| titleOfInvention | Polarizing film |
| abstract | (Problem) To provide a thin polarizing film with little leakage of blue light in a cross Nicol state. (Solution) A polarizing film having a thickness of 25 μm or less in which an iodine-based dye is adsorbed on a matrix containing PVA, and absorbance (A) at a wavelength of 480 nm in a cross Nicol state and absorbance at a wavelength of 700 nm ( The ratio (A/B) of B) is 1.42 or more, or the signal intensity (Int 310 ) and 210 cm -1 at 310 cm -1 in the central part in the thickness direction obtained by measuring the cross section of the polarizing film by Raman spectroscopy The ratio of the signal intensity (Int 210 ) at (Int 310 /Int 210 ) is L, and the copper ratio at the portion that has entered 10% of the thickness from one surface to the inside in the thickness direction is M, and the other A polarizing film in which 2 x L/(M+N) is 0.91 or less when the copper ratio in the portion which has entered 10% with respect to the thickness from the plane of the inside in the thickness direction is N (however, M ≤ N). |
