POLARIZING DIFFUSION FILM, METHOD FOR PRODUCING POLARIZING DIFFUSION FILM, AND LIQUID CRYSTAL DISPLAY DEVICE COMPRISING POLARIZING DIFFUSION FILM

摘要

Disclosed are a film having polarization selectivity and diffusibility, and a means for easily producing the film.  The polarizing diffusion film is composed of substantially one kind of crystalline resin having an intrinsic birefringence of not less than 0.1, and has a total light transmittance to visible light of 50-90%, a transmission haze to visible light of 15-90% and a transmission polarization degree to visible light of 20-90%.
