Abstract

A stereoscopic display device is provided that enables stereoscopy for various viewing positions. A stereoscopic display device () includes: a display panel () configured to display images for a plurality of viewpoints, the images having parallax and being arranged regularly; a light beam convertor () disposed adjacent the front side of the display panel () configured to form virtual lenticular lenses by controlling a voltage, the lenticular lenses adapted to the images on the display panel () and being arranged at a certain interval; and a controller configured to control the display panel () and the light beam convertor (). The controller changes the focal length of the virtual lenticular lenses formed by the light beam convertor () depending on the distance between the display panel () and a viewer.
