    Abstract: A polarizing plate according to an embodiment of the present invention includes a laminate produced by laminating a resin substrate having a percentage of water absorption of 0.2% or more and 3.0% or less and a glass transition temperature of 60° C. or more on one side of a polyvinyl alcohol-based film having a thickness of 30 μm or less, the laminate being subjected to dyeing treatment and stretching treatment including at least in-boric-acid-solution stretching. The polyvinyl alcohol-based film serves as a polarizing film and the resin substrate serves as a protective film for 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.

    Abstract: As the polarizing fiber of the present invention, the cross sectional form perpendicular to the longitudinal direction has a sea-island structure, and the cross sectional form is continuously made up in the longitudinal direction. A resin (sea component) that constitutes the sea region of the sea-island structure comprises a dichroic dye, and a resin (island component) that constitutes the island regions of the sea-island structure is a transparent resin. The polarizing fiber of the present invention may be used as a forming material of a polarizer, for example. By using the above polarizing fiber, a polarizer wherein unevenness of the transmittance is small and cracks are less generated may be formed.
