Abstract

An organic EL device according to the present application includes a substrate, a plurality of organic EL elements arranged on the substrate, the plurality of organic EL elements including an organic light-emitting layer interposed between an anode and a cathode, a plurality of connection terminals disposed on the substrate, a sealing layer covering the plurality of organic EL elements such that the plurality of organic EL elements lie between the substrate and the sealing layer, and an organic layer formed above the sealing layer. The organic layer and the sealing layer have an opening portion that exposes at least one of the plurality of connection terminals.

Claims (43)

1. An organic EL device comprising:

a substrate;

a plurality of organic EL elements arranged on the substrate, the plurality of organic EL elements including a first organic EL element and a second organic EL element, the plurality of organic EL elements each including an organic light-emitting layer interposed between an anode and a cathode;

a display region where the plurality of organic EL elements is arranged on;

a plurality of connection terminals each disposed on the substrate;

a first coloration layer formed above the first organic EL element;

a second coloration layer formed above the second organic EL element;

wherein the first coloration layer and the second coloration layers are each a single layer, and the first coloration layer and the second coloration layer overlap in a region between the plurality of connection terminals and the display region.

2. An organic EL device according to claim 1 ,

wherein the plurality of organic EL elements include a third organic EL element, and a third coloration layer is formed above a third organic EL element,

wherein the third coloration layer is a single layer, and the second coloration layer and the third coloration layer overlap in between the connection terminal and the display region.

3. An organic EL device according to claim 1 , further comprising:

a pixel electrode which functions as an anode; and

a partition wall insulating multiple pixel electrodes from one another, wherein

an end portion of second coloration layer at a side facing the display region overlaps a portion of the partition wall positioned outside of the display region.

4. An organic EL device comprising:

a substrate;

a first organic EL element and a second organic EL element formed on a display region of the substrate;

a sealing layer covering the first organic EL element and the second organic EL element such that the first organic EL element and the second organic EL element lie between the substrate and the sealing layer;

a plurality of connection terminals disposed on a terminal portion of the substrate;

a first coloration layer formed above the sealing layer, the first coloration layer overlapping the first organic EL element in the display region; and

a second coloration layer formed above the sealing layer, the second coloration layer overlapping the second organic EL element in the display region,

wherein the first coloration layer and the second coloration layer overlap each other at a region between the display region and the terminal portion.

5. An organic EL device according to claim 4 , further comprising:

a third organic EL element formed on the display region of the substrate; and

a third coloration layer formed above the sealing layer, the third coloration layer overlapping the third organic EL element in the display region,

wherein the third coloration layer overlaps the first coloration layer and the second coloration layer at the region between the display region and the terminal portion.

6. An organic EL device according to claim 4 ,

wherein the first coloration layer overlapping the first organic EL element is a single layer, and

wherein the second coloration layer overlapping the second organic EL element is a single layer.

7. An organic EL device according to claim 5 ,

wherein the third coloration layer overlapping the third organic EL element is a single layer.

8. An organic EL device according to claim 4 , wherein the sealing layer comprises an opening portion.

9. An organic EL device according to claim 4 , wherein at least one of the plurality of connection terminals is completely surrounded by an opening portion of the sealing layer.

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

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

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

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

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

15. An electronic apparatus comprising the organic EL device according to claim 6 .

16. An electronic apparatus comprising the organic EL device according to claim 7 .

17. An electronic apparatus comprising the organic EL device according to claim 8 .

18. An electronic apparatus comprising the organic EL device according to claim 9 .
