Optical laminate having antireflection film and light shielding film

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<R(λ1a,θ1a)/R(λ1b,θ1b)<1.5;  (i) Y(θ2)≤3%; and  (ii) Y(θ3)≤10%;  (iii) in which R (λ, θ) designates reflectance when light of a wavelength of λ nm is incident at an angle of θ, provided that λ1a=380 nm, θ1a=60° and λ1b=650 nm, θ1b=60°; and Y (θ) designates luminous reflectance at an incident angle of θ, provided that θ2=5° and θ3=60°.
