    Abstract: Provided is an optical film that can suppress rainbow unevenness when viewed with the naked eyes without increasing the in-plane phase difference. The optical film has a low-refractive index layer on a plastic film, the plastic film is a biaxially stretched plastic film with an in-plane phase difference of 2500 nm or less, the low-refractive index layer is located on the outermost surface, and the optical film has a region in which ΔEab satisfies specific conditions, wherein the ΔEab is calculated from the differences between the L* value, the a* value, and the b* value obtained by measuring a laminate 1 including the optical film, the polarizer, and the surface light source under specific conditions and the L* value, the a* value, and the b* value obtained by measuring a laminate 2 including the polarizer and the surface light source under specific conditions, respectively.
