An automatic-darkening filter10,10'that comprises a first polarizer14, a second polarizer18, a first liquid-crystal cell16, and a sensor64. The first polarizer14has a first polarization direction, and the second polarizer18has a second polarization direction. The liquid crystal cell16is disposed between the first and second polarizers14,18and contains first and second optically-transparent, flexible, glass layers40and42with the liquid crystal layer48being located between these layers. The sensor64detects incident light and causes a signal to be sent, which causes molecular rotation within the liquid crystal layer. The inventive automatic-darkening filter is beneficial in that overall product weight can be reduced and the view field can be increased.本發明提供一種自動暗化濾光片10、10'，其包含一第一偏光器14、一第二偏光器18、一第一液晶單元16及一感測器64。該第一偏光器14具有一第一偏光方向，且該第二偏光器18具有一第二偏光方向。該液晶單元16安置於該第一偏光器14與該第二偏光器18之間且含有第一及第二光學上透明可撓性玻璃層40及42，其中液晶層48位於此等層之間。該感測器64偵測入射光且造成發送一信號，該信號造成該液晶層內之分子旋轉。本發明之自動暗化濾光片係有益的，此係因為可減小總產品重量且可增加視場。
