A light adjuster which is free from occurrence of cloudiness, and can maintain sufficient workability to improve the yield. In the light adjuster, transparent electrically conductive films 102a and 102b are provided on respective surfaces of a pair of PET films 103a and 103b, a liquid crystal layer 101 is interposed between the transparent electrically conductive films 102a and 102b, and the force required for stripping the liquid crystal layer 101 from the transparent electrically conductive films 102a and 102b is in a range of 15 to 50 g/cm.
