Abstract

A display device includes a display panel on which a plurality of pixels are arranged in a matrix in a first direction and in a second direction intersecting the first direction, and a lenticular sheet which is disposed above the display panel and includes a plurality of polygonal prism lenses that are arranged in the second direction. Each of the polygonal prism lenses extends in a third direction intersecting the second direction, and includes a plurality of flat surfaces or curved surfaces.

Claims

1. A display device comprising:

a display panel comprising a plurality of pixels arranged in a matrix in a first direction and in a second direction intersecting the first direction; and

a lenticular sheet which is disposed above the display panel, and includes a plurality of polygonal prism lenses arranged in the second direction,

wherein each of the polygonal prism lenses longitudinally extends in a third direction intersecting the second direction, and includes a plurality of flat surfaces or curved surfaces.

2. The display device of claim 1, wherein a ratio of the flat surfaces to an entire surface of each of the polygonal prism lenses is equal to or larger than about 90%

3. The display device of claim 1, wherein the ratio of the flat surfaces to an entire surface of each of the polygonal prism lenses is equal to or larger than about 98%.

4. The display device of claim 1, wherein the third direction is parallel to the first direction.

5. The display device of claim 1, wherein the third direction is parallel to a diagonal direction of the pixels.

6. The display device of claim 1, wherein

adjacent pixels in the first direction represent the same color, and

adjacent pixels in the second direction represent different colors.

7. The display device of claim 1, wherein

each of the polygonal prism lenses includes flat surfaces and curved surfaces arranged alternately, and

a width of the flat surfaces is constant, and a radius of curvature of the curved surfaces is constant.

8. The display device of claim 7, wherein normal lines of the flat surfaces converge into a center of rotation of the curved surfaces.

9. The display device of claim 7, wherein each of the polygonal prism lenses has a symmetrical structure with respect to a center thereof, in the second direction.

10. A display device comprising:

a display panel comprising a plurality of pixels are arranged in a matrix in a first direction and in a second direction intersecting the first direction; and

a lenticular sheet which is disposed above the display panel, and includes a plurality of polygonal prism lenses arranged in the second direction,

wherein

each of the polygonal prism lenses longitudinally extends in a third direction intersecting the second direction, and

the third direction is parallel to a diagonal direction of the pixels.

11. The display device of claim 10, wherein

each of the polygonal prism lenses includes a plurality of flat surfaces or curved surfaces, and

a ratio of the flat surfaces to an entire surface of each of the polygonal prism lenses is equal to or larger than about 90%.

12. The display device of claim 11, wherein the ratio of the flat surfaces to an entire surface of each of the polygonal prism lenses is equal to or larger than about 98%.

13. The display device of claim 10, wherein

adjacent pixels in the first direction represent the same color, and

adjacent pixels in the second direction represent different colors.
