It is an object of the invention to provide a peeling method which does not damage a peeling layer, and to perform peeling not only a peeling layer having a small-size area but also an entire peeling layer having a large-size area with a preferable yield. In the invention, after pasting a fixing substrate, a part of a glass substrate is removed by scribing or performing laser irradiation on the glass substrate which leads to providing a trigger. Then, peeling is performed with a preferable yield by performing peeling from the removed part. In addition, a crack is prevented by covering the entire face except for a connection portion of a terminal electrode (including a periphery region of the terminal electrode) with a resin.
