Stereoscopic display device

A stereoscopic display device comprising:

• a display panel for displaying an image with a plurality of pixels;
• a switch liquid crystal panel that is arranged on a viewer side with respect to the display panel;
• a first polarizing plate arranged between the display panel and the switch liquid crystal panel;
• a second polarizing plate arranged on the viewer side with respect to the switch liquid crystal 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, and causing the switch liquid crystal panel to display the parallax barrier,
• wherein the transmitting region has a width greater than a width in the alignment direction of an opening of each of the pixels,
• the switch liquid crystal panel includes:
• a first substrate arranged on a side of the display panel;
• a first alignment film formed on the first substrate;
• a second substrate arranged so as to be opposed to the first substrate;
• a second alignment film formed on the second substrate;
• and
• a liquid crystal layer arranged between the first substrate and the second substrate,
• the rubbing direction of the first alignment film is parallel to the transmission axis of the first polarizing plate, and
• the rubbing direction of the second alignment film is parallel to the transmission axis of the second polarizing plate.
