Abstract

A display capable of suppressing color mixture caused by the diffraction of the light passing through the adjacent transmission color region of the color filter, even when a size of a light emitting element is small, and an electronic device including the display are provided. The display includes a plurality of light emitting elements, and a color filter having a transmission color region facing the plurality of light emitting elements, and a semi-transmissive region provided at a part of the transmission color region.

Claims (39)

1. A display comprising:

a plurality of light emitting elements; and

a color filter having a transmission color region facing the plurality of light emitting elements, and a semi-transmissive region provided at a part of the transmission color region, wherein the transmission color region includes two or more colored layers of different colors, and wherein

the semi-transmissive region includes:

a first semi-transmissive film; and

a second semi-transmissive film having a protruding part at a surface of the colored layer around the first semi-transmissive film.

2. The display according to claim 1 , wherein the semi-transmissive region is provided to face a border between the plurality of light emitting elements.

3. The display according to claim 1 , wherein

the first semi-transmissive film is provided at a surface of the colored layer.

4. The display according to claim 3 , wherein the semi-transmissive film is provided at a surface of the colored layer, the surface being on a side away from the plurality of light emitting elements.

5. The display according to claim 3 , wherein the semi-transmissive film is provided at a surface of the colored layer, the surface being on a side close to the plurality of light emitting elements.

6. The display according to claim 1 , wherein the light emitting elements are organic electroluminescent elements in which a first electrode, an organic layer including a light emitting layer, and a second electrode are laminated sequentially.

7. The display according to claim 6 , wherein the organic electroluminescent elements emit white light, and

the colored layers include a red colored layer, a green colored layer, and a blue colored layer extracting the white light as red light, green light, or blue light.

8. The display according to claim 6 , wherein the plurality of organic electroluminescent elements have a rectangular shape long in one direction, and arranged in a row direction parallel to a shorter side and in a column direction parallel to a longer side, and a pitch of the plurality of organic electroluminescent elements in the row direction is equal to or less than 30 μm.

9. A display comprising:

a plurality of light emitting elements; and

a color filter having a transmission color region facing the plurality of light emitting elements, and a semi-transmissive region provided at a part of the transmission color region, wherein the transmission color region includes two or more colored layers of different colors, and wherein

the semi-transmissive region includes:

a shielding film; and

a semi-transmissive film having a protruding part at a surface of the colored layer around the shielding film.

10. The display according to claim 9 , wherein the semi-transmissive region is provided to face a border between the plurality of light emitting elements.

11. The display according to claim 9 , wherein the semi-transmissive film is provided at a surface of the colored layer.

12. The display according to claim 11 , wherein the semi-transmissive film is provided at a surface of the colored layer, the surface being on a side away from the plurality of light emitting elements.

13. The display according to claim 11 , wherein the semi-transmissive film is provided at a surface of the colored layer, the surface being on a side close to the plurality of light emitting elements.

14. An electronic device comprising:

a display including:

a plurality of light emitting elements; and

a colored filter having a transmission color region facing the plurality of light emitting elements, and a semi-transmissive region provided at a part of the transmission color region, wherein the semi-transmissive region is provided at a position where a part of light entering from at least one of the light emitting elements included in the plurality of light emitting elements into the transmission color region passes through the semi-transmissive region, wherein the transmission colors, region includes two or more colored layers of different colors, and

the semi-transmissive region includes:

a first semi-transmissive film; and

a second semi-transmissive film having a protruding part at a surface of the colored layer around the first semi-transmissive film.

15. The electronic device according to claim 14 , wherein the light emitting element is an organic electroluminescent element in which a first electrode, an organic layer including a light emitting layer, and a second electrode are laminated sequentially.

16. The electronic device according to claim 15 , wherein the organic electroluminescent element emits white light, and

the colored layers include a red colored layer, a green colored layer, and a blue colored layer extracting the white light as red light, green light, or blue light.

17. The electronic device according to claim 15 , wherein the plurality of organic electroluminescent elements have a rectangular shape long in one direction, and arranged in a row direction parallel to a shorter side and in a column direction parallel to a longer side, and a pitch of the plurality of organic electroluminescent elements in the row direction is equal to or less than 30 μm.

18. The electronic device according to claim 14 , wherein the semi-transmissive region is provided to face a border between the plurality of light emitting elements.

19. The electronic device according to claim 14 , wherein the second semi-transmissive film is provided at a surface of the colored layer.

20. The electronic device according to claim 14 , wherein the first semi-transmissive film is provided at a surface of the colored layer on a side away from the plurality of light emitting elements.
