DISPLAY DEVICE
There is provided a display device excellent in resolution balance when a plurality of perspective pictures is used for stereoscopic display. The display device includes a display section including a plurality of sub-pixels, and displaying a plurality of perspective pictures in a screen, and an optical separation element optically separating the perspective pictures displayed on the display section. The sub-pixels are each with, in a planar view, a size in a long-side direction being less than three times a size in a short-side direction.
1 . A display device, comprising:
a display section including a plurality of sub-pixels, and displaying a plurality of perspective pictures in a screen; and
an optical separation element optically separating the perspective pictures displayed on the display section, wherein
the sub-pixels are each with, in a planar view, a size in a long-side direction being less than three times a size in a short-side direction.
2 . The display device according to claim 1 , wherein
the sub-pixels adjacent to each other are different in color in every direction of the screen.
3 . The display device according to claim 1 , wherein
the sub-pixels each have a hexagonal shape.
4 . The display device according to claim 1 , wherein
the sub-pixels are in a delta arrangement.
5 . The display device according to claim 1 , wherein
the optical separation element is
a parallax barrier including a plurality of light pass-through sections allowing light from the display section or light toward the display section to pass therethrough, and a plurality of light block sections allowing the light from the display section or the light toward the display section to be blocked.
6 . The display device according to claim 5 , wherein
the light pass-through sections and the light block sections in the parallax barrier are each stripe-shaped extending in a perpendicular direction of the screen.
7 . The display device according to claim 1 , wherein the sub-pixels each have a square shape in a planar view, and a size ratio between the perpendicular and horizontal directions of the screen is 4:3.
8 . The display device according to claim 1 , wherein
the sub-pixels are in a delta arrangement, and each have a hexagonal shape, and
a space between the sub-pixels adjacent to each other in a diagonal direction is smaller than a space between the sub-pixels adjacent to each other in the perpendicular direction of the screen.
9 . A display device comprising:
a display section including a plurality of sub-pixels, and displaying a plurality of perspective pictures in a screen; and
an optical separation element optically separating the perspective pictures displayed on the display section, wherein
the sub-pixels are arranged to have an arrangement pitch in a long-side direction less than three times an arrangement pitch in a short-side direction.
10 . The display device according to claim 9 , wherein
the sub-pixels adjacent to each other are different in color in every direction of the screen.
11 . The display device according to claim 9 , wherein
the sub-pixels each have a hexagonal shape.

the optical separation element is
a parallax barrier including a plurality of light pass-through sections allowing light from the display section or light toward the display section to pass therethrough, and a plurality of light block sections allowing the light from the display section or the light toward the display section to be blocked.
14 . The display device according to claim 13 , wherein
the light pass-through sections and the light block sections in the parallax barrier are each stripe-shaped extending in a perpendicular direction of the screen.
15 . The display device according to claim 9 , wherein the sub-pixels each have a square shape in a planar view, and a size ratio between the perpendicular and horizontal directions of the screen is 4:3.
16 . The display device according to claim 9 , wherein
the sub-pixels are in a delta arrangement, and each have a hexagonal shape, and
a space between the sub-pixels adjacent to each other in a diagonal direction is smaller than a space between the sub-pixels adjacent to each other in the perpendicular direction of the screen.
