The stereoscopic image display apparatus according to the present invention includes an image display unit in which pixel groups including pixels that display images corresponding to observation positions respectively are arranged cyclically; a lenticular array which substantially condenses light rays from the respective pixels at the predetermined observation positions and which is constituted by a plurality of horizontal lens lines arranged vertically, each of which is formed by a plurality of cylindrical lenses horizontally arranged at a predetermined cycle. And the apparatus includes a limiting member that limits light rays so that rays from a predetermined horizontal pixel lines may reach only the horizontal lens line having the same horizontal positions of cylindrical lenses.

A stereoscopic image display apparatus in accordance with the present invention solves a problem with a conventional multi-view stereoscopic image display apparatus in that the resolution of each parallax image deteriorates as the number of provided parallax images increases. The inventive stereoscopic image display apparatus forms a plurality of images for right and left eyes in observation regions for the observer's right and left eyes to enable the observer to obtain a stereoscopic view. At the same time, a region where no images are formed is provided between the right eye and left eye observation regions, because no actual observation is carried out in the region. This makes it possible to reduce the total number of parallax images without changing the number of actually observed parallax images, thus achieving a higher resolution of each parallax image actually observed.

Parallax images corresponding to a plurality of different view points are each divided into predetermined stripe images, a synthetic parallax image is synthesized from the stripe images, and display light, from stripe images corresponding to one view point of the synthetic parallax image on the image display element displaying the synthetic parallax image, is guided to a mask member having a mask pattern with predetermined openings and shields by a second optical system placed in front of the image display element. The display light passing through the openings of the mask member is condensed to a position corresponding to the view point on an observation surface a predetermined distance apart, by a first optical system, whereby an observer is permitted to stereoscopically observe image information displayed on the image display element.
