    Abstract: A method of manufacturing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate including a resin substrate having a long shape and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate, to thereby produce a polarizing film on the resin substrate; laminating an optically functional film on a side of the polarizing film of the laminate, to thereby produce an optically functional film laminate; and cutting widthwise direction end portions of the optically functional film laminate. The cut portions include the resin substrate, the polarizing film, and the optically functional film.

    Abstract: A surface-protective film-attached polarizing film is disclosed which includes a polarizing film (A) having a thickness of 100 μm or less, and a surface-protective film (B) provided on at least one surface of the polarizing film (A), wherein the polarizing film (A) comprises a polarizer, and a protective film provided on at least one surface of the polarizer, the polarizer comprises a polyvinyl alcohol-based resin and has a thickness of 10 μm or less, the polarizing film (A) has a width WA, the surface-protective film (B) has a width WB, a difference between the widths WA and WB (WA−WB) is 3 mm or more, and a peel strength of the surface-protective film (B) to the polarizing film (A) is 0.2 N/25-mm or less. The surface-protective film-attached polarizing film allows to be restrained the polarizing film from being broken, when the surface-protective film is peeled from the polarizing film.

    Abstract: A method of manufacturing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate having a resin substrate and a polyvinyl alcohol-based resin layer formed on at least one side of the resin substrate to produce a polarizing film on the resin substrate; laminating an optically functional film on the laminate on a polarizing film side to produce an optically functional film laminate; and peeling the resin substrate from the optically functional film laminate. The peeling is performed so that an angle α formed between a surface of the optically functional film laminate immediately before the peeling and a peeling direction of the resin substrate is smaller than an angle β formed between the surface of the optically functional film laminate immediately before the peeling and a peeling direction of the polarizing film.
