Abstract

Image devices with attenuation and modulation prevention for light received or projected through a display surface are disclosed. In one example, an image display device includes pixels arranged two-dimensionally, in which a pixel in a first pixel region includes a first light emitting region, a non-light emitting region having a higher visible light transmittance than the first light emitting region, and a first self-light emitting element that emits light from the first light emitting region. A pixel in a second pixel region other than the first pixel region includes a second light emitting region having a lower visible light transmittance than the non-light emitting region, and a second self-light emitting element that emits light from the second light emitting region.

Claims (50)

1. An image display device comprising a plurality of pixels arranged two-dimensionally,

wherein a first pixel in a first pixel region including some pixels among the plurality of pixels includes:

a first light emitting region;

a non-light emitting region having a higher visible light transmittance than the first light emitting region; and

a first self-light emitting element that emits light from the first light emitting region, and

a second pixel in a second pixel region other than the first pixel region among the plurality of pixels includes:

a second light emitting region having a lower visible light transmittance than the non-light emitting region; and

a second self-light emitting element that emits light from the second light emitting region.

2. The image display device according to claim 1 ,

wherein the non-light emitting region includes a region that transmits incident visible light, and

the first light emitting region and the second light emitting region include a region that reflects incident visible light without transmitting the visible light.

3. The image display device according to claim 1 , wherein a pixel closer to the first pixel region among the pixels in the second pixel region decreases a light-emitting luminance of the second light emitting region.

4. The image display device according to claim 3 , wherein a pixel luminance in the first pixel region and a pixel luminance in the second pixel region at a boundary portion between the first pixel region and the second pixel region are substantially equal.

5. The image display device according to claim 1 , wherein at least a part of the first pixel region is arranged so as to overlap a light receiving device that receives light incident through the image display device in plan view from a display surface side of the image display device.

6. The image display device according to claim 1 , wherein a pixel circuit connected to the first self-light emitting element in the first pixel region is arranged in the first light emitting region.

7. The image display device according to claim 1 ,

wherein each of the first self-light emitting element and the second self-light emitting element includes:

a lower electrode layer;

a display layer arranged on the lower electrode layer;

an upper electrode layer arranged on the display layer; and

a wiring layer arranged under the lower electrode layer and electrically connected to the lower electrode layer via a contact extending from the lower electrode layer in a lamination direction, and

the contact is arranged in the first light emitting region and the second light emitting region.

8. The image display device according to claim 7 , wherein at least a corner near an upper end of the contact has a laminated structure in which a transparent conductive layer is arranged on a metal layer.

9. The image display device according to claim 7 , wherein an inclination angle of a side surface of the contact with respect to the lamination direction changes stepwise or continuously, and an inclination angle of a vicinity of an upper end of the contact with respect to the lamination direction is larger than an inclination angle of a vicinity of a lower end of the contact with respect to the lamination direction.

10. The image display device according to claim 7 , wherein the lower electrode layer has a laminated structure in which a first transparent conductive layer, a metal layer, and a second transparent conductive layer are sequentially laminated.

11. The image display device according to claim 1 ,

wherein each pixel in the first pixel region and the second pixel region includes a plurality of color pixels,

each of the plurality of color pixels in the first pixel region has the first light emitting region and the non-light emitting region, and

each of the plurality of color pixels in the second pixel region has the second light emitting region.

12. The image display device according to claim 1 ,

wherein each pixel in the first pixel region and the second pixel region includes a plurality of color pixels, and

some color pixels among the plurality of color pixels in the first pixel region have the first light emitting region and the non-light emitting region, and color pixels other than the some color pixels have the first light emitting region without having the non-light emitting region.

13. The image display device according to claim 1 , wherein some pixels in the first pixel region have the non-light emitting region without having the first light emitting region, and pixels other than the some pixels have the first light emitting region without having the non-light emitting region.

14. The image display device according to claim 1 , wherein the first pixel region is provided at at least one of four corners of a display unit including the plurality of pixels.

15. An electronic apparatus comprising:

an image display device including a plurality of pixels arranged two-dimensionally; and

a light receiving device that receives light incident through the image display device,

wherein a first pixel in a first pixel region among the plurality of pixels includes:

a first light emitting region;

a non-light emitting region having a higher visible light transmittance than the first light emitting region; and

a first self-light emitting element that emits light from the first light emitting region;

a second pixel in a second pixel region other than the first pixel region among the plurality of pixels includes:

a second light emitting region having a lower visible light transmittance than the non-light emitting region; and

a second self-light emitting element that emits light from the second light emitting region, and

at least a part of the first pixel region is arranged so as to overlap the light receiving device in plan view from a display surface side of the image display device.

16. The electronic apparatus according to claim 15 , wherein the light receiving device receives light through the non-light emitting region.

17. The electronic apparatus according to claim 15 , wherein the first pixel region is a pixel region through which light incident on the light receiving device passes.

18. The electronic apparatus according to claim 15 , wherein the second pixel region decreases a light-emitting luminance of the second light emitting region as approaching the first pixel region.

19. The electronic apparatus according to claim 18 , wherein a pixel luminance in the first pixel region and a pixel luminance in the second pixel region at a boundary portion between the first pixel region and the second pixel region are substantially equal.

20. The electronic apparatus according to claim 15 , wherein the light receiving device includes at least one of an imaging sensor that photoelectrically converts light incident through the non-light emitting region, a distance measuring sensor that receives the light incident through the non-light emitting region and measures a distance, or a temperature sensor that measures a temperature on a basis of the light incident through the non-light emitting region.
