Abstract
A method of peeling a mother protective film from a mother display panel includes: laminating the mother display panel and the mother protective film, the mother display panel including a plurality of display cells each including a display area and a peripheral area around the plurality of display cell; forming a target area and a dummy area in the mother protective film by forming a cutting line in a closed loop shape enclosing the target area corresponding to each of the display cells and a first additional cutting line in a first direction near the cutting line; physically peeling off the dummy area from the mother display panel, including: primarily peeling off a portion of the mother protective film adjacent to the first additional cutting line; and secondarily peeling off rest of the mother protective film from the mother display panel along the cutting line.
