Abstract

Provided is an organic EL device including a first substrate, a first organic EL element and a second organic EL element which is provided on the first substrate, a sealing layer which covers the first organic EL element and the second organic EL element, and a color filter which is provided on the sealing layer. The color filter includes a coloring layer overlapping the first organic EL element in a planar view, and a resin layer overlapping the second organic EL element in a planar view.

Claims (40)

1. An organic EL device comprising:

a first substrate;

a first organic EL element and a second organic EL element which are provided on the first substrate;

a sealing layer which covers the first organic EL element and the second organic EL element; and

a color filter which is provided on the sealing layer,

wherein the color filter includes a coloring layer which overlaps the first organic EL element in a planar view, and a transparent layer which overlaps the entire second organic EL element but does not overlap the first organic EL element in the planar view, the second organic EL element does not have an overlapping coloring layer in the planar view, such that the second organic EL element transmits light that does not pass through a coloring layer.

2. The organic EL device according to claim 1 ,

wherein the first organic EL element and the second organic EL element are disposed on the first substrate so as to be adjacent to each other in one direction, and

wherein the transparent layer is provided between the first organic EL element and the second organic EL element in the one direction so as to come in contact with the coloring layer.

3. An electronic device comprising the organic EL device according to claim 2 .

4. The organic EL device according to claim 1 , further comprising:

a first driving transistor which is provided on the first substrate, and is connected to the first organic EL element via a first contact portion; and

a second driving transistor which is connected to the second organic EL element via a second contact portion,

wherein the coloring layer is provided in such a manner that the first contact portion and the second contact portion are overlapped with each other in a planar view.

5. An electronic device comprising the organic EL device according to claim 4 .

6. The organic EL device according to claim 1 ,

wherein a main component of the coloring layer and the transparent layer is a photosensitive resin having light transmissivity.

7. The organic EL device according to claim 6 ,

wherein the photosensitive resin is a photosensitive acrylic resin.

8. The organic EL device according to claim 1 ,

wherein each of the first organic EL element and the second organic EL element include a pixel electrode having light transmissivity, a counter electrode having both light transmissivity and reflectivity, and a light-emitting function layer disposed between the pixel electrode and the counter electrode,

wherein the organic EL device further comprise a reflective layer between a substrate main body of the first substrate and the pixel electrode, and

wherein in the first organic EL element and the second organic EL element, optical distances between the reflective layer and the counter electrode are different from each other.

9. The organic EL device according to claim 1 , further comprising:

a second substrate having light transmissivity; and

a filler provided between the second substrate and the color filter.

10. The organic EL device according to claim 1 ,

wherein a light-emitting area of the second organic EL element is smaller than a light-emitting area of the first organic EL element.

11. The organic EL device according to claim 1 ,

wherein the light-emitting area of the second organic EL element is larger than the light-emitting area of the first organic EL element.

12. An electronic device comprising the organic EL device according to claim 1 .

13. The organic EL device according to claim 1 , the second organic EL element including a pixel electrode having an opening portion, and the transparent layer overlapping the opening portion of the pixel electrode in the planar view.

14. An organic EL device comprising:

a first substrate;

a first organic EL element and a second organic EL element which are provided on the first substrate;

a sealing layer which covers the first organic EL element and the second organic EL element; and

a color filter which is provided on the sealing layer,

wherein the color filter includes a coloring layer which overlaps the first organic EL element in a planar view, and a resin layer which overlaps the entire second organic EL element but does not overlap the first organic EL element in the planar view, the second organic EL element does not have an overlapping coloring layer in the planar view, such that the second organic EL element transmits light that does not pass through a coloring layer, and

wherein the coloring layer is formed of a resin which contains a coloring material, and the resin layer is formed of a resin which does not contain a coloring material.

15. An electronic device comprising the organic EL device according to claim 14 .
