Abstract
A method of manufacturing a thin film polarizer includes forming a film laminate by allowing a non-oriented polyvinyl alcohol-based film to be bonded to and sandwiched between two or more non-oriented polymer films using attractive force or an adhesive layer, orienting the film laminate so that the polyvinyl alcohol-based film has a thickness of 10 μm or less, and separating the polymer films and the polyvinyl alcohol-based film of the oriented film laminate from each other.
