POLARIZING THIN FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

There is provided a polarizing film (10) which comprises a polyvinyl alcohol-based resin layer (12) including dichroic materials (11). The polarizing film (10) has (a) a film thickness t of 0.5 µm to 5 µm, and (b) an absorbance (absorbance per unit) of 1.5 or higher for extraordinary light per film thickness of 1 µm relative to monochromatic light having a wavelength of 550 nm.
