IMAGE DISPLAY DEVICE, INCLUDING A BLACK MATRIX, CAPABLE OF DISPLAYING IMAGES IN A PLURALITY OF VIEW POINTS FOR SUPPRESSING A PROBLEM ORIGINATING FROM A LIGHT BLOCKING PORTION ARRANGED IN A PIXEL APERTURE OR A STRUCTURAL OBJECT AND ACCOMPLISHING A HIGH APERTURE RATIO

An image display device includes a display element having a unit of display comprising sub pixels displaying images for first and second view points, and an optical unit that distributes light emitted from respective sub pixels into different first directions. When a region surrounded a black matrix in the sub pixel is defined as an aperture, the sub pixels form a base unit that is an adjoining pixel pair including two sub pixels arranged with a data line therebetween. When virtual lines evenly dividing a width of the sub pixel in the first direction into K+1 pieces are presumed, K number of storage capacitor lines are arranged across at least one virtual line in the aperture. In the adjoining pixel pair, the K number of storage capacitor lines of one sub pixel are nonparallel to the K number of storage capacitor lines of the other sub pixel.
