2. The display device according to claim 1 , wherein the image display section displays a plurality of images with parallax.
3. The display device according to claim 2 , wherein the optical element is a parallax barrier, a lenticular lens, or a liquid crystal lens.
4. The display device according to claim 3 , wherein, when the optical element is the parallax barrier, a step barrier arrangement or a delta arrangement is a form of transmitting sections of the parallax barrier.
5. A display device comprising:
an image display section in which unit pixels each composed of a plurality of sub-pixels corresponding to a plurality of colors are arranged; and
an optical element having a window section allocating light emitted from the image display section in units of the sub-pixels to a plurality of viewpoints, wherein
the window section is controlled such that the image display section includes a plurality of RGB sub-pixel groups, each RGB sub-pixel group being associated with a respective viewpoint, and more than a predetermined number of the RGB sub-pixel groups do not exist along a straight line in any direction,
the optical element is a parallax barrier, a lenticular lens, or a liquid crystal lens,
when the optical element is the parallax barrier, a step barrier arrangement or a delta arrangement is a form of transmitting sections of the parallax barrier, and
when the transmitting sections of the parallax barrier are in the step barrier arrangement, steps of the step barrier arrangement are arranged so as to be discontinuous.
6. The display device according to claim 1 , wherein a stripe arrangement is a basic form of the color arrangement of the RGB sub-pixels in the image display section.
7. The display device according to claim 1 , wherein the optical element provides a plurality of images displayed by the image display section three-dimensionally to an image observer.
8. The display device according to claim 1 , wherein the optical element provides a plurality of images displayed by the image display section separately to a plurality of image observers.
9. A display device comprising:
an image display section in which unit pixels each composed of a plurality of sub-pixels corresponding to a plurality of colors are arranged; and
an optical element having a window section allocating light emitted from the image display section in units of the sub-pixels to a plurality of viewpoints, wherein
a color arrangement of the sub-pixels of the image display section or an arrangement of the window section of the optical element is set such that, when the image display section is viewed from each of the plurality of viewpoints, in an arrangement of colors of light allocated by the window section of the optical element, a same color is not arranged linearly in a predetermined number of sub-pixels or more in succession in any of a row direction, a column direction, and an oblique direction,
the image display section displays a plurality of images with parallax,
the optical element is a parallax barrier, a lenticular lens, or a liquid crystal lens,
when the optical element is the parallax barrier, a step barrier arrangement or a delta arrangement is a basic form of transmitting sections of the parallax barrier, and
when the transmitting sections of the parallax barrier are in the step barrier arrangement, steps of the step barrier arrangement are arranged so as to be discontinuous.
10. A display device comprising:
an image display section in which unit pixels each composed of a plurality of sub-pixels corresponding to a plurality of colors are arranged; and
an optical element having a window section allocating light emitted from the image display section in units of the sub-pixels to a plurality of viewpoints, wherein
the window section is controlled such that, in each of the plurality of viewpoints, a predetermined number of adjacent sub-pixels corresponding to a given color and a given viewpoint do not exist along a straight line in any direction,
the image display section displays a plurality of images with parallax,
the optical element is a parallax barrier, a lenticular lens, or a liquid crystal lens,
when the optical element is the parallax barrier, a step barrier arrangement or a delta arrangement is a basic form of transmitting sections of the parallax barrier, and
