A cholesteric liquid crystal film comprising:
- a cholesteric liquid crystal,
- wherein, in a cross section in a thickness direction observed with a microscope, the cholesteric liquid crystal film has a stripe pattern in which dark portions and bright portions are alternately arranged, and has a folded structure formed by the dark portions at a surface layer portion of one main surface of a pair of main surfaces which corresponds to a front surface and a back surface of the cholesteric liquid crystal film, and
- wherein the folded structure formed by the dark portions includes a structure in which two dark portions adjacent to each other are bonded to each other to look like a U shape.
