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.

Abstract: There is provided a polarizer that can realize the multi-functionalization and high-functionalization of an electronic device, such as an image display apparatus. A polarizer 1 according to an embodiment of the present invention includes a resin film containing a dichromatic substance, wherein the polarizer has a low dichromatic substance concentration portion whose content of the dichromatic substance is relatively low in the resin film. The low dichromatic substance concentration portion 2 is brought into contact with an acidic solution. In one embodiment, the low dichromatic substance concentration portion corresponds to a camera portion of an image display apparatus on which the polarizer is mounted.
