Abstract

Provided is a display device that includes a first substrate that includes a first face and a peripheral region, a plurality of organic electroluminescent elements on the first substrate, and a plurality of color filters on the plurality of organic electroluminescent elements. The plurality of color filters includes at least a first color filter and a second color filter, and a part of the first color filter and a part of the second color filter are stacked in the peripheral region of the first substrate. The display device also includes a protection member on the plurality of color filters, a second substrate having a second face, where the second face faces the plurality of color filters, and a seal member between the first face and the second face in the peripheral region.

Claims (49)

1. A display device, comprising:

a first substrate that includes a first face and a peripheral region;

a plurality of organic electroluminescent elements on the first substrate;

a plurality of color filters on the plurality of organic electroluminescent elements, wherein

the plurality of color filters includes a first color filter and a second color filter, and

a part of the first color filter and a part of the second color filter are stacked in the peripheral region of the first substrate;

a protection member on the plurality of color filters;

a second substrate that includes a second face, wherein the second face faces the plurality of color filters; and

a seal member, between the first face and the second face, in the peripheral region.

2. The display device according to claim 1 , wherein

in the peripheral region, the part of the first color filter and the part of the second color filter are between the first face and the second face, and

the seal member is between the part of the first color filter and the part of the second color filter.

3. The display device according to claim 1 , wherein

the first color filter is configured to transmit a light beam of a first wavelength, and

the second color filter is configured to transmit a light beam of a second wavelength, different from the first wavelength, to color light of an organic electroluminescent element of the plurality of organic electroluminescent elements.

4. The display device according to claim 1 , wherein a film thickness of each of the first color filter and the second color filter is reducible.

5. The display device according to claim 1 , wherein each of the first color filter and the second color filter includes a single-layer colored film.

6. The display device according to claim 1 , wherein

the second color filter is on the first color filter, and

the second color filter is configured to transmit ultraviolet rays.

7. The display device according to claim 6 , wherein

the second color filter is configured to transmit red light, and

the first color filter is configured to transmit blue light.

8. The display device according to claim 1 , wherein in a case where the first substrate is bonded to the second substrate, a line width of the seal member is controllable.

9. An electronic apparatus, comprising:

a display device including:

a first substrate that includes a first face and a peripheral region;

a plurality of organic electroluminescent elements on the first substrate;

a plurality of color filters on the plurality of organic electroluminescent elements, wherein

the plurality of color filters includes a first color filter and a second color filter, and

a part of the first color filter and a part of the second color filter are stacked in the peripheral region of the first substrate;

a protection member on the plurality of color filters;

a second substrate that includes a second face, wherein the second face faces the plurality of color filters; and

a seal member, between the first face and the second face, in the peripheral region.

10. The electronic apparatus according to claim 9 , wherein

in the peripheral region, the part of the first color filter and the part of the second color filter are between the first face and the second face, and

the seal member is further between the part of the first color filter and the part of the second color filter.

11. The electronic apparatus according to claim 9 , wherein

the first color filter is configured to transmit a light beam of a first wavelength, and

the second color filter is configured to transmit a light beam of a second wavelength, different from the first wavelength, to color light of an organic electroluminescent element of the plurality of organic electroluminescent elements.

12. The electronic apparatus according to claim 9 , wherein each of the first color filter and the second color filter includes a single-layer colored film.

13. The electronic apparatus according to claim 9 , wherein

the second color filter is on the first color filter, and

the second color filter is configured to transmit ultraviolet rays.

14. The electronic apparatus according to claim 13 , wherein

the second color filter is configured to transmit red light, and

the first color filter is configured to transmit blue light.

15. The electronic apparatus according to claim 9 , wherein in a case where the first substrate is bonded to the second substrate, a line width of the seal member is controllable.

16. The electronic apparatus according to claim 9 , wherein a film thickness of each of the first color filter and the second color filter is reducible.
