Abstract
A three-dimensional (3D) image display apparatus includes a directional backlight unit and a display panel. The 3D image display apparatus may include an absorptive wire grid polarizer in the directional backlight unit or the display panel, for minimizing a distance between a diffraction device of the directional backlight unit and a pixel of the display panel.
