PROBLEM TO BE SOLVED: To provide a film, which is excellent in flexibility and causes double refraction to hardly develop, and a method for manufacturing the film. SOLUTION: A stretched film including amorphous thermoplastic resin under the state that the following conditions (i) and (ii) are simultaneously satisfied and the method for manufacturing the film are dealt. The condition (i) requires that the degree of in-plane orientation in polarized Raman spectrum measurement Dpl is≥0.3 and≤3.0. The condition (ii) requires that the degree of Z-direction orientation in the polarized Raman spectrum measurement Dth is≥0.1 and≤0.25 or≥4 and≤10. COPYRIGHT: (C)2010,JPO&INPIT |
