Abstract

An object is to provide a stereoscopic video display device having improved convenience which simultaneously displays a plurality of stereoscopic video footages on one screen, thereby allowing a viewer to simultaneously view the plurality of stereoscopic video footages. The stereoscopic video display device includes: a display panel 230 in which a screen for displaying a plurality of stereoscopic video footages is arranged; and a video control section 240 that controls the display of the plurality of stereoscopic video footages. Each stereoscopic video footage includes right-eye video and left-eye video each having parallax with respect to the other. The video control section 240 simultaneously displays the stereoscopic video footages in given positions on the screen, periodically displays the right-eye video and the left-eye video of each stereoscopic video footage, and synchronizes the timing at which the right-eye video and the left-eye video of each stereoscopic video footage are displayed.
