Claim:
1. A stereoscopic display device comprising: a display panel that displays an image; a switch liquid crystal panel disposed to overlie the display panel and including a liquid crystal layer; a position sensor that obtains positional information about a viewer; and a control unit that receives the positional information from the position sensor and locally applies to the liquid crystal layer a first voltage for rendering the switch liquid crystal panel translucent and a second voltage for rendering the switch liquid crystal panel non-translucent to display a parallax barrier that depends on the positional information, wherein the control unit includes a timing adjustment unit that delays a time point for switching from the lower one of the first voltage and the second voltage to the higher one relative to a time point for switching from the higher one to the lower one by a delay time that depends on the positional information.
