A polarizing film comprising a polarizer (A) and a protection film (B) prepared on at least one face of the polarizer (A), wherein the protection film (B) is adhered to the polarizer (A) without using adhesives, is induced problems by use of adhesives.
摘要:
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.
