Zusammenfassung:PROBLEM TO BE SOLVED: To securely mount plastic films on various displays whose direct low-cost reflection preventing processing is hard, by forming a reflection preventing film on one face of a film base material having a specified thickness formed of a resin which contains a polyethylene terephthalate as a main component and forming an easy-to-adhere layer having a specified thickness on the other face. SOLUTION: On one face of a film base material formed of a resin having a polyethylene terephthalate with a thickness of 50-250μm as a main component, a reflection preventing film is formed. On the other face, an easy-to-adhere layer having a thickness of 0.1-2μm is formed. Here, when the thickness of the film base material is less than 50μm, there is a drawback in mechanical and formative stability. When the thickness exceeds 250μm, mounting property on displays deteriorate. When the thickness of the easy-to-adhere layer is less than 0.1μm, sufficient adhesion can not be obtained. Also, when it is thick to a certain extent, the effect of the adhesion saturates so as to be meaningless. Thus, the film can be mounted securely on various displays whose direct low- cost reflection preventing processing is hard.
