Claim:
1. An organic electroluminescence display device comprising: a circuit board; an element layer which contains an organic electroluminescence film and a positive electrode and a negative electrode sandwiching the organic electroluminescence film and which is formed on the circuit board; a partition wall partitioning the element layer into pieces for pixels; and a sealing film sealing the element layer, wherein one of the positive electrode and negative electrode is a common electrode on a top surface of the element layer, the common electrode lies over the partition wall, whereby having an upper surfaces along the partition walls, the upper surfaces including a first flat surface over the partition wall, a second surface being closer to the circuit board than the first surface, and an inclined surface between the first surface and the second surface, the sealing film contains an inorganic layer covering the element layer and contains an organic layer formed between a part of the common electrode and a part of the inorganic layer; the organic layer sits on a position between the second flat surface and the inclined surface and in contact with the common electrode, the upper surfaces of the common electrode have an inorganic contact area contacting the inorganic layer and have an organic contact area contacting the organic layer around the position between the second flat surface and the inclined surface; and the organic layer has an upper surface which is smaller than a lower surface thereof, the lower surface contacting the common electrode around the position between the second flat surface and the inclined surface.
