LIQUID CRYSTAL OPTICAL SHUTTER

摘要: PROBLEM TO BE SOLVED: To obtain a liquid crystal optical shutter which may be driven by low voltage with electric power consumption and has excellent characteristics high-speed responsiveness specifying the product of thickness homogeneously oriented layer having positive dielectric anisotropy double refractive index to specific range. SOLUTION: The nearly aligned 1 is specified 180 400nm. In addition, angle that polarization axes or absorption pair polarizing plates 4 holding formed axis molecules surface adjacent plate are so set as attain 30 60 deg.. 0.12 thereof 27μm. 240nm. held two substrates 2 inside surfaces respectively subjected rubbing in opposite directions aligned. impressed on element transparent electrodes 3. Further, 45 deg. 1.
