Zusammenfassung:	A configuration of a stereoscopic display device that is capable of maintaining crosstalk at a low level even when a viewer moves is provided. A stereoscopic display device (1) includes: a display panel (10) for displaying an image; a switch liquid crystal panel (20) that is arranged so as to be stacked on the display panel (10); a position sensor for acquiring position information of a viewer; and a control unit for moving a parallax barrier in which transmitting regions and non-transmitting regions are formed in periodic fashion in a predetermined alignment direction, in such a manner that the parallax barrier is moved in the predetermined alignment direction in accordance with the position information, and causing the switch liquid crystal panel (20) to display the parallax barrier. The switch liquid crystal panel (20) includes: a liquid crystal layer (23) in which refractive index anisotropy Δn of liquid crystal molecules is 0.14 or less; a first substrate (21) and a second substrate (22) that face each other with the liquid crystal layer (23) being interposed therebetween; and an electrode group including a plurality of electrodes that are formed on at least one of the first substrate (21) and the second substrate (22) and are arranged in the alignment direction.
