A process stably produces a light reflective film with plural light reflective layers formed of a fixed cholesteric liquid crystal phase, having high transparency and excellent light-reflective characteristics. The process of preparing a light reflective film having at least two light reflective layers formed of a fixed cholesteric liquid crystal phase includes first allowing a curable liquid crystal composition to form a cholesteric liquid crystal phase on a first light reflective layer formed of a fixed cholesteric liquid crystal phase, then carrying out a curing reaction of the curable liquid crystal composition under an irradiation of an ultraviolet light to fix the cholesteric liquid-crystal phase, thereby to form a second light reflective layer. In the second step, the ultraviolet light is irradiated to the curable liquid crystal composition through a member capable of lowering at least the intensity of the ultraviolet light with a wavelength of 340 nm or shorter. |
