Abstract

In an organic electroluminescent display device comprising a wiring layer, an insulating layer, a first electrode, an organic electroluminescent layer, and a second electrode, wiring which conducts with a second electrode is arranged between light emitting pixels, and is provided either between an organic electroluminescent layer and the second electrodes, or on top of the second electrodes.

Claims (27)

1. An organic electroluminescent display device comprising a wiring layer, an insulating layer, a first electrode, an organic electroluminescent layer, and a second electrode that are laminated on a substrate in sequence from the substrate side, wherein:

the second electrode is a layer above the organic electroluminescent layer and covers the organic electroluminescent layer;

the organic electroluminescent display device has a plurality of light emitting pixels radiating light that is emitted from the organic electroluminescent layer and is transmitted through the second electrode; and

the organic electroluminescent display device further comprises wiring that conducts with the second electrode, the wiring being arranged between the light emitting pixels and being provided at the upper side of the organic electroluminescent layer either

on top of and in contact with the organic electroluminescent layer, or

on top of the second electrode such that the wiring is in contact with the upper surface of the second electrode.

2. The organic electroluminescent display device according to claim 1 , wherein the wiring is configured to be continuous such that at least a part of mutual film forming patterns of the respective wiring is overlapped.

3. The organic electroluminescent display device according to claim 2 , wherein alternate wirings intersect so as to be connected to each other in a region corresponding to a region outside of the light emitting pixels.

4. An organic electroluminescent display device comprising:

a substrate;

a wiring layer;

an insulating layer;

a first electrode;

an organic electroluminescent layer;

a second electrode; and

wiring which conducts with the second electrode, wherein

the second electrode is a layer above the organic electroluminescent layer and covers the organic electroluminescent layer,

the organic electroluminescent display device has a plurality of light emitting pixels radiating light that is emitted from the organic electroluminescent layer and is transmitted through the second electrode, and

the wiring is arranged between the light emitting pixels, and is provided at the upper side of the organic electroluminescent layer either

on top of and in contact with the organic electroluminescent layer, or

on top of the second electrode such that the wiring is in contact with the upper surface of the second electrode.

5. The organic electroluminescent display device according to claim 4 , wherein the wiring comprises a plurality of shape elements and at least a part of the shape elements is mutually overlapped.

6. The organic electroluminescent display device according to claim 5 , wherein the plurality of shape elements are arranged in a mutually staggered form.

7. The organic electroluminescent display device according to claim 5 , wherein the plurality of shape elements includes a plurality of types of shape elements, and constitutes the wiring in which at least a part of the shape elements of the plurality of types is mutually overlapped.

8. The organic electroluminescent display device according to claim 7 , wherein the shape elements of the plurality of types comprise a first shape element and a second shape element, and the second shape element is arranged on an outside periphery of a region where the first shape element is arranged.

9. The organic electroluminescent display device according to claim 8 , wherein the plurality of second shape elements are arranged with positions thereof shifted from each other on the outside periphery of the region where the first shape element is arranged.

10. The organic electroluminescent display device according to claim 4 , wherein the wiring comprises a plurality of shape elements, at least a part of the shape elements is mutually overlapped, and each shape element has a dimension exceeding the dimension of each of the light emitting pixels by no more than the length with which each of the shape elements overlap with each other.
