    • A multi-layer stretched film has 251 or more alternating layers which consist of first layers and second layers, wherein the first layers are made of a polyester which contains (i) 5 to 50 mol % of a naphthoic acid component as a dicarboxylic acid component and (ii) a diol having an alkylene group with 2 to 10 carbon atoms as a diol component; and the second layers are made of a thermoplastic resin having an average refractive index of 1.50 to 1.60 and differences in refractive index among a uniaxial stretching direction, a direction orthogonal to the uniaxial stretching direction and a film thickness direction of 0.05 or less before and after stretching, and the film has specific reflectance characteristics for a P polarization component and an S polarization component.
    • 多层拉伸膜具有由第一层和第二层组成的251个或更多个交替层,其中第一层由聚酯制成,该聚酯含有(i)5-50mol%的萘甲酸组分作为二羧酸组分 和(ii)具有碳原子数2〜10的亚烷基的二醇作为二醇成分; 并且第二层由平均折射率为1.50〜1.60的热塑性树脂和单轴拉伸方向,与单轴拉伸方向正交的方向和膜厚度方向的折射率的差异在前后均为0.05以下 并且该膜对于P偏振分量和S偏振分量具有特定的反射特性。
