REFLECTIVE POLARIZING FILM FOR LIQUID-CRYSTAL-DISPLAY POLARIZER, LIQUID-CRYSTAL-DISPLAY POLARIZER COMPRISING SAME, LIQUID-CRYSTAL-DISPLAY OPTICAL ELEMENT, AND LIQUID-CRYSTAL DISPLAY

摘要

This invention provides the following: a reflective polarizing film for a liquid-crystal-display polarizer, said reflective polarizing film exhibiting no hue offset at a lateral angle of 45° and high polarization performance despite being a reflective polarizer comprising a polymer film with a multi-layered structure; a liquid-crystal-display polarizer comprising said reflective polarizing film; a liquid-crystal-display optical member; and a liquid-crystal display. This reflective polarizing film for a liquid-crystal-display polarizer comprises a uniaxially-stretched multi-layered laminated film in which first layers and second layers are laminated together in an alternating manner, wherein the polarization degree of said reflective polarizing film is greater than or equal to 99.5% and the amplitude, over the 450-650 nm wavelength range, of a transmittance waveform measured for a specific polarization component, namely the polarization component parallel to the transmission axis of the film, of polarized light incident at an angle of incidence of 60° in an incidence plane containing a lateral angle of 45° is less than or equal to 2.0%.
