A stereoscopic display device includes a display panel performing image display, and a lens array element including a first electrode, a second electrode opposed to the first electrode, and a liquid crystal layer disposed between the first electrode and the second electrode, the lens array element being configured in such a manner that a lens effect on display image light from the display panel is controlled depending on a voltage applied to the first electrode and a voltage applied to the second electrode. One of the first electrode and the second electrode is structured to allow an electric field to be applied to the liquid crystal layer for each of a plurality of predetermined sub-regions, individually.
