A display device that can be made to be smaller and thinner. The display device includes a light source including a plurality of emitting regions disposed in a plane, a light emission controller which performs switching control of each emitting region between an illuminating state and a blacked out state, a transmission type image display panel including a plurality of pixels through which light emitted from the light source is transmitted, an image signal output which sends each pixel a set of associated image data, and a light directing member which includes a structure for directing light that has passed through the pixels and which is disposed opposingly to the transmission type image display panel. A set of the emitting regions are arranged in the horizontal direction of the transmission type image display panel to oppose to an associated pixel of the transmission type image display panel. |

| Claim: |
1. A display device comprising: a light source including a plurality of emitting regions disposed in a plane with each emitting region having at least an illuminating state and a blacked out state; a light emission controller which performs switching control of each emitting region between its illuminating state and blacked out state; a transmission type image display panel including a horizontal direction and a plurality of pixels through which light emitted from the light source is transmitted to display an image on the display panel; an image signal output which sends each pixel a set of associated image data; and a light directing member which includes a structure for directing light that has passed through the pixels and which is disposed opposingly to the transmission type image display panel, wherein a set of the emitting regions are arranged in the horizontal direction of the transmission type image display panel to oppose to an associated pixel of the transmission type image display panel, the image signal output sequentially sends each pixel a set of associated image data for a plurality of images, and the light emission controller controls each emitting region to illuminate only a part of the plurality of the emitting regions and to sequentially switch the illuminated emitting regions. |
| Claim: |
2. A display device according to claim 1, wherein the transmission type image display panel displays colored images and each of the pixels respectively displays red, blue or green. |
| Claim: |
3. A display device according to claim 1, wherein the transmission type image display panel includes a vertical direction and the pixels of the transmission type image display panel are divided into three sections arranged in the vertical direction of the transmission type image display panel and each of which has a display region of red, blue and green. |
| Claim: |
4. A display device according to claim 1, wherein the light emission controller controls the illumination of the emitting regions that are opposed to pixels of the transmission type image display panel at the same time with the switching of the pixels for the plurality of images displayed on the display panel. |
| Claim: |
5. A display device according to claim 1, wherein the light source is an area light emitting device. |
| Claim: |
6. A display device according to claim 1 wherein the transmission type image display panel is a liquid crystal panel. |
| Claim: |
7. A display device according to claim 1 wherein the directing member is a lenticular lens. |
| Claim: |
8. A display device according to claim 1 wherein the directing member is a parallax barrier. |
| Claim: |
9. A display device according to claim 1 wherein the light directed by the light directing member converges to at least two observation points. |
| Claim: |
10. A display device according to claim 9 wherein the two observation points are separated with a distance corresponding to a parallax or a distance shorter than the parallax. |
| Claim: |
11. A display device comprising: a light source including a plurality of emitting regions disposed in a plane; a transmission type image display panel including a horizontal direction and a plurality of pixels through which light emitted from the light source is transmitted for the display panel to enable display of an image; and a light directing member disposed to oppose the transmission type image display panel and including a means for directing the light from the light source, wherein the emitting regions of the light source are arranged in the horizontal direction of the transmission type image display panel to oppose a pixel of the transmission type image display panel. |
| Claim: |
12. A display device according to claim 11, wherein the transmission type image display panel displays colored images and each of the pixels respectively display red, blue or green. |
| Claim: |
13. A display device according to claim 11, wherein the transmission type image display panel includes a vertical direction and the pixels of the transmission type image display panel are divided into three sections arranged in the vertical direction of the transmission type image display panel and each of which has a display region of red, blue and green. |
| Claim: |
14. A display device according to claim 11, wherein a plurality of images are displayed on the display panel and the light emission controller controls the illumination of the emitting regions that are opposed to pixels of the transmission type image display panel at the same time with the switching of the pixels for the plurality of images displayed on the display panel. |
| Claim: |
15. A display device according to claim 11, wherein the light source is an area light emitting device. |
| Claim: |
16. A display device according to claim 11 wherein the transmission type image display panel is a liquid crystal panel. |
| Claim: |
17. A display device according to claim 11 wherein the directing member is a lenticular lens. |
| Claim: |
18. A display device according to claim 11 wherein the directing member is a parallax barrier. |
| Claim: |
19. A display device according to claim 11 wherein the light directed by the light directing member converges to at least two observation points. |
| Claim: |
20. A display device according to claim 19 wherein the two observation points are separated with a distance corresponding to a parallax or a distance shorter than the parallax. |
