Summary: | Provided is an optical film which has high selective absorbability to short-wavelength visible light having wavelengths around 420 nm and hence a high blue-light cutting function and can impart better display characteristics when used for a display device. The optical film satisfies the following two formulae: (1) A(420) ≥ 1 and (2) A(450)/A(420) ≤ 0.3, wherein A(420) represents an absorbance of the optical film at a wavelength of 420 nm and A(450) represents an absorbance of the optical film at a wavelength of 450 nm. |
