Abstract
Obtained is a configuration of a stereoscopic display device that allows a viewer to easily correct settings for stereoscopic display. A stereoscopic display device () includes: a display panel () for displaying an image; a switch liquid crystal panel () that is arranged so as to be stacked on the display panel (); a position sensor for acquiring position information of a viewer; and a control unit for causing the switch liquid crystal panel () to display a parallax barrier in which transmitting regions and non-transmitting regions are formed in periodic fashion in a predetermined alignment direction. The control unit has, as operation modes, at least a tracking mode in which, according to the position information, the parallax barrier is moved in the alignment direction and is displayed on the switch liquid crystal panel (), and a calibration mode for calibration of a reference position of the position information. The control unit sets a width of the transmitting region of the parallax barrier in the tracking mode, and a width of the transmitting region of the parallax barrier in the calibration mode, so that the widths are different from each other.
