Abstract
An image display apparatus includes a backlight unit where a reflection panel is installed at a bottom thereof, a polarization panel which transmits only light of a particular polarization direction of light emitted from the backlight unit, a polarization switch which changes the polarization direction of incident light, a birefringent element array which is formed by alternately arranging a plurality of first and second birefringent elements and changes the polarization direction of incident light to make the polarization directions of light passing through the first and second birefringent elements perpendicular to each other, a reflective polarizer panel which transmits only light of a particular polarization direction of the light passing through the birefringent element array and reflects light of the other polarization direction, a lens array which separates incident light into a first view zone and a second view zone, and a display panel which displays an image.
