Abstract

The present invention relates to a method for manufacturing a single-faced thin polarizing plate, including: supplying a process film to one surface of a polarizer having a thickness of 50 μm or less; supplying a protection film to the other surface of the polarizer; forming an adhesive layer by supplying an adhesive composition between the polarizer and the protection film; pressing a laminate of the process film/the polarizer/the protection film by disposing a pair of pressing units on a surface of each of the process film and the protection film; and stripping the process film, in which stripping force between the polarizer and the process film is 1.0 N or less.
