Title: LIQUID CRYSTAL DISPLAY DEVICE, POLARIZING PLATE, AND POLARIZER PROTECTIVE FILM
Abstract:
The present invention addresses the problem of providing a liquid crystal display device, a polarizing plate, and a polarizer protective film, wherein the occurrence of rainbow spots can be suppressed even when the polarizer protective film is thinned, and the wavelength spectra of a backlight source is diversified by widening the color gamut of the liquid crystal display device. A polarizer protective film formed from a polyethylene terephthalate-based resin film, said polarizer protective film characterized in that the polyethylene terephthalate-based resin film satisfies the following (1) and (2): (1) the polyethylene terephthalate-based resin film has a retardation of 3,000-30,000 nm; and (2) the rigid amorphous fraction is at least 33 wt%.
