Abstract
A polarizing film may be manufactured without using adhesives by a method in which a protective film (B) is laminated onto at least one face of a polarizer (A), then adhered by thermocompression bonding. Thus problems on manufacturing method of a polarizing film possibly caused by use of adhesives will not be generated.
