  • Patent number: 11150521
    Abstract: 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.

  • Publication number: 20210208445
    Abstract: A method for manufacturing a laminated glass whereby, in a laminated glass comprising a liquid crystal film sandwiched therein and having a three-dimensionally curved surface shape, the formation of wrinkles in the liquid crystal film can be suppressed; and a laminated glass which has a three-dimensionally curved surface shape and in which wrinkles in a liquid crystal film sandwiched therein are suppressed. The method for manufacturing the laminated glass comprises: a heat molding step for heating the liquid crystal film to a temperature higher than the glass transition point of the first base material layer and the second base material layer; and a bonding step for, after completing the heat molding step, heating the laminate, wherein the liquid crystal film is sandwiched between the first glass sheet and the second glass sheet, at a temperature lower than the glass transition point and bonding the same by applying a preset pressure.
