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.

Abstract: A light control member exhibits strong adhesion between an alignment layer and a bead spacer and includes: a first and second laminate with a substrate and an alignment layer, and which is arranged so that the alignment layer thereof faces the alignment layer of the first laminate; a liquid crystal layer between the first laminate and the second laminate, and the alignment is controlled by driving electrodes on at least one of the first laminate and the second laminate; and a plurality of bead spacers which are arranged within the liquid crystal layer. This light control member is also characterized in that: at least one of the alignment layer of the first laminate and the alignment layer of the second laminate has a plurality of projections that protrude toward the liquid crystal layer; and at least some of the bead spacers are held by the projections.
