A light reflection film includes at least one light reflection layer RPRL in which a cholesteric liquid crystal phase of a right-handed helical structure having right circularly polarized light reflection ability is fixed; and at least one light reflection layer LPRL in which a cholesteric liquid crystal phase of a left-handed helical structure having left circularly polarized light reflection ability is fixed. A total of three or more layers of the light reflection layer(s) RPRL and the light reflection layer(s) LPRL are laminated. The light reflection layer(s) RPRL and the light reflection layer(s) LPRL laminated each have a selective reflection center wavelength shifted by an interval of 10 nm or more and 160 nm or less between two light reflection layers adjacent to each other.
A light reflection film comprising:
