UNIAXIALLY STRETCHED MULTILAYER LAMINATED FILM, POLARIZING PLATE MADE OF THE SAME, OPTICAL MEMBER FOR LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a uniaxially stretched multilayer laminated film which has a small change in haze under a high temperature and excellent tear resistance and to provide a polarizing plate made of the same, an optical member for a liquid crystal display device and a liquid crystal display device.SOLUTION: There is provided a uniaxially stretched multilayer laminated film obtained by alternately laminating a first layer and a second layer, wherein the first layer comprises (i) 5 mol% or more and 50 mol% or less of a specific dicarboxylic acid component containing a naphthoic acid component and a dicarboxylic acid component having a phenylene group or a naphthalenediyl group as a dicarboxylic acid component and (ii) a polyester containing a diol component having an alkylene group having 2 to 10 carbon atoms as a diol component, the second layer is an optically isotropic layer which has an average refractive index of 1.50 or more and 1.60 or less and is composed of a copolymer polyester having a glass transition temperature of 90°C or more and a copolymerization amount of 5 mol% or more and 90 mol% or less, and the uniaxially stretched multilayer laminated film has an intrinsic viscosity of 0.55 dl/g or more and 0.75 dl/g or less.
