Claim Text:
1. An organic electroluminescence display device comprising: a plurality of pixels formed in a display region, each of the plurality of pixels including an anode, an organic material on the anode, and a cathode on the organic material, each of the organic material and the cathode being shared by the plurality of pixels; a bank which is formed along a boundary of the pixel and covers a periphery of the anode; and a sealing layer which seals the plurality of pixels and includes a first inorganic insulation film, a resin on the first inorganic insulation film, and a second inorganic insulation film on the resin and the first inorganic insulation film; wherein the bank includes a first cliff-off portion, a second cliff-off portion and a forward taper slope portion, the first cliff-off portion is positioned above the anode and has a first side surface as a side surface of the bank, the first side surface being adjacent to an upper surface of the bank, the forward taper slope portion is positioned above the anode and has a second side surface as a side surface of the bank, the second side surface being adjacent to an upper surface of the bank, the second cliff-off portion is positioned below the first cliff-off portion and the forward taper slope portion and beside the anode, and has a third side surface as a side surface of the bank, the third side surface facing a side surface of the anode, each of an inclination angle of the first side surface and an inclination angle of the third side surface is larger than an inclination angle of the second side surface, the organic material and the cathode contact with the bank, the part of the anode contacts with the organic material, the organic material is connected to the cathode in a first region directly above the part of the anode, each of the organic material and the cathode is continuously formed from a second region directly above the second side surface of the forward taper slope portion to the first region directly above the part of the anode, and each of the organic material and the cathode is divided between a third region directly above the first side surface of the first cliff-off portion and the first region directly above the part of the anode.
