Abstract: An object of the present invention is to provide a method for producing a cholesteric liquid crystal layer, which is capable of freely controlling a tilt angle of an arrangement direction of bright portion and dark portion derived from a cholesteric liquid crystalline phase with respect to a normal line of a main surface of the cholesteric liquid crystal layer; a cholesteric liquid crystal layer; an optically anisotropic body; and a reflective film.
The method for producing a cholesteric liquid crystal layer according to the present invention includes a step X of forming a cholesteric liquid crystal layer A in which a liquid crystal compound is aligned into a state of a cholesteric liquid crystalline phase, satisfying all of the conditions 1 to 3, and a step Y of carrying out a treatment to increase or decrease a helical pitch of the cholesteric liquid crystalline phase in the cholesteric liquid crystal layer A obtained by the step X to increase or decrease a tilt angle of an arrangement direction of bright portion and dark portion derived from the cholesteric liquid crystalline phase, as observed in a cross-section perpendicular to a main surface of the cholesteric liquid crystal layer A, with respect to a normal direction of the main surface of the cholesteric liquid crystal layer A.
