therebetween and contacting the dummy region of the substrate. When LCD devices of various sizes are received in the cassette, supporting bars for supporting each of the LCD devices are prevented from contacting an image display region of the LCD device and thus an inferiority of the LCD device is prevented.

Abstract: A substrate bonding apparatus for fabricating an LCD device aligns upper and lower stages to accurately bond first and second substrates. The distance to which the upper and lower substrates are spaced apart from each other during bonding is adjustable depending on the determined thickness of the first and second substrates. Further, sealant material disposed on a substrate may be prevented from becoming contaminated by foreign material.

Abstract: A device for fabricating LCD devices includes a base frame, a lower chamber unit on the base frame, an upper chamber unit over the lower chamber unit and moveable over the base frame, chamber moving means for raising/lowering the upper chamber unit, stages within interior spaces of the upper and lower chamber units, wherein substrates are securable to each of the stages, and sealing means on at least one surface of the chamber units for sealing an interior space definable by joined upper and lower chamber units, the substrates being within the sealed interior space.
