Organic electroluminescence display device
View Patent ↗An organic electroluminescence display device includes: a lower electrode that is made of a conductive inorganic material and formed in each of pixels arranged in a matrix in a display area; a light-emitting organic layer that is in contact with the lower electrode and made of a plurality of different organic material layers including a light-emitting layer emitting light; an upper electrode that is in contact with the light-emitting organic layer, formed so as to cover the whole of the display area, and made of a conductive inorganic material; and a conductive organic layer that is in contact with the upper electrode, formed so as to cover the whole of the display area, and made of a conductive organic material.
1. An organic electroluminescence display device comprising:
a substrate including a display area and a non-display area surrounding the display area;
a first electrode that is in the display area;
an insulating film that is on the first electrode and covers an edge portion of the first electrode;
a first organic layer that is in contact with the first electrode and includes a light-emitting layer emitting light;
a second electrode that is in contact with the first organic layer;
a second organic layer that is in contact with the second electrode;
a first inorganic layer;
a second inorganic layer that is on the first inorganic layer and in contact with the first inorganic layer in the non-display area; and
a third organic layer that is between the first inorganic layer and the second inorganic layer.
2. The organic electroluminescence display device according to claim 1 , wherein
a first distance and a second distance are distances between a top surface of the substrate and a top surface of the second organic layer;
the first distance is in a first area that is included the insulating film in plan view;
the second distance is in a second area that is not included the insulating film in plan view; and
the first distance is bigger than the second distance.
3. The organic electroluminescence display device according to claim 1 , further comprising a third inorganic layer that is in contact with the second organic layer and the first inorganic layer.
4. The organic electroluminescence display device according to claim 1 , wherein the second organic layer is inside the first inorganic layer and the second inorganic layer in plan view.
5. The organic electroluminescence display device according to claim 1 , wherein the second organic layer is conductive.
6. The organic electroluminescence display device according to claim 3 , wherein the third inorganic layer is conductive.
