摘要： The present invention provides a method of producing a thin polarizing film having both excellent optical characteristics and excellent in-plane uniformity.The method of producing a thin polarizing film includes stretching a thermoplastic resin substrate in a first direction, followed by formation of a polyvinyl alcohol-based resin layer on the thermoplastic resin substrate to prepare a laminate and shrinking and stretching the laminate in the first direction and a second direction, respectively.
