Abstract: The optical sheet includes: a first adhesive layer containing an adhesive and a colorant, the first adhesive layer having opposite first and second surfaces; and an ultraviolet shielding layer arranged to face the first surface. The colorant contains at least one of a first coloring material having a maximum absorption wavelength in a range of 470 to 530 nm and an absorption spectral half width of 15 to 45 nm, a second coloring material having a maximum absorption wavelength in a range of 560 to 620 nm and an absorption spectral half width of 15 to 55 nm, and a third coloring material in which a wavelength having the lowest transmittance in a wavelength range of 400 to 800 nm is in a range of 650 to 800 nm. The ultraviolet shielding layer has an ultraviolet shielding rate of 85% or more. ΔE * ab.

Abstract: An optical film comprises: a transparent substrate having an ultraviolet blocking rate of 85% or more according to JIS L 1925; one or more functional layers formed on a first surface side of the transparent substrate; and a colored layer that is formed on a second surface side of the transparent substrate that is configured by one or more layers containing a colored material. The colored layer contains a first colorant that has a maximum absorption wavelength in a range of 470 nm or more and 530 nm or less, an absorption spectrum thereof having a half-width of 15 nm or more and 45 nm or less, and a second colorant that has a maximum absorption wavelength in a range of 560 nm or more and 620 nm or less, an absorption spectrum thereof having a half-width of 15 nm or more and 55 nm or less.
