Abstract:
1. An image display apparatus, comprising: a display panel having a plurality of display units which are arranged in a matrix and include at least a pixel displaying a first observing point image and a pixel displaying a second observing point image; and an optical means sorting lights emitted from said pixel displaying a first observing point image and pixel displaying a second observing point image in directions different from each other, wherein: said pixel displaying a first observing point image and pixel displaying a second observing point image are adjacent to each other in a first direction; said display units are arranged in rows extending in said first direction and in columns extending in a second direction perpendicular to said first direction; a shielding part is provided around the aperture of said pixel displaying a first observing point image and the aperture of said pixel displaying a second observing point image; the aperture of said pixel displaying a first observing point image and the aperture of said pixel displaying a second observing point image are composed of i) a first region where the aperture of said pixel displaying a first observing point image and the aperture of said pixel displaying a second observing point image overlap with each other in said second direction, and ii) a second region separate from said first region, the second region being a region where the aperture of said pixel displaying a first observing point image and the aperture of said pixel displaying a second observing point image do not overlap with each other in the second direction; the total aperture width in said second direction of the aperture of said pixel displaying a first observing point image and the aperture of said pixel displaying a second observing point image within said first region constitutes a first aperture width; the aperture width in said second direction of the aperture of said pixel displaying a first observing point image and the aperture of said pixel displaying a second observing point image within said second region constitutes a second aperture width; the derivatives of said first aperture width with respect to said first direction are real numbers other than zero provided that the direction from the boundary between said first and second regions toward the center of said first region is the positive direction of said first direction; and of the boundary line between said shielding part and the aperture of said pixel displaying a first observing point image and the boundary line between said shielding part and the aperture of said pixel displaying a second observing point image within said first region, the boundary line intersecting said second direction includes at least one or more flexion points.
