Light control film, laminated glass and method for producing light control film
The reliability of a spacer is improved in comparison to conventional ones. A light control film which is obtained by sandwiching a liquid crystal layer between first and second laminates that are provided with at least alignment layers and which controls light transmitted therethrough by controlling the alignment of liquid crystal molecules in the liquid crystal layer by driving electrodes that are provided on the first and second laminates. With respect to the first laminate, a base that is formed of a transparent film material is provided with a spacer that maintains the thickness of the liquid crystal layer. With respect to the first and second laminates, the Vickers hardness of the spacer is from 16.9 to 40.2 inclusive, and the Vickers hardness of a part of the second laminate, the part being in contact with the front end of the spacer, is from 11.8 to 35.9 inclusive.
