Abstract

The present invention relates to a method for manufacturing a thin polarizer, the method including: a step of preparing an unstretched polyvinyl alcohol-based film having a thickness of 20 μm or less, in which a strength applied to stretch the film by 6 times is 4 N or more; and a single stretching step of forming a stretched polyvinyl alcohol-based film having a thickness of 10 μm or less by stretching the unstretched polyvinyl alcohol-based film solely, and a thin polarizer manufactured by using the same.
