<p><P>PROBLEM TO BE SOLVED: To suppress stress on a workpiece when a protective sheet is removed from the workpiece. <P>SOLUTION: The contour of a grid-like region 12 of a TFT (Thin Film Transistor) side polarizing plate 7 is irradiated with a laser beam, the TFT side polarizing plate 7 at the end of the grid-like region 12 is pulled and thereby removed from a glass substrate 1. Consequently, the TFT side polarizing plate 7 can be peeled off from the glass substrate 1 without exerting a mechanical stress on the glass substrate 1, and therefore the stress on the glass substrate can be suppressed when the TFT side polarizing plate 7 is removed from the glass substrate 1. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
