Patent ID: 7583351

Claim:
A method for cutting a liquid crystal display panel comprising: transferring a pair of mother substrates on which a plurality of panel regions has been disposed to a scribing unit through a convey unit; forming first and second prearranged cut lines on front and rear surfaces of the mother substrates using a scribing unit; transferring the mother substrates with the first and second prearranged cut lines formed thereon to a breaking component through the convey unit; moving a transfer unit which includes a body having a plurality of suction members, a steam generator installed at an edge of the body and a pusher installed an outer side of the transfer unit to an upper side of the mother substrates; moving the transfer unit downward to be close to the surface of the mother substrates and spraying steam toward the first and second prearranged cut lines through the steam generators of the transfer unit; fixedly adsorbing the surface of the panel regions to be extracted through the adsorption members while the steam spraying through the steam generators are maintained for a certain pre-set time to further make cracks formed along the first and second prearranged cut lines; moving the transfer unit upward to separate liquid crystal display panels formed at the panel regions from a dummy glass therearound while spraying steam onto the surface of the mother substrates through the steam generator of the transfer unit; and transferring the liquid crystal display panels absorbed on the absorption members to a reversing unit with the separated dummy glass remaining on the convey unit.
