Abstract:
1. A display device comprising: a display unit that displays a synthetic image, the synthetic image being formed by dividing a plurality of images that are different from one another, and arraying these division images in a predetermined order; and an image separation unit that separates the plurality of images included in the synthetic image, wherein the image separation unit includes: a pair of substrates at least one of which has two types of electrode groups formed thereon, a reference voltage and a specific voltage different from the reference voltage being selectively applied to the two types of electrode groups; a liquid crystal layer sealed between the pair of substrates; a detection unit that detects a viewer's eye position; and a control unit that applies the specific voltage to one electrode groups that is selected from the electrode groups according to the viewer's eye position detected by the detection unit, so as to cause orientations of liquid crystal molecules in the liquid crystal layer to change, thereby to realize light-shielding sections that block light, wherein the electrode groups include a plurality of electrodes that are parallel to each other, on the substrate on which the two types of electrode groups are formed, out of the pair of substrates, the electrodes belonging to one of the two types of electrode groups and the electrodes belonging to the other electrode group are alternately arranged, and in the case where electrodes to which the specific voltage is applied are changed from a first electrode group to a second electrode group, the control unit switches the voltage applied to the first electrode group from the specific voltage to the reference voltage, and thereafter, switches the voltage applied to the second electrode group from the reference voltage to the specific voltage.
