a color generating layer, a barrier layer, and a light source;

the color generating layer comprising a plurality of color elements arranged in a two-dimensional array extending in a plurality of rows in a horizontal direction (X) and a plurality of columns in a vertical direction (Y);

the light source being arranged such that, during use, light generated by the light source may pass through an arrangement of the barrier layer and the color elements of the color generating layer;

the barrier layer being a straight barrier, comprising a barrier pattern of blocking structures and openings, and being arranged for providing the viewing angle of the first view and the viewing angle of the second view, and

the color generating layer having a row-rotation arrangement of the color elements, wherein the color elements of a row are shifted one position to the left in comparison to an adjacent row above the row.

2. The display device according to claim 1 , wherein in the color elements comprising at least red, green and blue color elements.

3. The display device according to claim 1 , wherein, in each column of the color generating layer, the color elements of the at least red, green and blue color are in a repeating sequence.

4. The display device according to claim 1 , wherein the color elements in each odd column are associated with one of the first and second views and the color elements in each even column are associated with another of the first and second views.

5. The display device according to claim 1 , wherein the color elements in each row have a repeating interleaved row sequence.

6. The display device according to claim 1 , wherein the light source is a backlight.

7. The display device according to claim 1 , wherein the color generating layer is a color filter plate.

8. The display device according to claim 7 , wherein the barrier layer is arranged between the light source and the color filter plate.

9. The display device according to claim 7 , wherein the color filter plate is arranged between the backlight and the barrier layer.

10. The display device according to claim 1 , wherein the display device comprises a light-switching layer comprising light switching elements that are individually associated with a single color element for controlling a transmission of light, during use, through that single color element and wherein the light switching elements are arranged for assigning one half of the plurality of color elements to the first view (V 1 ) and another half of the plurality of color elements to the second view (V 2 ).

11. The display device according to claim 1 , wherein the light source is an array of light emitting devices, each of the light emitting devices being arranged for producing white light and being associated with a corresponding one of the color elements of the color generating layer.

12. The display device according to claim 11 , wherein the light source comprises the color generating layer, each light emitting device being arranged as a color element for producing light of that color.

13. The display device according to claim 1 , wherein a horizontal spacing between color elements of the same color is 1.5 times the horizontal pitch (Wx) of one color element.

14. The display device according to claim 2 , wherein the color generating layer further comprises color elements of at least one additional color.

15. The display device according to claim 1 , wherein the display device generates images in a three-dimensional mode, the first view (V 1 ) being associated with a view for one eye of an observer, the second view (V 2 ) being associated with the other eye of the observer.

16. The display device according to claim 15 , wherein the display device is switchable between a two-dimensional mode and a three-dimensional mode.

17. A method for manufacturing a display device for displaying a first view (V 1 ) and a second view (V 2 ), the first view and the second view having a respective horizontal viewing angle; the method comprising:

providing a color generating layer, a barrier layer, and a light source;
