Abstract: According to one embodiment, a display device includes a display unit which displays an image, a barrier unit including a plurality of barrier regions, each of the barrier regions including two nontransmissive regions which block light transmitted from the display unit and one transmissive region which is arranged between the two nontransmissive regions and allows light transmitted from the display unit to pass through, and a control unit. The control unit controls the barrier pitch of the barrier regions, according to viewer's position. Further, the control unit controls each of edge-units constituting the transmissive region into a state of transmissive or nontransmissive.
