Abstract

An organic electroluminescent device includes a pixel region in which a plurality of pixels is disposed on a support substrate, each pixel having an electroluminescent element in which at least a first electrode layer, a light-emitting layer, and a second electrode layer are laminated in that order at an upper layer side of an insulating film; a first conductive pattern portion provided at a lower layer side of the insulating film for applying a potential to the second electrode layer; and a second conductive pattern portion which is composed of a conductive film having a sheet resistance lower than that of the second electrode layer and which is provided at the upper layer side of the insulating film to connect the second electrode layer to the first conductive pattern portion. In this organic EL device, the second conductive pattern portion has a third conductive pattern portion which is provided on an upper surface of the first conductive pattern portion at a contact portion composed of a non-forming region of the insulating film and which is in contact with the first pattern portion.

Claims (17)

1. An organic electroluminescent device comprising:

a substrate that has an element region and a connection region outside of the element region;

a light-emitting element that has a first electrode, a second electrode, a light-emitting layer disposed between the first electrode and the second electrode, the light-emitting element disposed in the element region;

a first conductive film that is disposed in a first layer between the substrate and the second electrode;

a second conductive film that is disposed in a second layer between the first layer and the second electrode, and

an auxiliary wiring that extends from the element region to the connection region, wherein:

the first conductive film and the second conductive film are disposed in the connection region;

the second electrode extends from the element region to the connection region;

the second electrode, the first conductive film and the second conductive film are electrically connected in the connection region; and

in the connection region, the auxiliary wiring is electrically connected to the second electrode and the second conductive film and the auxiliary wiring is disposed between the second electrode and the second conductive film.

2. The organic electroluminescent device according to claim 1 ,

wherein the first and second conductive films are arranged along a first side of the substrate.

3. The organic electroluminescent device according to claim 1 , further comprising:

an insulating layer arranged between the first and second layers;

wherein the first and second conductive films are electrically connected through a contact portion arranged in the insulating layer.

4. The organic electroluminescent device according to claim 1 ,

wherein the light-emitting element has first and second light-emitting elements, and in a plan view, the auxiliary wires are arranged between the first and second light-emitting elements.
