Organic EL display device and method of manufacturing organic EL display device
View Patent ↗An organic EL display device includes: a lower electrode; an upper electrode; a first organic layer which is disposed between the lower electrode and the upper electrode and is formed of a plurality of layers including a light emitting layer formed of an organic material that emits light; a metal wire that extends between the pixels within the display region; and a second organic layer which is formed of a plurality of layers the same as that of the first organic layer and which comes into contact with a part of the metal wire and does not come into contact with the first organic layer. The upper electrode comes into contact with the metal wire in the periphery of the second organic layer. Accordingly, it is possible to uniformise the potential of the upper electrode without reducing the light emission area.
1. An organic EL display device comprising:
a lower electrode which is disposed for every pixel disposed in a matrix shape within a display region, and in which a potential is controlled for the every pixel;
an upper electrode which is disposed so as to cover the display region;
a first organic layer which is disposed between the lower electrode and the upper electrode and includes a plurality of layers including a light emitting layer formed of an organic material that emits light;
a metal wire that extends between the pixels within the display region; and
a second organic layer having the same layers as the layers which are included in the first organic layer, wherein
the second organic layer comes into contact with a part of the metal wire and does not come into contact with the first organic layer, and
the upper electrode comes into contact with the metal wire in the periphery of the second organic layer.
2. The organic EL display device according to claim 1 , further comprising:
a flattening film formed of the organic material covering a circuit which is formed on a substrate and includes the metal wire and a thin film transistor; and
an insulating bank that covers an end portion of the lower electrode which is formed on the flattening film among the lower electrode, the first organic layer, and the upper electrode, and electrically insulates the pixels,
wherein the upper electrode comes into contact with the metal wire through a contact hole opened in the flattening film and the insulating bank.
3. The organic EL display device according to claim 1 ,
wherein the upper electrode continuously comes into contact with the metal wire within the display region along the metal wire.
4. The organic EL display device according to claim 1 ,
wherein the metal wire vertically and horizontally extends so as to surround each of the pixels within the display region.
5. The organic EL display device according to claim 1 ,
wherein the first organic layer has the same light emitting layer in all of the pixels within the display region.
