Iodine polarizing film, method of producing the same, and polarizing plate comprising the same
摘要：
An iodine polarizing film includes a polymer film and iodine adsorbed and oriented on the polymer film, wherein an iodine content of the polarizing film is within the range of 1.9 to 3% by weight per 2.85 mm3, a single transmittance of the polarizing film is within the range of 43 to 45%, and a ratio (A2/A1) of a crossed absorbance A2 at a wavelength of 610 nm to a crossed absorbance Al at a wavelength of 480 nm is 1.16 or less.
