Abstract
Moiré generated in an autostereoscopic display utilizing a parallax barrier method is cancelled. The interval between visible light transmitting sections that are abutting in the horizontal direction of a parallax barrier is determined using: the average number of subpixels constituting one pixel for three-dimensional display in one row in the horizontal direction; the width of a subpixel, which forms a display; the distance from a predetermined diagonal moiré canceling position to the parallax barrier; the number of viewpoints of a video image used for displaying an autostereoscopic video image; and the distance (Z) from the image display surface of the display to the parallax barrier.
