POLARIZING FILM, OPTICAL FILM LAMINATE INCLUDING POLARIZING FILM, STRETCHED LAMINATE FOR USE IN PRODUCTION OF OPTICAL FILM LAMINATE INCLUDING POLARIZING FILM, PRODUCTION METHODS FOR THEM, AND ORGANIC EL DISPLAY DEVICE HAVING POLARIZING FILM

摘要

T 42.5; and P 99.5, wherein T is a single layer transmittance, and P is a polarization rate. The polarizing film for an organic EL display device may be prepared by subjecting a laminate comprising a non-crystallizable ester type thermoplastic resin substrate and the polyvinyl alcohol type resin layer formed on the substrate, to 2-stage stretching consisting of preliminary in-air stretching and in-boric-acid-solution stretching.
