Abstract: According to one embodiment, a display device includes a switching liquid crystal unit, a display, and a controller. The switching liquid crystal unit includes optical elements switching an aperture pattern including an aperture portion and a light-shielding portion. The display overlaps the switching liquid crystal unit and displays parallax images including right and left eye images. The controller acquires positional information relating to a position of a viewer, and controls a position of the aperture pattern. The controller switches the aperture pattern from a first aperture pattern to a second aperture pattern so that a right eye always views the right eye image and a left eye always views the left eye image, and starts the switching before the viewer moves to an optimal switching position where a luminance viewed from the first aperture pattern is substantially equal to a luminance viewed from the second aperture patterns.

Abstract: In a three dimensional display device of a parallax barrier system in which an IPS-mode liquid crystal display panel is used as a liquid crystal display panel for displaying images and a TN-mode liquid crystal panel is used as a parallax barrier panel, alignment axes of a counter substrate and a barrier substrate constituting the parallax barrier panel are set to 45 degrees and 135 degrees, respectively, with respect to a horizontal direction of a screen. This allows an improvement in the viewing angle characteristics of the parallax barrier panel and an improvement in the viewing characteristics of the overall three dimensional display device of the parallax barrier system. Thus, even when the line of sight moves, crosstalk between an image for a right eye and an image for a left eye can be prevented thereby allowing a viewer to recognize excellent three dimensional images.
