Method of fabricating an organic electroluminescent device

A method of assembling an electroluminescent device for displaying an image to a viewer in front of said electroluminescent device, comprising the steps of:

• depositing an anode layer onto a substrate;
• depositing an optical interference member onto said anode layer, said optical interference member reducing the reflectance of ambient light towards said viewer, said optical interference member having a wort function, said optical interference member comprising (i) a semi-absorbent layer comprising magnesium silver, and (ii) a transparent layer comprising indium tin oxide;
• depositing an organic electroluminescent layer onto said anode layer, said electroluminescent layer having an energy characteristics being the amount of energy required to extract an electron from said electroluminescent layer, said optical interference member having a thickness which causes destructive optical interference of ambient light, said energy characteristic being substantially equal to said work function such that the difference between the energy characteristic and the work function is from about 0.0 electron-volts to about 1.5 electron-volts;
• depositing a cathode layer onto said electroluminescent layer;
• and
• applying a sealing layer onto said cathode layer.

A method of fabricating electroluminescent device for displaying an image to a viewer when said viewer in front of said device after said device is fabricated, said method comprising the steps of:

• depositing an anode layer;
• depositing an organic electroluminescent layer above said anode layer, said electroluminescent layer having a highest occupied molecular orbital associated with an anode side, and a lowest unoccupied molecular orbital associated with a side opposite to said anode side;
• and
• depositing an optical interference member above said anode layer, said optical interference member reducing the reflectance of ambient light towards said viewer, said optical interference member having a thickness which causes destructive optical interference of ambient light, said optical interference member comprising (i) a semi-absorbent layer comprising magnesium silver, and (ii) a transparent layer comprising indium tin oxide, and wherein in the case that said optical interference member is disposed at said anode side, said optical interference member having a work function such that a first difference between said work function and a first energy level required to remove an electron from said highest occupied molecular is from about 0.0 electron-volts to about 1.5 electron-volts, and wherein in the case that said optical interference member is disposed at said side opposite to said anode side, said optical interference member having a work function such that a second difference between said work function and a second energy level required to remove an electron from said lowest unoccupied molecular orbital is from about 0.0 electron-volts to about 1.5 electron-volts;
• and
• depositing a cathode layer above said side of said organic electroluminescent layer that is opposite said anode side, at least one of said anode layer and said cathode layer being deposited above a substrate and at least one of said anode layer and said cathode layer being substantially transparent to electroluminescent light.
