Patent ID: 7449829

Claim:
An organic electroluminescence display device comprising: a substrate; a first electrode formed on the substrate; a first organic electroluminescence layer provided on an upper layer of the first electrode; a second electrode provided on the first organic electroluminescence layer; a second organic electroluminescence layer provided on the second electrode; and a third electrode provided on the second electroluminescence layer, wherein at least one of the first and second electrodes is a transparent electrode for transmitting electroluminescence light emitted from the first or second electroluminescence layers, wherein a film is disposed between the first electrode which is a cathode and the first organic electroluminescence layer, or the film is disposed between the third electrode which is a cathode and the second organic electroluminescence layer, wherein said film is made of any one of: a) an alkaline metal; b) an alkaline earth metal; c) alkaline metal fluorides; d) alkaline earth metal fluorides; e) alkaline metal oxides; f) alkaline earth metal oxides; and g) an alloy or a compound of any one of a)-f) with another metal, and wherein a transparency of the transparent electrode can be maintained with suppressing a resistance value of the transparent electrode.
