THIN POLARIZING FILM, OPTICAL LAMINATE HAVING THIN POLARIZING FILM, AND METHOD OF PRODUCING THIN POLARIZING FILM

摘要

PROBLEM TO BE SOLVED: To provide a thin polarizing film having a small environmental load and excellent optical characteristics.SOLUTION: A thin polarizing film comprises a polyvinyl alcohol resin film in which iodine is adsorbed and oriented, and has a thickness of 10 μm or less, a single transmittance of 42.0% or more, a polarization degree of 99.95% or more, and an iodine content measured by ion chromatography of 17.6 g/(400 mm×700 mm sq.) or less.
