Abstract: A liquid crystal display device includes a liquid crystal panel, a light blocking barrier, and a sensor. The apparatus has a barrier driving controlling unit, a display controlling unit, and a display mode decision unit to decide a display mode of an image to be displayed on the panel. The barrier driving controlling unit controls, when it is decided that the display mode is a first mode, driving of the barrier so that the position of the light blocking section of the barrier is moved in response to the position of the viewer detected by the sensor. The display controlling unit controls, when it is decided that the display mode is a second mode, the display of the panel so that the display position of the left-eye and the right-eye images on the panel is moved in response to the position of the viewer detected by the sensor.

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.

A liquid crystal parallax barrier panel is arranged on a display panel. The liquid crystal parallax barrier panel includes a barrier substrate having barrier electrodes formed thereon, a common substrate provided with a common electrode, and liquid crystal held between the barrier substrate and the common electrode. Barriers are formed by applying a voltage to the barrier electrodes.
