A light control film 10 which is obtained by sandwiching a liquid crystal layer 14 between first and second laminates 13, 12 that are provided with at least alignment layers 23A, 23B, and which controls light transmitted therethrough by controlling the alignment of liquid crystal molecules 14A in the liquid crystal layer 14 by driving electrodes 22B, 22A that are provided on the first and second laminates 13, 12. With respect to the first laminate 13, a base 21B that is formed of a transparent film material is provided with a spacer 24 that maintains the thickness of the liquid crystal layer 14. With respect to the first and second laminates 13, 12, the Vickers hardness Xs of the spacer 24 is from 16.9 to 40.2 (inclusive), and the Vickers hardness Xf of a part of the second laminate 12, said part being in contact with the front end of the spacer 24, is from 11.8 to 35.9 (inclusive).
