    摘要： A photoresist layer supporting film is (A) formed from a polymer composition comprising (i) 55 to 100% by weight of a copolyester containing ethylene terephthalate units as a main recurring unit and having a melting point of 210 to 250.degree. C. and (ii) 0 to 45% by weight of polybutylene terephthalate or a copolyester containing butylene terephthalate units as a main recurring unit and having a melting point of not lower than 180.degree. C. and (B) has a plane orientation coefficient of 0.08 to 0.16. Since this supporting film is excellent in substrate shape follow-up properties and resolution, it is suitable for the preparation of a photoresist film laminate by laminating a protective film and a photoresist layer on the surface thereof.

    摘要： A multilayered reflective polarizing film is provided that has high polarization performance comparable to that of an absorption-type polarizing plate, and is preferred as a polarizing plate attached to a liquid crystal cell. An optical member for liquid crystal display devices, and a liquid crystal display device formed from such a multilayered reflective polarizing film are also provided. Specifically, the reflective polarizing film includes a uniaxially stretched multilayered film in which a specific aromatic polyester containing (alkylenedioxy)di-2-naphthoic acid as a part of dicarboxylic acid components is used as a first layer, and an optically isotropic polyester having an average refractive index of 1.50 to 1.60 is used as a second layer, and that has a predetermined refractive index difference between the layers. The reflective polarizing film has an angle of orientation of 2 degrees or less.
