A method for manufacturing a light adjuster which can control an amount of light transmitted through it, the light adjuster comprising a pair of transparent substrates (103a, 103b) made of PET, transparent electrically conductive films (102a, 102b) made of ITO provided on respective facing surfaces of the pair of substrates (103a, 103b), and a liquid crystal layer interposed between the transparent electrically conductive films (102a, 102b), wherein the force required for stripping the liquid crystal layer from the transparent electrically conductive films (102a, 102b) is in the range of 15 to 50 g/cm, with the following steps: a) the substrates (103a, 103b), on one surface of each of which one of the transparent electrically conductive films (102a, 102b) is formed, are prepared; b) a polymer solution in the form of a paste mixed with nematic liquid crystal molecules is applied with a predetermined thickness onto a surface of one of the conductive films which is to be stuck; c) curing the applied polymer solution until it becomes sticky so as to form the liquid crystal layer having a predetermined consistency, wherein the predetermined consistency of the liquid crystal layer is determined such that the force required for stripping the liquid crystal layer off is in the range of 15 to 50 g/cm; d) the substrate with the other conductive film formed thereon is stuck onto the liquid crystal layer, so that the liquid crystal layer which has been cured to become sticky contacts the surface of the other conductive film which is to be stuck e) the light adjuster in the form of a long sheet is cut out in a size corresponding to the area required for its use, such as for a window or for a door; f) at a part of the periphery of the light adjuster, the liquid crystal layer, the other conductive film and the substrate on which it is formed, which are arranged to face the one conductive film, are stripped off to expose the surface of the one conductive film which had been stuck, and an electrode terminal section is placed on the surface of the exposed one conductive film of the light adjuster; g) similarly to step f), the surface of the other conductive film is exposed which had been stuck, and an electrode terminal section is placed on the surface of the exposed other conductive film which had been stuck. a) the substrates (103a, 103b), on one surface of each of which one of the transparent electrically conductive films (102a, 102b) is formed, are prepared; b) a polymer solution in the form of a paste mixed with nematic liquid crystal molecules is applied with a predetermined thickness onto a surface of one of the conductive films which is to be stuck; c) curing the applied polymer solution until it becomes sticky so as to form the liquid crystal layer having a predetermined consistency, wherein the predetermined consistency of the liquid crystal layer is determined such that the force required for stripping the liquid crystal layer off is in the range of 15 to 50 g/cm; d) the substrate with the other conductive film formed thereon is stuck onto the liquid crystal layer, so that the liquid crystal layer which has been cured to become sticky contacts the surface of the other conductive film which is to be stuck e) the light adjuster in the form of a long sheet is cut out in a size corresponding to the area required for its use, such as for a window or for a door; f) at a part of the periphery of the light adjuster, the liquid crystal layer, the other conductive film and the substrate on which it is formed, which are arranged to face the one conductive film, are stripped off to expose the surface of the one conductive film which had been stuck, and an electrode terminal section is placed on the surface of the exposed one conductive film of the light adjuster; g) similarly to step f), the surface of the other conductive film is exposed which had been stuck, and an electrode terminal section is placed on the surface of the exposed other conductive film which had been stuck.
