Patent ID: 7956535

Claim:
A light emitting device comprising: a substrate; a plurality of pixel electrodes arranged in a matrix including a plurality of columns having two or more pixel electrodes arranged continuously in a first direction on the substrate; a counter electrode disposed opposite the plurality of pixel electrodes; a partition wall layer having a plurality of openings including a first opening and a second opening between the substrate and the counter electrode; and an interlayer insulating film disposed between the substrate and the plurality of pixel electrodes, wherein the plurality of pixel electrodes includes a first pixel electrode group including two or more of the plurality of pixel electrodes arranged continuously in the first direction, wherein the first pixel electrode group includes a first pixel electrode and a second pixel electrode arranged to be adjacent to each other and a third pixel electrode and a fourth pixel electrode arranged to be adjacent to each other, wherein a first division portion is disposed between the first pixel electrode and the second pixel electrode, wherein a second division portion is disposed between the third pixel electrode and the fourth pixel electrode, and wherein at least one light-emitting function layer including a plurality of layers including a light-emitting layer is formed between two or more pixel electrodes located between the first division portion and the second division portion in the first pixel electrode group and the counter electrode to cover the two or more pixel electrodes located between the first division portion and the second division portion, wherein the first opening receives the two or more pixel electrodes located between the first division portion and the second division portion, wherein the first division portion is formed of a part of the partition wall layer or a part of the interlayer insulating film, wherein the second division portion is formed of a part of the partition wall layer or a part of the interlayer insulating film, and wherein the second opening receives three or more pixel electrodes and the second opening receives more pixel electrodes than the first opening.
