Abstract:
In a method for manufacturing a polarizing film comprising a polarizer, a first transparent protective film provided on one surface of the polarizer with an adhesive layer interposed therebetween, and a second transparent protective film provided on another surface of the polarizer with an adhesive layer interposed therebetween, the adhesive layers are obtained by first using active energy rays to carry out irradiation by way of the first transparent protective film and then using the active energy rays to carry out irradiation by way of the second transparent protective film to cure the active energy ray-curable adhesive composition.
