A method for cutting a liquid crystal display panel including: forming prearranged cut lines on a pair of attached mother substrates on which a plurality of panel regions have been disposed; and separating the liquid crystal display panel from a dummy glass around the liquid crystal display panel through a transfer unit which includes a body for adsorbing a liquid crystal display panel and transferring it, and a plate attached on an edge of the body, fixing and separating a dummy glass of a mother substrate from the liquid crystal display panel, and moving up and down separately from the body. A dummy removing plate is attached at an edge of a trans hand to remove a dummy glass when a breaking process-finished liquid crystal display panel is extracted, so a damage of the liquid crystal display panel due to the dummy glass can be prevented.
