Abstract
The method of manufacturing a light control element of the present invention includes: removing, in a predetermined portion of a light control film including a first base material with a transparent electrode layer and a second base material with a transparent electrode layer arranged so that transparent electrode layers are opposed to each other, and a liquid crystal light control layer sandwiched between the base materials with transparent electrode layers, one of the base materials with transparent electrode layers; swelling the liquid crystal light control layer remaining in the predetermined portion after the removal of the one of the base materials with transparent electrode layers with an organic solvent; bonding a pressure-sensitive adhesive tape to a surface of the swollen liquid crystal light control layer; and peeling off the pressure-sensitive adhesive tape from the light control film together with the swollen liquid crystal light control layer.
