Claim 9:
10. The liquid crystal film according to claim 9,
wherein an uneven distribution degree obtained by the following uneven distribution degree calculation method 3 is 3.5 or more,
uneven distribution degree calculation method 3: in a case where, among two main surfaces of the liquid crystal film, the main surface on the side where the leveling agent is unevenly distributed is denoted as a main surface A, and the other main surface is denoted as a main surface B, a secondary ion intensity derived from the photo-alignment compound in the liquid crystal film is measured by time-of-flight secondary ion mass spectrometry while emitting an ion beam from the main surface A toward the side of the main surface B of the liquid crystal film, and a region from the main surface A of the liquid crystal film to a depth position equivalent to 80% of a total thickness of the liquid crystal film toward the side of the main surface B is denoted as an upper layer region, and a region from the depth position to the main surface B of the liquid crystal film is denoted as a lower layer region, a ratio of a maximum value To of a secondary ion intensity derived from the photo-alignment compound in the lower layer region to an average value Ic2 of a secondary ion intensity derived from the photo-alignment compound in the upper layer region is denoted as an uneven distribution degree.
