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

摘要

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