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.
