Abstract

A long polarizing film laminate capable of producing a polarizer that can achieve the multi-functionalization and high-functionalization of an electronic device, such as an image display apparatus, that shows no variation in quality when provided as a final product, and that is excellent in yield in its production. A polarizing film laminate according to an embodiment of the present invention includes: a long polarizer; and a surface protective film arranged on one surface side of the polarizer. The polarizing film laminate has, on the one surface side, exposed portions where the polarizer is exposed. The exposed portions are arranged in a lengthwise direction and/or a widthwise direction of the polarizer at predetermined intervals.
