  • Patent number: 6582789
    Abstract: A surface protective film which can be used in the production of components associated with a liquid crystal display such as a polarizer to improve productivity and yields since no air bubbles are trapped when stuck to a substrate having unevenness in the surface and since the adhesion is low and a change of the adhesion with the passage of time is small and which can be highly transparent and improve inspectability by using a polyester film having little particles as a base material. It is treated by an antistatic agent or a release agent the surface of the surface protective film opposite to the surface in which the adhesive layer is formed, as a result, control of static electrification in case the surface protective film is peeled off and removal of the dust adhering to the surface can be made easy.
