摘要： A stripping device and method for stripping a plastic film from a glass substrate are provided. The stripping device includes a roller and a support member. The support member is disposed at a position where the plastic film is separated from the glass substrate. The support member supports and/or stretches the stripped plastic film. The roller is used to roll up the plastic film supported and/or stretched by the support member. Because the support member stretches and/or supports the plastic film as it is removed from the glass substrate, the plastic film is bent at a rounded angle. This reduces the stress generated in the plastic film during bending, thereby decreasing cracks in the plastic film and improving the overall useable yield of the plastic film.
