Title: LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
According to the present invention, a polarizer protective film is obtained by laminating an antireflection layer and/or a low reflective layer on at least one surface of a polyester film, wherein: the polyester film has a retardation of 1500-30000 nm; and, in the polyester film having the antireflection layer and/or the low reflective layer laminated thereon, a reflectance spectrum, which is measured from the side on which the antireflection layer and/or the low reflective layer are laminated, has a bottom wavelength in a wavelength region of 600-780 nm , and a reflectance at the bottom wavelength is 2% or less.
