Abstract:
1. An apparatus for cutting a liquid crystal display panel, comprising: a table on which a mother substrate is loaded, wherein the table includes an impact absorption layer, a surface planarization layer, and an electrostatic preventing layer that are sequentially stacked on a base; a scribing unit for forming first scribing lines in a first direction and second scribing lines in a second direction for dividing LCD panels on the mother substrate where a plurality of LCD panels are formed; a flipping unit for flipping the mother substrate; and a breaking unit having a breaking bar for striking portions of the flipped mother substrate corresponding to the first scribing lines to form a first crack on the first scribing lines, and having a plurality of breaking rollers for pressing portions of the flipped mother substrate corresponding to the second scribing lines to form a second crack on the second scribing lines, wherein a pressure applying position of each breaking roller is individually adjustable in accordance with different sizes of the LCD panels on the mother substrate, wherein the portions of the flipped mother substrate struck by the breaking bar are different from the portions of the flipped mother substrate pressed by the breaking rollers, wherein each roller is independently movable vertically with respect to the mother substrate such that during a cutting operation, each individual roller moves up or down between pressure applying and non-pressure applying positions such that only the portions of the mother substrate with the second scribing lines are contacted by the rollers.
