Abstract: A flexible substrate separating device is provided to separate a flexible substrate using a thin thread. A flexible substrate separating device comprises a horizontal unit, a supporting substrate contacting unit, a pulley and its fixture, a solvent applying unit and a wheel. The horizontal unit(203) is connected to the one end of a handle(201) and a supporting substrate in a parallel. The supporting substrate contacting unit(205) is branched into two portions at the other end of the horizontal unit. The distance of the branched portions is farther than the horizontal length of the flexible substrate adhering to the top of the supporting substrate. The end parts of the branched portions are connected to each other by a thin thread. The pulley(211) and its fixture(209) are formed on a bobbin(207), the horizontal unit and supporting substrate contacting unit in order to induce the thin thread drawn from the bobbin to the end part of the supporting substrate contacting unit.

A buffer insulating layer(120) is formed on a plastic substrate(110). A silicon layer is formed on the buffer insulating layer, and then the silicon layer is patterned to form an active layer(130). A gate insulating layer is formed on the active layer, and then plural gate metal layers(150) are deposited on the gate insulating layer. The plural gate metal layers are patterned, and then a corner area of the lowermost gate metal layer formed on the gate insulating is etched.
