Abstract:
1. A polyester film for display which comprises: a polyester film substrate containing an ultraviolet light absorber; and a coating layer formed on at least one surface of said polyester film substrate, said polyester film having a haze of not more than 2.0% and a light transmittance at 380 nm of not more than 5.0%, and which polyester film has ΔR of not more than 2.0%, said ΔR being defined by the formula: where Rs is an average value of absolute reflectance values as measured on a surface of the coating layer in a wavelength range of 2,400 to 2,000 nm; and Rc(min.) is a minimum value of absolute reflectance values as measured on a surface of the coating layer in a wavelength range of 300 to 800 nm.
