Abstract
An organic electroluminescence device includes: a first electrode layer; an insulating film arranged on the first electrode layer; an organic layer that is arranged on the insulating film, and is in contact with the first electrode layer at an opening portion provided in the insulating film; a second electrode layer arranged on the organic layer; and a metal layer that is in contact with an end surface of the organic layer and an end surface of the second electrode layer, and is arranged on the second electrode layer.
Claims15
An organic electroluminescence device comprising:
- a first electrode layer;
- an insulating film arranged on the first electrode layer;
- an organic layer arranged on the insulating film, and being in contact with the first electrode layer at a first opening portion provided in the insulating film;
- a second electrode layer arranged on the organic layer;
- and
- a metal layer arranged on the second electrode layer, the metal layer being in contact with an end surface of the organic layer and an end surface of the second electrode layer.
A manufacturing method of an organic electroluminescence device, comprising:
- forming a first electrode layer;
- forming an insulating film on the first electrode layer;
- removing a part of the insulating film until a part of a surface of the first electrode layer is exposed so as to form a first opening portion;
- forming an organic layer and a second electrode layer in this order on the insulating film, and bringing the first electrode layer and the organic layer into contact with each other at the first opening portion;
- and
- forming a metal layer on the second electrode layer, and bringing the metal layer into contact with an end surface of the organic layer and an end surface of the second electrode layer.
