Abstract

The display device includes the first light-emitting element, a second light-emitting element, a first color filter through which light from the first light-emitting element passes, and a second color filter through which the light from the second light-emitting element passes. The relative positional relationship between the center of the first light-emitting element and the center of the first color filter is different from the relative positional relationship between the center of the second light-emitting element and the center of the second color filter.

Claims (54)

1. A display device comprising:

a first light-emitting element;

a second light-emitting element;

a sealing layer on the first light-emitting element and the second light-emitting element, the first light-emitting element and the second light-emitting element being in direct contact with a first surface of the sealing layer;

a first color filter through which light from the first light-emitting element passes; and

a second color filter through which light from the second light-emitting element passes,

wherein a relative positional relationship between a center of the first light-emitting element and a center of the first color filter in plan view is different from a relative positional relationship between a center of the second light-emitting element and a center of the second color filter in plan view, and

the first color filter and the second color filter are in direct contact with a second surface of the sealing layer opposite to the first surface.

2. The display device according to claim 1 ,

wherein the first light-emitting element, the first color filter, the second light-emitting element, and the second color filter are arranged in the display region,

an optical axis of the first light-emitting element is inclined to a center side of the display region from a normal line with respect to the first light-emitting element, and

the center of the first color filter in plan view is deviated to the center side of the display region further than the center of the first light-emitting element in plan view.

3. The display device according to claim 2 ,

wherein the second light-emitting element and the second color filter are arranged inside further than the first light-emitting element and the first color filter in the display region, and

when a deviation amount of the center of the first light-emitting element and the center of the first color filter in plan view is a first deviation amount, and a deviation amount of the center of the second light-emitting element and the center of the second color filter in plan view is a second deviation amount, the second deviation amount is smaller than the first deviation amount.

4. The display device according to claim 3 , further comprising:

a separation portion,

wherein a difference between the first deviation amount and the second deviation amount is made by a width of the separation portion arranged between the first color filter and the second color filter.

5. The display device according to claim 3 ,

wherein the first color filter is a red color filter,

the second color filter is a blue color filter, and

a difference between the first deviation amount and the second deviation amount is made by the width of a separation portion which separates the red color filter and the blue color filter.

6. The display device according to claim 3 , further comprising:

a third color filter,

wherein the difference between the first deviation amount and the second deviation amount is made by a width of the third color filter arranged between the first color filter and the second color filter.

7. The display device according to claim 6 ,

wherein the third color filter is a blue color filter.

8. The display device according to claim 1 , further comprising:

a filling layer formed on the first color filter and the second color filter; and

a cover glass formed on the filling layer.

9. The display device according to claim 8 ,

wherein the cover glass is made of a quartz glass.

10. The display device according to claim 8 ,

wherein an angle of light from the cover glass to air is larger than an angle of the light from the second light-emitting element to the sealing layer.

11. An electronic apparatus comprising:

the display device according to claim 1 .

12. An electronic apparatus comprising:

the display device according to claim 2 .

13. An electronic apparatus comprising:

the display device according to claim 3 .

14. An electronic apparatus comprising:

the display device according to claim 4 .

15. An electronic apparatus comprising:

the display device according to claim 5 .

16. An electronic apparatus comprising:

the display device according to claim 6 .

17. An electronic apparatus comprising:

the display device according to claim 7 .

18. An electronic apparatus comprising:

the display device according to claim 8 .

19. An electronic apparatus comprising:

the display device according to claim 9 .

20. An electronic apparatus comprising:

the display device according to claim 10 .
