摘要：A multi-layer stretched film has 251 or more alternating layers which consist offirst layers and second layers, wherein the first layers are made of a polyester whichcontains (i) 5 to 50 mol % of a naphthoic acid component as a dicarboxylic acidcomponent 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 averagerefractive index of 1.50 to 1.60 and differences in refractive index among a uniaxialstretching direction, a direction orthogonal to the uniaxial stretching direction and a filmthickness direction of 0.05 or less before and after stretching, and the film has specificreflectance characteristics for a P polarization component and an S polarizationcomponent.
