Abstract
There are provided a thin film polarizer having superior optical properties and a method of manufacturing the same. The thin film polarizer includes: forming a film laminate by attaching a non-stretched polyvinyl alcohol (PVA)-based film to at least one surface of a thermoplastic polyurethane film, using attractive force therebetween or using an adhesive; stretching the film laminate at a temperature of 45° C. to 55° C.; and separating the PVA-based film from the thermoplastic polyurethane film.
