Abstract:
The object of the present invention is to provide an optical laminate capable of reducing reflectance not only with respect to light incident vertically but also light incident obliquely, and further capable of obtaining a neutral reflected color tone even when light is incident obliquely. The optical laminate includes a base material, an antireflection film provided on one surface of the base material, and a light shielding film provided on the other surface of the base material. The optical laminate satisfies all of the following characteristics (i) to (iii): 0.5
