ABSTRACT:
A directional display device configured to display a plurality of directional images simultaneously is provided. The directional display device includes a liquid crystal panel having a liquid crystal layer and a light reflecting membrane arranged behind the liquid crystal layer. The liquid crystal panel is configured to form the plurality of images by using a plurality of pixel dots. The directional display device includes a barrier portion arranged in front of the liquid crystal panel. The barrier portion has a plurality of light shields and a plurality of apertures. Each of the apertures is arranged in such a way that one of the apertures is associated with n (an integer being no less than two) pixel dots if n images are displayed. Each of the light shields has behind thereof a luminescent layer for illuminating the liquid crystal panel.
