Abstract

The present disclosure relates to an optical film including an optical laminate in which two or more light reflection layers having center wavelengths of reflection different from each other are laminated and a polarizing element layer. The two or more light reflection layers are selected from at least one light reflection layer RPRL having a center wavelength of selective reflection in the range of 400 nm or more and 900 nm or less, in which a cholesteric liquid crystal phase with a right-handed spiral structure having right-handed circularly polarized light reflectivity is fixed, and at least one light reflection layer LPRL having a center wavelength of selective reflection in the range of 400 nm or more and 900 nm or less, in which a cholesteric liquid crystal phase with a left-handed spiral structure having left-handed circularly polarized light reflectivity is fixed. Light reflection layer RPRL and light reflection layer LPRL each have a center wavelength of selective reflection shifted from that of a light reflection layer adjacent to each other by an interval of 40 nm or more and 500 nm or less, and the maximum reflectance of optical laminate is 50% or less.
