PROBLEM TO BE SOLVED: To provide a thin film and high transparent laminate biaxially oriented polyester film without bleeding out during film production and interference band accompanied by ripples during mounted on a liquid crystal image display device.SOLUTION: There is provided a laminate biaxially oriented polyester film by laminating 50 or more layers of layers consisting of crystalline polyester (A layer) and layers different from the same and consisting of a thermoplastic resin (B layer) alternatively, where an outermost surface layer is the A layer with layer thickness of 5 μm to 50 nm, there are 10 or more layers having layer thickness of 50 nm or less consecutively from the second layer and an ultraviolet absorber is contained in the A layer or the B layer or both layers, and having light transmittance at wavelength of 400 nm, Tof 80% or more.SELECTED DRAWING: None |
