    • In a method of manufacturing a TFT substrate in accordance with an exemplary aspect of the present invention, an intrinsic semiconductor film, an impurity semiconductor film, and a conductive film for source lines are formed in succession, and a resist having a thin-film portion and a thick-film portions is formed on the conductive film for source lines. Then, etching is performed by using the resist as a mask, and after that, a part of the conductive film for source lines is exposed by removing the thin-film portion of the resist. Next, the exposed conductive film for source lines is etched by using the thick-film portions of the resist a mask, so that the impurity semiconductor film is exposed. Then, by etching the exposed impurity semiconductor film, a back channel region of a TFT 108 is formed. Further, a dummy back channel region 18a, which is irrelevant to the operation of the finished product, is also formed in a portion other than the TFT 108 region.

    • An automatic winding mechanism which includes a rotatable winding shaft, a first guide including a circular first guide portion and a second guide including a substantially U-shaped second guide portion is disclosed. A leader portion of a continuous sheet fed by a pair of feed rollers is introduced along a circumferential surface of the winding shaft by the first and second guide portions which are disposed so as to enclose the winding shaft in cooperation with each other. The continuous sheet is then automatically wound on the winding shaft since the circumferential velocity of the winding shaft is set higher than the feeding speed of the feed rollers. The winding mechanism also includes a first sensor for sensing whether the winding shaft is in place. The winding mechanism is started if the winding shaft is sensed and the winding mechanism is prevented from starting if the winding shaft is not sensed. A second sensor for sensing that a leader portion of the continuous sheet is disposed between the feed rollers and the winding shaft is also provided. When the second sensor is provided, tapered flanges are formed on both ends of the winding shaft and are tapered toward its center. A nip of the sheet by the feed rollers is cancelled by a nip cancelling mechanism when a leader portion of the continuous sheet is sensed by the second sensor. As a result, the leader portion is permitted to move freely to a proper centered position on the winding shaft.
