ABSTRACT:
A virtual stereographic display system which includes a display image surface, a polarizer disposed before the display image surface, a liquid crystal cell in which ferroelectric smectic liquid crystal is aligned, and disposed before the polarizer, a driving circuit connected to the liquid crystal cell so as to apply AC voltage synchronized with the frame signal of the image on the display image surface to the liquid crystal cell and to switch over the, polarization axes of the display light proceeding from the display image surface through the polarizer and liquid crystal cell by time division, and polarizing glasses having different polarization axes for the left eye and right eye for viewing the display light.
