1. A method for manufacturing a display device, the method comprising:
forming a cutting line in a protective film detachably coupled to a target substrate;
initially peeling a first part of the protective film from the target substrate, the first part of the protective film extending from a second part of the protective film that is detachably coupled to the target substrate;
providing the initially peeled first part of the protective film to both a first peeler disposed on a first side of the target substrate and a second peeler disposed on a second side of the target substrate that opposes the first side of the target substrate in a first direction;
gripping a first corner portion of the initially peeled first part of the protective film with the first peeler and a second corner portion of the initially peeled first part of the protective film with the second peeler; and
translating both the first peeler having a grip on the first corner portion and the second peeler having a grip on the second corner portion in a second direction transverse to the first direction while rotating a portion of the first peeler about a first axis of rotation extending in the first direction and a portion of the second peeler about a second axis of rotation extending in the first direction to peel off the second portion of the protective film from the target substrate with respect to the cutting line.
