Abstract: A liquid crystal display device has a light source unit and a liquid crystal cell sandwiched by two polarizing plates. The light emitted by the light source unit has separated peaks in each of blue, green and red wavelength ranges. The green and red peaks have a full width at half maximum intensity of 20 nm or more. At least one of the polarizing plates has a polarizer and a protective film with a Re of 5,000 nm or more and low moisture permeability. The device exhibits excellent color reproducibility and prevents display nonuniformity under a high temperature and high humidity environment.

Abstract: A method for producing a polyester film includes: an unstretched film formation step of forming an unstretched polyester film having a thickness of from 2.5 mm to 5.0 mm by melt-extruding a polyester resin using an extruder, and cooling the polyester resin; and a stretching step of stretching the formed unstretched polyester film in at least one direction after heating the formed unstretched polyester film so as to have a mean temperature T1 (° C.), a surface temperature, and a central temperature. The mean temperature T1 (° C.) satisfies a relationship represented by formula (1): Tg−20° C.
