Abstract: In a display device in which a shape of a parallax barrier is changed depending on the relative positional relation to the viewer, the occurrence of crosstalk is suppressed. Images are displayed in a part of a plurality of sub-pixels included in each pixel, and images are not displayed in the other sub-pixels. That is, a display area in the pixel is reduced. Thus, the occurrence of crosstalk can be suppressed. Further, sub-pixels have a square shape or a substantially square shape. Thus, even when sub-pixels which display images are selected depending on the relative positional relation to the viewer, the shape of the display area in the pixel does not change greatly. Therefore, even in the case where the positional relationship is changed (in the case where the arranged parallax barrier is changed), the occurrence of crosstalk can be suppressed without respect to the positional relationship.
