Abstract

According to one embodiment, an organic EL device includes an insulating substrate, first and second interlayer insulators, pixel electrodes, an organic layer, and a counter electrode. The first interlayer insulator is positioned above the insulating substrate. The second interlayer insulator is positioned on the first interlayer insulator and provided with slits. The pixel electrodes are arranged on the second interlayer insulator. Two or more of the pixels are adjacent to each other with one of regions corresponding to the slits interposed therebetween. The organic layer is positioned on the pixel electrodes and includes an emitting layer. The counter electrode is positioned above the organic layer.

Claims (38)

1. An organic EL device comprising:

an insulating substrate;

a first interlayer insulator positioned above the insulating substrate;

a second interlayer insulator positioned on the first interlayer insulator and provided with slits;

pixel electrodes arranged on the second interlayer insulator, two or more of the pixel electrodes being adjacent to each other with a gap therebetween, the gap being positioned above one of the slits;

an organic layer including first regions covering the pixel electrodes and second regions positioned in the slits, the organic layer emitting light at positions corresponding to the pixel electrodes; and

a counter electrode positioned above the organic layer,

wherein the slits includes:

one or more first slits dividing the second interlayer insulator at a position corresponding to the gap between the pixel electrodes; and

one or more second slits dividing portions of the second interlayer insulator that corresponds to the pixel electrodes.

2. An organic EL device comprising:

an insulating substrate;

an interlayer insulator formed above the insulating substrate;

insulating portions formed above the interlayer insulator and spaced apart from each other;

thin-film transistors arranged between the insulating substrate and the insulating portions;

pixel electrodes formed on the insulating portions, the pixel electrodes being electrically connected to the thin-film transistors, respectively;

an organic layer including first regions formed above the pixel electrodes and second regions positioned between the insulating portions, the organic layer emitting light at positions corresponding to the pixel electrodes; and

a counter electrode formed above the organic layer,

wherein two or more of the insulating portions are positioned below one of the pixel electrodes.

3. An organic EL device comprising:

an insulating substrate;

a first interlayer insulator positioned above the insulating substrate;

a second interlayer insulator positioned on the first interlayer insulator and provided with slits;

pixel electrodes arranged on the second interlayer insulator, two or more of the pixel electrodes being adjacent to each other with a gap therebetween, the gap being positioned above one of the slits;

an organic layer positioned on the pixel electrodes and including an emitting layer; and

a counter electrode positioned above the organic layer,

wherein the slits include:

one or more first slits dividing the second interlayer insulator at a position corresponding to the gap between the pixel electrodes; and

one or more second slits dividing portions of the second interlayer insulator that corresponds to the pixel electrodes.

4. An organic EL device comprising:

an insulating substrate;
