Title:
Reflective polarizing film for liquid crystal display polarizing plate, polarizing plate for liquid crystal display composed of it, optical member for liquid crystal display and liquid crystal display
Document Type and Number:
Japanese Patent JP6329248
Kind Code:
B2
Abstract:
A reflective polarizing film for a liquid crystal display polarizer that, while being a reflective polarizer composed of a polymer film having a multi-layer structure, has a high polarization performance and additionally 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. Namely, 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 the reflective polarizing film has the 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.
