Abstract:
A cellulose acylate film comprising: (A) at least one retardation regulator that has an absorbance, in terms of a 1.0 g/liter solution, of 0.1 or less for a 1 cm path length within a wavelength region of 450 nm or greater but not greater than 800 nm; and (B) at least one near infrared absorber that has at least one maximum absorption wavelength at 700 nm or greater but not greater than 1200 nm and has an absorbance, in terms of a 1.0 g/liter solution, of 30.0 or less for a 1 cm path length within a wavelength region of 450 nm or greater but not greater than 650 nm.
