RESIN FILM FOR POLARIZING PLATES, METHOD FOR PRODUCING SAID RESIN FILM, POLARIZING PLATE, AND DISPLAY DEVICE

WIPO Patent Application WO/2023/276310

A1

The present invention addresses the problem of providing: a resin film for polarizing plates that, when used in a polarizing plate in a display device, suppresses contrast deterioration and reductions in adhesive strength caused by the heat generated by semiconductor substrates; and a polarizing plate and display device comprising this resin film for polarizing plates.　The resin film for polarizing plates according to the present invention is a resin film for polarizing plates that is used in polarizing plates comprising at least an iodine-containing polarizer layer, wherein the resin film for polarizing plates characteristically comprises at least a thermoplastic resin and an iodine migration inhibitor and has a film thickness of at least 1 µm but less than 15 µm.
