Patent ID: 7116477

Claim:
A stereoscopic image display apparatus which displays a plurality of stereoscopic images including a first stereoscopic image and a second stereoscopic image different from the first stereoscopic image on an observation plane, the stereoscopic image display apparatus comprising: a display including, a plurality of first right eye pixels which display a first right eye image corresponding to the first stereoscopic image, a plurality of first left eye pixels which display a first left eye image corresponding to the first stereoscopic image and having parallax with respect to the first right eye image, a plurality of second right eye pixels which display a second right eye image corresponding to the second stereoscopic image, and a plurality of second left eye pixels which display a second left eye image corresponding to the second stereoscopic image and having parallax with respect to the second right eye image; a masking member; and a lenticular lens array which is provided between the display and the masking member and includes a plurality of lenses with optical power in the vertical direction, the lenses extending in the horizontal direction and arranged along vertical direction; wherein the first right eye pixels are adjacent to the first left eye pixels in the horizontal direction and are adjacent to the second right eye pixels in the vertical direction, and the second left eye pixels are adjacent to the second right eye pixels in the horizontal direction and are adjacent to the first left eye pixels in the vertical direction, and wherein, through the masking member and the lenticular lens array, the first right eye image and the second right eye image are displayed on different regions in a right eye observation region of the observation plane, and the first left eye image and the second left eye image are displayed on different regions in a left eye observation region of the observation plane, and wherein a region where image light from the first right eye pixels, the second right eye pixels, the first left eye pixels and the second left eye pixels do not reach exists between the right eye observation region and the left eye observation region, and wherein the masking member includes first and second parts with oblong shapes extending in the vertical direction, which are provided alternately in the horizontal direction, and wherein the first part includes a plurality of sub-parts provided in the vertical direction and respective sub-parts includes a plurality of apertures provided at different positions in the vertical and horizontal directions, and the light incident on the second part is shielded.
