摘要
PROBLEM TO BE SOLVED: To provide a uniaxially oriented multilayer laminate film and a reflective polarizing film for a polarizing plate of a liquid crystal display, the films which have polarizing performance and improved interlayer adhesiveness while they are polymer films having a multilayer structure using a polyethylene terephthalate polymer for a layer having a high refractive index characteristic, and to provide a polarizing plate for a liquid crystal display, which comprises the film, an optical member for a liquid crystal display, and a liquid crystal display.SOLUTION: The uniaxially oriented multilayer laminate film includes a first layer and a second layer alternately laminated and has such characteristics that: (1) the first layer contains polyester, containing ethylene naphthalate units by 50 mol% or more and 100 mol% or less based on repeating units constituting the polyester; and (2) a polymer constituting the second layer is a copolymer polyester having a 2,6-naphthalene dicarboxylic acid component, an ethylene glycol component, an alicyclic diol component, and a trimethylene glycol component as copolymer components.SELECTED DRAWING: None
