| description | Obtained is a configuration of a stereoscopic display device wherein luminance variation and increase of crosstalk can be reduced over a period before and after the switching of the parallax barrier. The stereoscopic display device includes: a display panel for displaying an image with a plurality of pixels; 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 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, with use of a predetermined barrier switching pitch as a minimum unit, and causing the switch liquid crystal panel to display the parallax barrier. The plurality of pixels have openings each of which has a width A in the alignment direction, the width A satisfying the expressions of A Wsl−2Pe, and A Wbr−2Pe where Wsl is a width of the transmitting region, Wbr is a width of the non-transmitting region BR, and Pe is the barrier switching pitch. |
