Could be aggravated and give an excessive feeling of fatigue.

An object of the present invention is to improve the above-mentioned problems of the conventional example and to spatially generate the solid body to obtain a more natural feeling of use.

[0008]

In order to solve the above problems and improve the usability of the stereoscopic display device, the surface for displaying an image is moved by a single pixel or a plurality of pixels in the direction perpendicular to the surface. Depth generation means is provided.

[0009]

[Operation] The depth of the displayed image is expressed by the depth generation means,
The focus of the user's eyes and the depth of the displayed image are approximated or proportional to the absolute or relative distance.
