Abstract:
1. A stereoscopic display apparatus comprising: a backlight unit which emits light; a polarizer sheet which transmits only light with a predetermined polarization component among the light emitted from the backlight unit; a polarization switch which converts a polarization direction of incident light transmitted by polarization sheet; a birefringent element array comprising a plurality of alternating first and second birefringent elements which change the polarization direction of incident light transmitted by the polarization switch so that a polarization direction of light transmitted by the first birefringent elements is perpendicular to a polarization direction of light transmitted by the second birefringent elements; a lenticular lens sheet which separates and emits incident light transmitted by the birefringent element array to a first eye viewing zone and a second eye viewing zone; and a display panel which displays an image.
