Abstract
A reflective polarizing film for a liquid crystal display polarizer that has a high polarization performance and eliminates a hue shift at an oblique azimuth of 45°, a polarizer for a liquid crystal display composed of the same, an optical member for a liquid crystal display, and a liquid crystal display are provided. In a reflective polarizing film for a liquid crystal display polarizer composed of a uniaxially stretched multi-layer laminate film in which a first layer and a second layer are alternately laminated, the reflective polarizing film has a polarization degree of 99.5% or more and an amplitude of a transmittance waveform of 2.0% or less in a wavelength range of 450 to 650 nm measured with respect to the polarized light incident at an incident angle of 60° on an incident plane including an azimuth angle of 45°, among polarized light components parallel to the transmission axis.
