Abstract

A display device including a display part including a pixel of a first series having a first horizontal pixel width and a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width, the pixels of the first series and the pixels of the second series being arrayed alternately in each of a horizontal direction and a vertical direction, and a light beam control part that controls a light beam from the display part or a light beam toward the display part.

Claims

1. A display device, comprising:

pixels of a first series including first pixels and second pixels;

pixels of a second series arranged between the pixels of the first series in a first direction;

a parallax barrier comprised of (a) first series barriers and (b) second series barriers that are arranged between the first series barriers in the first direction,

wherein,

the first series barriers are configured to be in a transmissive state,

the second series barriers are configured to be in a non-transmissive state,

the first pixels of the first series are configured to display a plurality of first viewpoint images via the first series barriers,

the second pixels of the first series are configured to display a plurality of second viewpoint images via the first series barriers, and

the pixels of the second series are configured to display a black color or a gray color.

2. The display device according to claim 1, wherein the distance between the pixels of the first series in the first direction is substantially equal to a width of the pixels of the first series in the first direction.

3. The display device according to claim 1, wherein the distance between the pixels of the first series in the first direction is shorter than a width of the pixels of the first series in the first direction.

4. The display device according to claim 1, wherein the distance between the pixels of the first series in the first direction is larger than a width of the pixels of the first series in the first direction.

5. The display device according to claim 1, wherein the pixels of the second series are arranged between the pixels of the first series in a second direction which crosses the first direction.

6. The display device according to claim 5, wherein a central coordinate in the first direction of each pixel of the first series is equal to a central coordinate in the first direction of a pixel of the second series neighboring on the pixel of the first series in the second direction.

7. The display device according to claim 1, the second series barriers are switchable liquid crystal barriers.

8. The display device according to claim 1, wherein the first and second series barriers are switchable liquid crystal barriers.

9. The display device according to claim 1, wherein the first series barriers and the second series barriers extend in a predetermined direction.

10. The display device according to claim 1, wherein a width of the first series barriers is smaller than a width of the pixels of the first series in the first direction.

11. The display device according to claim 1, further comprising an illuminator, wherein the pixels of the first series and the pixels of the second series are present between the illuminator and the parallax barrier.

12. The display device according to claim 1, further comprising an illuminator, wherein the parallax barrier is present between the illuminator and the pixels of the first and second series.

13. The display device of claim 1, wherein, for a given group of four neighboring pixels of the first series, two of the pixels are a one color and two of the pixels are of another color.

14. The display device of claim 1, wherein:

the display device is configured to perform a first display mode and a second display mode,

in the first display mode, each of the pixels of the second series is configured to display a same color with each of the pixels of the first series which is adjacent to the each of the pixels of the second series in the first direction, and

in the second display mode, the pixels of the second series are configured to display the black color or the gray color.

15. The display device of claim 14, wherein:

the display device is configured to perform a first display mode and a second display mode,

in the first display mode, each of the pixels of the second series is configured to display a same color with each of the pixels of the first series which is adjacent to the each of the pixels of the second series in a second direction which crosses the first direction.

16. A display device, comprising:

pixels of a first series including first pixels and second pixels;

pixels of a second series arranged between the pixels of the first series in a first direction;

a parallax barrier comprised of openings and barrier parts, the openings being arranged between the barrier parts in the first direction,

wherein,

the barrier parts are configured to be in a non-transmissive state,

the first pixels of the first series are configured to display a plurality of first viewpoint images via the openings,

the second pixels of the first series are configured to display a plurality of second viewpoint images via the openings, and

the pixels of the second series are configured to display a black color or a gray color.

17. A display device, comprising:

pixels of a first series including first pixels and second pixels;

pixels of a second series arranged between the pixels of the first series in a first direction; and

a lens,

wherein,

the first pixels of the first series display a plurality of images via the lens;

the second pixels of the first series are configured to display a plurality of second viewpoint images via the lens; and

the pixels of the second series are configured to display a black color or a gray color.
