The present invention is to enable avoidance of a reduction in external appearance quality, and stable driving, and prevent diffracted light from being discerned by avoiding a reduction in transmittance and a deterioration in liquid crystal alignment. A light control film is provided with: a first laminate in which an alignment layer is provided; a second laminate in which an alignment layer is provided; a liquid crystal layer which is sandwiched between the first and second laminates and contains liquid crystal molecules; a spacer disposed in the liquid crystal layer to hold the thickness of the liquid crystal layer; and electrodes provided in the first laminate and/or the second laminate, and controls transmitted light by controlling the alignment of the liquid crystal molecules driven by the electrodes. The proportion of an area occupied by the spacer per unit area in a light controllable-region of the liquid crystal layer is 0.1-10%.
