Patent ID: 8884946

Claim:
An image display device, comprising: a display panel in which units of display including at least a pixel displaying a first observing point image and a pixel displaying a second observing point image are arranged in a matrix; and an optical distributer for distributing light emitted from said pixel displaying the first observing point image and pixel displaying the second observing point image in directions different from each other in a first direction, wherein said pixel displaying the first observing point image and pixel displaying the second observing point image are adjacent to each other in said first direction; said units of display are arranged in rows extending in said first direction and in columns extending in a second direction perpendicular to said first direction; a shielding unit is provided around an aperture of said pixel displaying the first observing point image and an aperture of said pixel displaying the second observing point image; the aperture of said pixel displaying the first observing point image and aperture of said pixel displaying the second observing point image include a first region where the apertures overlap with each other in said second direction and a second region that is a remaining region; a total aperture width in said second direction of the aperture of said pixel displaying the first observing point image and aperture of said pixel displaying the second observing point image in said first region is a first aperture width; an aperture width in said second direction of the aperture of said pixel displaying the first observing point image and aperture of said pixel displaying the second observing point image in said second region is a second aperture width; a third region where two of said units of display adjacent to each other in said first direction overlap with each other in said second direction is provided, and a total aperture width in said second direction of said two units of display in said third region is a third aperture width; the aperture of said pixel displaying the first observing point image and aperture of said pixel displaying the second observing point image each comprises a shape that is at least point-symmetric and not line-symmetric; centers of the apertures are shifted in said second direction with respect to a line parallel to said first direction and passing through a center of said units of display, and the aperture of said pixel displaying the first observing point image and aperture of said pixel displaying the second observing point image are point-symmetric about the center of said units of display; and said third aperture width is different from said first aperture width.
