LIGHT CONTROL MEMBER
PROBLEM TO BE SOLVED: To provide a light control member in which degradation to an alignment film, a liquid crystal, and/or a dichroic dye and like hardly occurs.SOLUTION: A light control member 1 of the present invention comprises: a first transparent electrode 11; a second transparent electrode 16; a liquid crystal layer 8 which includes a liquid crystal material and a dichroic dye and in which the transmittance of light varies depending on an electric potential difference between the first transparent electrode 11 and the second transparent electrode 16; and transparent base materials 6, 15 which are arranged on at least one side of the liquid crystal layer 8 and absorb UV rays. According to the present invention, ultraviolet rays do not reach alignment films 17, 13 and the liquid crystal layer 8. Therefore, degradation of the alignment films 17, 13, the liquid crystal layer 8, and/or the dichroic dye are/is reduced.SELECTED DRAWING: Figure 1
【課題】配向膜、液晶及び／又は二色性色素等の劣化が生じにくい調光部材を提供する【解決手段】本発明の調光部材１は、第１透明電極１１と、第２透明電極１６と、液晶材料及び二色性色素を含み、前記第１透明電極１１と前記第２透明電極１６との間の電位差によって光の透過率が変動する液晶層８と、前記液晶層７の少なくとも一方の側に配置され、且つ紫外線を吸収する透明基材６，１５と、を含む。本発明によると、紫外線が配向膜１７，１３や液晶層８に到達しない。したがって、配向膜１７，１３、液晶層８及び／又は二色性色素の劣化が低減される。【選択図】図１
