LIQUID CRYSTAL SHUTTER AND THREE-DIMENSIONAL LIQUID CRYSTAL DISPLAY SYSTEM

摘要

A liquid crystal layer (32) for a liquid crystal shutter (10) according to an embodiment of the present invention is a TN type liquid crystal layer that includes nematic liquid crystal material having positive dielectric anisotropy, and the nematic liquid crystal material has a chiral pitch of less than approximately four times the thickness of the liquid crystal layer. A circuit (40) is constituted such that a drive voltage is applied to a first electrode (14) and a second electrode (24) such that a first voltage (V_H) that puts the liquid crystal shutter (10) into a closed state, a second voltage (V₀) that puts the liquid crystal shutter (10) into an open state, and a third voltage (V_L) having an absolute value that is smaller than the absolute value of the first voltage (V_H) and larger than the absolute value of the second voltage (V₀) are applied to the liquid crystal layer (32). The voltages are supplied such that, the third voltage (V_L) is applied to the liquid crystal layer (32) after the first voltage (V_H) has been applied to the liquid crystal layer (32) and before the second voltage (V₀) is applied to the liquid crystal layer (32).
