To provide a dimming device in which the area of an effective region (active area) is larger.SOLUTION: A dimming device includes a panel unit in which a plurality of dimming panels are stacked in a first direction. The dimming panel includes a first substrate, a second substrate that overlaps with the first substrate in a first direction, a first alignment film provided on the first substrate, a second alignment film provided on the second substrate and overlapping with the first alignment film in the first direction, a liquid crystal layer filling the space between the first alignment film and the second alignment film, a sealing material that is provided between the first substrate and the second substrate and outside the first alignment film and the second alignment film, and a conductive member that makes a first electrode provided on the first substrate and a second electrode provided on the second substrate electrically conductive. The conductive member is disposed inside the sealing material and outside the first alignment film and the second alignment film.SELECTED DRAWING: Figure 7 【課題】有効領域（アクティブエリア）の面積がより大きい調光装置を提供すること。【解決手段】調光装置は、複数の調光パネルが第１方向に積層されるパネルユニットを備える。調光パネルは、第１基板と、第１基板と第１方向で重なる第２基板と、第１基板に設けられる第１配向膜と、第２基板に設けられ且つ第１方向で第１配向膜と重なる第２配向膜と、第１配向膜と第２配向膜との間に充填される液晶層と、第１基板と第２基板との間であって且つ第１配向膜および第２配向膜よりも外側に設けられるシール材と、第１基板に設けられる第１電極と第２基板に設けられる第２電極とを導通させる導電部材と、を備える。導電部材は、シール材の内側且つ第１配向膜および第２配向膜の外側に位置する。【選択図】図７
