    • PURPOSE:To enable low power driving of driving voltage and enable stable operation by using a PLZT sintered body that shows memorability at normal temperature and shows secondary effect at electrooptical shutter driving temperature. CONSTITUTION:An electrical shutter 3 is provided between linear polarizing plates 1, 2. Opposed electrodes 4, 5 are arranged in the PLZT ceramics sintered body of the shutter 3. Polarizing plates 1, 2 are so selected that direction of electric field vector of linearly polarized light selected by them intersect at right angle, and the direction of electric field of the sintered body 6, i.e. the direction of optic axis, is made about 45 deg.. When linearly polarized light advances in the shutter 3 after passing through the plate 1, the rotation of vector takes place depending on applied voltage of the shutter and the thickness of the plate, and the light passes through the plate 2 rotating 90 deg.. The shutter 3 shows memorability at normal temperature, and shows secondary effect at specified electrooptical shutter driving temperature. Thus, driving by low power becomes possible.
