Beschreibung
Zusammenfassung:	The present invention relates to an optical film (9) provided with an optical layered body (1) in which two or more light-reflecting layers having mutually different central reflection wavelengths are layered, and a polarizer layer (8). The two or more light-reflecting layers are selected from: at least one light-reflecting layer RPRL (2, 3, 4) having a central wavelength of selective reflection in the range of 400 nm to 850 nm, in which a cholesteric liquid crystal phase which has a right-handed helical structure and has ability to reflect right circularly polarized light is fixed; and at least one light-reflecting layer LPRL (2, 3, 4) having a central wavelength of selective reflection in the range of 400 nm to 900 nm, in which a cholesteric liquid crystal phase which has a left-handed helical structure and has ability to reflect left circularly polarized light is fixed. In the light-reflecting layer RPRL and the light-reflecting layer LPRL (2, 3, 4), the central wavelengths of selective reflection of two m
