Patent number: 7968882Abstract: A flexible display device adapted to prevent a disconnection of pad electrode and a line short-circuit is disclosed. The flexible display device and the manufacturing method thereof according to the present embodiments forms only the barrier film or no layer on the mother substrate in the vicinity of the cut line which divides the mother substrate into the TFT substrate. Even when the mother substrate is pressed using a press machine, cracks or lifts of layers are not generated in the TFT substrate unlike the conventional technology so that a disconnection is not generated in the gate pad electrode or the data pad electrode. Thus, line short-circuits generated as the layers are separated and attached to the TFT substrate can be prevented.Type: GrantFiled: October 3, 2008Date of Patent: June 28, 2011Assignee: LG Display Co., Ltd.Inventors: Jae Gu Lee, Seung Chul Kang
