ラ用液晶シヤツタ。 A pair of transparent substrates, each having a transparent electrode formed on opposing surfaces and an alignment treatment film formed on the electrode forming surface so that the orientation directions of liquid crystal molecules are substantially perpendicular to each other, are placed in a cell container in which two transparent substrates are bonded together via a frame-shaped sealing material. A nematic liquid crystal with positive dielectric anisotropy mixed with a color dye is filled, and the polarization axis direction is approximately the same as the liquid crystal molecule alignment direction of the alignment treatment film on one substrate surface of the cell container on both sides of the cell container. A liquid crystal shutter for a camera, characterized by having a pair of parallel or orthogonal polarizing plates arranged.
