Abstract

An organic electroluminescent device includes electrodes, an organic functional layer formed between facing electrodes, and separators for separating one of the electrodes into a strip, wherein the one electrode includes the first film formed with a vapor deposition method and the second film formed into a strip on the first film between the separators, and wherein the separators have dividing sections provided therein for electrically dividing the vapor deposited films formed on the top surfaces of the separators when the first film is formed.

Claims

1. An organic electroluminescent device comprising:

electrodes;

an organic functional layer formed between facing electrodes; and

separators for separating one of the electrodes into a strip,

wherein the one electrode includes the first film formed with a vapor deposition method and the second film formed into a strip on the first film between the separators, and

wherein the separators have dividing sections provided therein for electrically dividing the vapor deposited films formed on the top surfaces of the separators when the first film is formed.

2. A organic electroluminescent device according to claim 1, wherein the second film is formed so as to contact with at least one of two adjacent cathode separators among a plurality of the separators.

3. A organic electroluminescent device according to claim 1,

wherein the separators include divided separators which are divided into at least two parts, and

the dividing section is a gap between the divided separators.

4. A organic electroluminescent device according to claim 1, wherein the dividing section is a channel provided on the top surface of a separator.

5. An electronic apparatus having an organic electroluminescent device according to claim 1 as a display device.

6. A method for manufacturing an organic electroluminescent device having an organic functional layer formed in between facing electrodes, the method comprising:

forming separators which separate either of the electrodes into a strip;

forming an electrode film in between the separators with a vapor deposition method; and

placing a further electrode material on the electrode film which is formed in between the separators which include a divided separator that is divided into at least two parts, with the vapor deposition method.

7. A method for manufacturing an organic electroluminescent device according to claim 6, wherein the electrode material is a metal-dispersed ink or an electroconductive paste.

8. A method for manufacturing an organic electroluminescent device according to claim 6, wherein the electrode material is placed with a droplet ejecting method.

9. A method for manufacturing an organic electroluminescent device having an organic functional layer formed in between facing electrodes, the method comprising:

forming separators which separate one of the electrodes into a strip;

forming an electrode film in between the separators with a vapor deposition method;

placing a further electrode material on the electrode film which is formed in between the separators with the vapor deposition method; and

providing a channel which electrically divides an evaporated film to be formed on the top surface of the separator, when the electrode film will be formed.

10. A method for manufacturing an organic electroluminescent device according to claim 9, wherein the electrode material is a metal-dispersed ink or an electroconductive paste.

11. A method for manufacturing an organic electroluminescent device according to claim 9, wherein the electrode material is placed with a droplet ejecting method.
