Abstract: An optical film includes a transparent substrate, one or more colored layers that contain a colorant and are provided on the transparent substrate, and one or more functional layers that are provided on a side opposite to that on which the transparent substrate is disposed, with the one or more colored layers interposed therebetween. The one or more colored layers contain a first color material in which a maximum absorption wavelength is in a range of 470 nm or more and 530 nm or less and a half-width of an absorption spectrum thereof is 15 nm or more and 45 nm or less, and a second color material in which a maximum absorption wavelength is in a range of 560 nm or more and 620 nm or less and a half-width of an absorption spectrum thereof is 15 nm or more and 55 nm or less.
